The nVent RAYCHEM remote monitoring module (RMM2) provides temperature monitoring capability for the NGC-30, NGC-40 and ACCS-30 heat tracing control and monitoring systems. The RMM2 accepts up to eight RTDs that measure pipe, vessel, or ambient temperatures in a heat tracing system. The RMM2 modules are used to aggregate RTD sensors in one remote location and send the information back to the advanced control system through a single twisted pair cable. This helps reduce installation costs since only one conduit run returns to the controller, rather than eight. Multiple RMM2s communicate with a single NGC-30, NGC-40 or ACCS-30 to provide centralized monitoring of temperatures. A single, twisted pair RS-485 cable connects up to 16 RMM2s for a total monitoring capacity of 128 temperatures.
