TCI2-204.202UC Cabinet mounted dual loop communicating PI-universal controller (X2 OS)

The TCI2 is a programmable universal controller with communication capabilities. Each control loop may use 2 PI sequences and 2 binary stages. The TCI2 comes with a built in RS485 communication interface that allows peer to peer communication with an operation terminal such as OPA2-(2TH)-VC.

Communication plug-in allow for integration of the controller into a network. These modules are described in their own manual. Currently available are plug-ins for BACnet and MODBUS. There is also a Wi-Fi and Ethernet 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.

Flexible application configuration is made with a parameter-setting routine using the standard operation terminal.

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