GasGard XL

The GasGard XL Controller from MSA is a versatile and easy to use multi-channel, wall-mounted controller for monitoring toxic and combustible gases, and oxygen deficiency. This controller provides protection from potentially hazardous conditions in a variety of industrial, chemical, municipal, and waste water applications. The GasGard XL Controller offers reliability in a compact, durable, wall-mounted housing constructed of fire-retardant ABS plastic. The large and clear multi-language LCD display provides real-time target gas readings and events, offers full system diagnosis, and is supported by individual LEDs per channel with common relays and internal buzzer.

The GasGard XL Controller can be easily configured to accept up to eight remote gas sensors, depending upon the number of individual plug-in input cards installed. With two alarm levels per channel, the GasGard XL Controller operates in conjunction with MSA’s remote gas sensors (combustible, toxic, or oxygen 4 –20 mA). Ideal for use with MSA Ultima® X Series Gas Monitors, FlameGard® Flame Detectors, and SafEye™ Open Path Gas Detection Systems, this controller’s ergonomic design allows for efficient wiring and installation.
