Sensor and Control Module

Distributed on/off, multi-speed and variable speed control module with optional sensor inputs for use with DGC6-series digital gas controllers.

Conformed to Safety Integrity Level 2 (SIL 2) and rigorous international standard EN 50545-1 for parking garages and tunnels, PolyGard®2 monitoring and control systems utilize advanced self-diagnostics and flexible ventilation control functions to ensure maximum human safety without compromising energy efficiency.

Each SCM6 includes two relays and one analog output and may be configured with one or two integrated SC2 sensor modules with X-Change sensor technology.

Advanced, microprocessor-based X-Change sensor modules meet or exceed the EN 50545-1 self-diagnostic standards including notifying the controller when calibration is due. Although field calibration is possible, X-Change technology allows fast and cost-effective sensor module swaps minimizing field service time, eliminating system downtime and ensuring peak system performance for many years.
