SRD2-212.002U

Image description

Wall-mounted programmable controller and transmitter (X2 OS) with internal temperature and humidity sensor and optional CO2-sensor, color display, PIR sensor. 2 control loops, 2 universal analog inputs (RT/DI/VDC/mA) and 2 universal outputs (VDC/mA)

The SRD2 is a programmable controller and transmitter with communication capabilities. Each control loop may use 2 PI sequences and 2 binary stages. The SRD2 comes with a built-in isolated RS485 communication interface that allows peer-to-peer communication with an operation terminal such as OPT1-(2TH)-VC. An optional built-in color display and touch buttons provides a perfect and flexible way to interact with the user.

Communication supports Modbus.

Complete parameter sets may be copied by use of an accessory called AEC-PM2 or exchanged with a PC and the EasySet program using an RS485-USB converter or via Wi-Fi.

The SRD2 uses the Vector Controls universal and flexible X2 operating system and is preconfigured as described in the manual.

Applications

  • Ventilation control 
  • Temperature control 
  • Air humidifier and dehumidifier
  • CO2 air quality control 
  • Motion detection action
