Remote Modules for Control (RMC)

The DigiTrace NGC-30 system also includes integrated control functionality. Multiple relay outputs to operate contactors of each heat-tracing circuit will be provided by Remote Modules for Control (RMC). Temperature inputs will be provided by Remote Monitoring Modules (RMM) while the control is executed by the UIT. DigiTrace RMC units are modular and may be configured with 2 to 40 relay outputs.

Each RMC unit also includes two digital inputs (DI) to monitor the status of circuit breakers or power contactors. A single UIT control unit can communicate with up to 10 RMC modules via a single, twisted pair RS-485 cable to provide distributed control of up to 250 heating cable circuits with a maximum of 128 temperature inputs (see DigiTrace RMM below). For more information refer to the datasheet of DigiTrace MONI-RMC. Circuits controlled via RMCs, can’t be combined with the current transformers (CTM).
