Tracenet ECM-C-12
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.
PRODUCT SPECIFICATIONS TraceNet™ ECM™ ELECTRONIC 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)
