Gas Detection Controllers

Dedicated units that monitor one gas detector and provide local alarm and relay outputs. Used for point protection of a single hazard location such as a specific compressor or storage area.

Controllers that accept inputs from several detectors on independent channels, each with its own setpoints and alarm relays. Suited to monitoring multiple zones from a single panel.

Controllers with a graphical touchscreen interface for live readings, trending, setpoint configuration, and event logging. Simplify configuration and operator visibility versus pushbutton-and-LED panels.

Compact modular controllers that mount on standard 35 mm DIN rail inside an enclosure or cabinet. Used where panel space is limited or detection logic is integrated into an existing control cabinet.

Controllers certified to a Safety Integrity Level (typically SIL 1-2) under IEC 61508/61511 for use in safety instrumented functions. Selected when gas detection drives executive shutdown actions requiring a quantified failure probability.

Controllers with digital communication ports (commonly Modbus RTU/TCP) that report channel status and alarms to a PLC, DCS, or SCADA host. Enable centralized monitoring and integration with plant control systems.

Card-based systems housed in a 19-inch rack where each detector channel is a plug-in module sharing a common power supply and relay frame. Used in large fixed installations with high channel counts.

Controllers that poll many addressable detectors over a shared field bus loop rather than individual home-run wiring. Reduce cabling on large or distributed sites while retaining per-detector identification.
