TraceNet™ ECM Thermon

TraceNet™ ECM Thermon (LECTRONIC CONTROL MODULE)

APPLICATION
The TraceNet ECM is an electronic control module specifically
designed for controlling electric heat trace circuits used in freeze
protection and temperature maintenance applications. The ECM
serves both the temperature control as well as the sensor and
power connection for a heat trace circuit.
The ECM is housed in a glass reinforced nonmetallic enclosure
with an environmental protection rating of IP66. Depending
on options selected, the ECM may be used as a combination
temperature control and limiter, a temperature controller
with either low or high temperature alarm, or a temperature
limiter. Rotary switches are provided for adjusting temperature
control and limiter set points. The standard version of the ECM
communicates on a physical network of RS485 by using a Modbus
RTU communication protocol.
The ECM is approved for use in both ordinary (non-classified)
and hazardous (classified) areas.
The ECM-OS is available in a stainless steel junction box for use
in offshore applications. (Refer to Form TEP0138)
