Modulating Modbus Room and FCU Controllers | SRC-110-MOD Modbus Heating and Cooling Room Controller, DIN-Rail

Modbus Heating and Cooling Room Controller, DIN-Rail

DOCUMENTATION
Datasheet (603kB)

The SRC-110-MOD Modbus series controllers have been designed for zone heating and cooling control and DIN-rail mounting. The controllers have 3 analogue 0..10Vdc outputs and two digital outputs that can be configured for heating and cooling control. The controllers can operate as Proportional Only or as Proportional + Integral Controllers. The controllers have built-in Modbus RTU RS485 communication for connection to BMS systems.

The controller can have up to 2 heating and cooling stages. The analogue outputs can be individually configured for any of the heating/cooling stages and digital outputs can be configured as 3-point, PWM (thermic) or On/Off control.

The controllers are connected to either TER-NTC10 room temperature sensor or TEKY-NTC10 flying lead sensor for temperature measurement. If room setpoint is required then TER-NTC10-SPR sensor can be used together with the SRC-110-MOD DIN-rail mounted Modbus room controllers.

The controller configuration parameters are adjusted thrrough the SW-DCT-USB tool. Red and blue LEDs under the cover indicate the controller operation in heating or cooling mode and can be used for servicing the controllers.

The controllers have built-in Modbus RS-485 communication for connection to BMS systems.
