Multi-Gas Controller MGC2

Description: The Multi-Gas Controller MGC2 facilitates the connection of up to three analog sensors with 4–20 mA signals, such as those from the MC2 series. This controller actively monitors the measured values and triggers alarm relays upon exceeding predefined thresholds for pre-alarm and main alert levels. Additionally, it provides values for direct integration with a superior Building Management System (BMS) via an RS-485 interface and as 4–20 mA output.

Application: The PolyGard®2 Multi-Gas Controller MGC2 is tailored for detecting and alerting against gas presence in various commercial and industrial settings.
