Dual loop controller ideal for zoning and general applications. 230VAC and 24V versions available

The TCX2 is a programmable electronic universal controller with communication capabilities. Each control loop may use 2 PI sequences and 6 binary stages. The TCX2 comes with a built in RS485 communication interface that allows peer to peer communication with an operation terminal.

Communication plug-ins allow for integration of the controller into a network (BACnet and MODBUS).

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-PM1 or exchanged with a PC using an RS485-USB converter and the EasySet program.
