Control and Monitoring Systems

The Raychem ACS-30 system provides electronic control and monitoring for multi-circuit heat tracing applications, including pipe frost protection, surface snow melting, hot water temperature maintenance, gutter and roof de-icing, temperature flow maintenance, and electrical underfloor heating. The Raychem ACS-30 can control up to 260 heat tracing circuits of any application, from a single user interface, allowing building owners and facilities managers to monitor and manage their Building's heat tracing systems from a single point.

Power and control modules (PCMs) can be positioned throughout the building in accordance with the building system requirements. Multiple PCMs can be connected together providing a complete view of the buildings heat tracing systems.

The PCM module also provides:

• Ground fault monitoring.
• Line current monitoring.
• Alarm capability.
• RTD (Resistance Temperature Detector) input capability for each individual heating circuit.

ACS-30-EU-MONI-RMM2-E:

Remote monitoring module (RMM) for the ACS-30 control and monitoring system, to measure additional temperatures for control and monitoring of heating cable circuits. Up to 16 RMMs may be controlled by a single UIT, with up to 8 RTDs per RMM.

• One RMM provides up to eight sensor inputs per module with feedback to the ACS-30-EU-UIT2.
• Maximum 16 RMM devices per User interface terminal (UIT).
• Twisted pair RS-485 cable connects up to 16 RMM units providing 128 additional temperature monitoring sensor inputs.
• Remotely located adjacent to the desired measurement locations.
• ACS-30-EU-MONI-RMM2-E module comes pre-installed inside a compact enclosure.

ACS-30-EU-EMDR-10-MOD:

• Provides smart sensor input for roof and gutter de-icing applications.
