TCM2
Features
- Dual-circuit system
- Control & monitoring
- Up to 2 circuits
Application
The Thermon TraceNet TCM2 is a microprocessor based temperature control and monitoring module developed specifically for heat tracing applications. The unit provides control and monitoring capabilities via digital information display for one or two heat tracing circuits with input from up to two RTDs per circuit.
Up to 247 TraceNet TCM2 modules can be interconnected in a RS485 communication network, for a total cumulative distance of up to 1220 meters. For additional communication distances, a repeater option is available.
Features
A TCM2 control and monitoring unit offers the following features:
- Reduces Man-hours:
With the simplified, 4-button user interface, operators can quickly program the TCM2. The new TCM2 wiring harness allows maintenance personnel to swiftly install, remove, and conduct troubleshooting of the system. - Improved Control Methods:
The TCM2 utilizes multiple control methods, similar to the Thermon TCM18 (On/Off, Soft-Start, Proportional) and features the upgraded Ambient Proportional Control (APC and APCM) that employs the energy saving method of Ambient Proportional Control with the higher current capacity of the mechanical relay. - Upgraded Communications:
The TCM2 can network with any Thermon Controller to the Genesis Network or any plant DCS system via RS-485 in either MODBUS ASCII or RTU. In the panel, the TCM2 can employ a converter to offer MODBUS TCP/IP Ethernet.
