The SRD2 is a programmable controller and transmitter with communication capabilities. Each control loop may use 2 PI sequences and multiple 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 OPD2-TH-VC-TOPIR. An optional built-in 3.5 in touch screen or a color display with touch buttons provides a perfect and flexible way to interact with the user.
Communication supports BACnet or Modbus. There is also a Wi-Fi communication option available which supports Modbus TCP and BACnet/IP. An embedded webserver provides a web interface to access the controller in order to change the connection settings and to operate the controller.
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
