PolyGard®2 Multi Gas Controller MGC2-X-XX3X2300 GasAlarm

Description

PolyGard®2 Multi Gas Controller MGC2-X-XX3X2300 GasAlarm

Gas measuring, monitoring and warning controller based on state-of-the-art micro-technology for continuous monitoring of the ambient air to detect toxic and combustible gases, refrigerants or oxygen.

The Multi-Gas-Controller is designed for the connection of maximum analog three sensors with 4-20 mA signal, e.g. of the MC2 series. The controller monitors the measured values and activates the alarm relays if the set alarm thresholds for pre-alarm and main alert are exceeeded. In addition, the values are provided for direct connection to a superior BMS via an RS-485 interface and also as 4-20 mA output.

The SIL 2 compliant self-monitoring function in the MGC2 activates the fault message in case of an internal error as well as in case of a fault at the 4-20 mA input / output current signals.

Other options such as three-color status LED, warning buzzer, digital input for acknowledgment or test function, various communication protocols ensure proper adaptation to the wide range of applications in gas detection technology.

 

APPLICATION

The MGC2 is designed for detection and warning of gases in many commercial and industrial applications. Consisting of 3 analog sensor cartridges (MC2).
