Product description
A Compact 7-Inch Controller with Defined I/O Capacity
The LINO Touch SE+ is built around a defined 7-inch control platform rather than a large expandable controller architecture. It combines 15 relay outputs, four variable-speed control channels, environmental sensor inputs and three RS485 interfaces in one unit.
SE+ is suited to poultry-house projects whose equipment list can be organized within a fixed relay budget. Buyers can compare the required fan groups, air inlets, auxiliary functions and communication interfaces with the published capacity before selecting the controller.

How the 15 Relay Outputs Are Allocated
The controller provides 15 relay outputs for project-specific equipment control. These outputs may be assigned to fixed-speed fan groups, air-inlet actuators, heating, a cooling pump, fogging equipment, a timer and alarm functions according to the approved control plan.
Because the outputs are shared across these functions, the final relay schedule should be confirmed before production. A clear allocation table helps prevent over-assignment and supports commissioning, operator training and later maintenance.
Four Variable-Speed Channels and 24 Ventilation Stages
LINO Touch SE+ supports up to four variable-speed fan control channels and up to 24 ventilation stages. The variable-speed channels can be used as part of a proportional ventilation sequence, while the relay outputs can stage fixed-speed fan groups as demand increases.
The 24 stages describe the available ventilation sequence, not 24 independent controllers or guaranteed energy-saving modes. The final sequence must be programmed around the actual fan groups, motor-control hardware and house ventilation design.
Fixed-Speed Fan Groups: Up to Ten Groups
The current SE+ configuration supports up to ten fixed-speed fan groups. A fan group may contain one or more fans assigned to the same control stage, so the capacity is described as fan groups rather than ten individual fans.
Before ordering, list each fixed-speed fan group, its motor-control method and its intended ventilation stage. This allows the ten-group capacity to be checked against the poultry-house ventilation plan.
Four Air-Inlet Groups with Negative-Pressure Input
The controller supports up to four air-inlet or curtain groups and one negative-pressure input. This allows the control strategy to coordinate inlet opening with the selected fan stages when the actuator and electrical design support the required sequence.
Projects that require inlet-position feedback, proportional 0-10V control or a specific actuator interface should confirm those functions separately before ordering, because they are not included in the published SE+ specification.
Environmental Inputs for Temperature, Humidity and Air Quality
LINO Touch SE+ supports up to seven temperature sensors together with one humidity input, one CO2 input, one NH3 input and one negative-pressure input. These signals provide the controller with the environmental information needed for the selected ventilation and alarm logic.
Supported input capacity does not mean that every sensor is supplied as standard. Sensor type, measurement range, calibration method and installation position should be confirmed for the project.
Heating, Cooling Pump, Fogging and Timer Functions
The published SE+ configuration includes one heating group, one cooling-pump group, one fogging system and one timer function. These outputs allow selected auxiliary equipment to be included in the controller sequence within the available relay budget.
High-power equipment may require external contactors, motor protection or a separate electrical cabinet. Cooling equipment should be specified separately according to the project design.
Three RS485 Interfaces for Project-Specific Integration
The controller specification lists three RS485 interfaces. Their value is the availability of separate communication channels for project-specific integration, subject to confirmation of the protocol, wiring, register map and connected equipment.
The protocol, wiring method, register map and connected devices should be confirmed before configuration. Buyers should provide the communication documentation for any third-party equipment that must exchange data with the controller.
Touchscreen Operation, Alarm Review and USB Updates
The 7-inch touchscreen provides access to environmental values, equipment status and alarm information. Operators can review current conditions and approved control settings from one local interface.
Alarm records and USB-based system updates are available according to the selected configuration. Record capacity, user permissions, interface language and update procedure should be confirmed before ordering.
PC and Smartphone Communication: Define the Required Configuration
The product supports PC and smartphone communication according to configuration. The required network hardware, software platform and available remote functions depend on the selected project arrangement.
Before ordering, specify whether the project requires local PC viewing, remote monitoring, alarm access or another communication method so that the required components can be confirmed.

Where SE+ Fits Within the Controller Range
SE+ is the fixed-capacity 7-inch option in the Illinois environmental-controller range. The basic SE, 10-inch MAX, relay-expandable Pro+ and higher-capacity LN-9900 use different I/O and expansion structures.
Selection should be based on the equipment list, relay allocation, variable-speed channels, ventilation stages, sensor inputs and communication requirements rather than on model size alone.
Project Information Needed Before Relay Assignment
Before the 15 relay outputs can be assigned, the buyer should provide the fixed-speed fan groups, variable-speed control requirements, four air-inlet or curtain groups, heating, cooling pump, fogging, timer and alarm priorities.
The electrical drawing must also identify the local voltage, external contactors, motor protection and any existing control cabinet. This information determines whether the fixed relay architecture can support the required operating sequence.

When LINO Touch SE+ Is the Right Fit
LINO Touch SE+ is a practical choice when the project requires a 7-inch local interface, a fixed 15-relay budget, four variable-speed channels, up to ten fixed-speed fan groups, four air-inlet groups, up to 24 ventilation stages and three RS485 interfaces.
Projects that exceed this relay or equipment scope should be reviewed against MAX, Pro+ or LN-9900 before the control plan is finalized. Model selection should be based on the approved equipment list rather than on screen size alone.
Information Required for an SE+ Configuration
Before preparing a LINO Touch SE+ configuration, the buyer should provide:
- poultry-house layout and equipment locations;
- fixed-speed fan groups and variable-speed control requirements;
- required ventilation stages;
- air-inlet or curtain quantities and actuator type;
- temperature, humidity, CO2, NH3 and negative-pressure monitoring requirements;
- heating, cooling-pump, fogging, timer and alarm requirements;
- local voltage, electrical drawings and protection devices;
- RS485 and PC or smartphone communication requirements;
- required interface language and OEM scope, when applicable.
This information is used to confirm relay allocation, communication requirements and the final controller configuration.
Frequently Asked Questions
What makes LINO Touch SE+ different from the larger 10-inch controllers?
LINO Touch SE+ uses a 7-inch fixed-capacity architecture with 15 relay outputs, four variable-speed control channels, up to 24 ventilation stages, four air-inlet groups and three RS485 interfaces. It is suited to projects whose equipment list and control sequence fit this defined capacity.
How should the 15 relay outputs be allocated?
The relay outputs should be assigned according to the required fixed-speed fan groups, air inlets, heating, cooling pump, fogging, timer and alarm priorities. The final allocation must be confirmed before production because not every listed function can be assumed to operate at maximum quantity at the same time.
Can SE+ combine variable-speed and fixed-speed ventilation?
Yes. The controller supports up to four variable-speed control channels and staged operation of up to 10 fixed-speed fan groups through up to 24 ventilation stages. The final sequence must match the installed fans, motor-control hardware and poultry-house ventilation plan.
What do the 24 ventilation stages represent?
They represent the available sequence for changing ventilation output as control demand changes. They do not mean 24 independent controllers or guarantee a specific energy-saving result. The stage sequence must be programmed around the installed fans and air inlets.
Which environmental inputs are listed for SE+?
The current product information lists up to seven temperature sensors, one humidity input, one CO2 input, one NH3 input and one negative-pressure input. Supported inputs do not automatically mean that every sensor is included as standard.
Can the controller coordinate four air-inlet groups with negative pressure?
The controller supports up to four air-inlet or curtain groups and one negative-pressure input. The opening sequence, actuator type and electrical interface must be defined in the project design. Projects requiring inlet-position feedback or proportional control should confirm those functions separately before ordering.
Which auxiliary functions can use the relay outputs?
The published configuration includes one heating group, one cooling-pump group, one fogging system and one timer function. Their use depends on the final relay allocation and external electrical components.
What are the three RS485 interfaces used for?
The three RS485 interfaces provide communication channels for project-specific integration. The protocol, wiring method, register map and compatible devices should be confirmed before configuration.
Can SE+ directly power large fans, heaters or pumps?
SE+ provides control outputs for connected equipment, but high-load fans, heaters and pumps may require external contactors, motor protection or a separate electrical cabinet. The final power circuit should follow the equipment rating and project electrical design.
What information is required before ordering an SE+ controller?
The buyer should provide the house layout, fixed-speed and variable-speed fan requirements, ventilation stages, four air-inlet groups, sensor requirements, auxiliary equipment, local voltage, electrical drawings, RS485 needs and PC or smartphone communication requirements.
