Cabinet mounted dual loop PI-universal controller (X2 OS) low cost version

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.

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 and the EasySet program.
