TCX2-23343 Dual loop controller (X2 OS) ideal for VAV zone control

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.

The TCX2 communication MODBUS controllers are designed as universal controls equipment suitable for a large number of applications. They may be used in zoning applications which are monitored by a MODBUS RS485 network.

The controllers communicates on a BACnet MS/TP network over RS485 is suitable for a large variety of applications such as zoning applications residential and commercial, air handling units, economizers, etc.

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.
