The CGC6 Compact Gas Controller provides human interface and ventilation control functions for gas monitoring systems with up to 10 self-addressing sensors on a 4-wire, RS-485 serial communication bus. Each DT6A field device monitors one toxic or combustible target gas. Gas types may be mixed on one CG6 Controller. DT6A-series sensors are uniquely designed for field addressing via on-board push-button.

This easy to commission system provides SIL 2 compliant reliability through continuous self-diagnostics of hardware, software, and communications.

CGC6 is a low-cost solution for monitoring up to ten toxic and/or combustible gas sensors of the same or mixed gas types in a single ventilation zone.
