PolyGard 2-channel Gas Controller MGC-03 DESCRIPTION Gas measuring and monitoring controller based on state-ofthe-art micro-technology with integrated buzzer for continuous monitoring of the ambient air and detecting toxic and combustible gases and vapours as well as oxygen and Freon refrigerants. Other physical values with analog output signal can be connected as well. The MGC-03 is equipped with two analog inputs for the connection of external transmitters including detection of wire break and short-circuits. Up to four alarm thresholds are free programmable per input. Two alarm relays and one open collector output are available for the alarm messages. Configuration and operation are possible via the logical, simple system menu structure without specific programming knowledge. APPLICATION The MGC-03 is suitable for a wide range of commercial and industrial applications. Free programmable parameters and set-points enable the individual adaptation to a variety of possible applications in the field of gas measuring and monitoring. Standard enclosure FEATURES Suitable for toxic and combustible gases and vapours, oxygen, refrigerants, temperature, pressure, humidity etc. Logical menu structure in different languages Simple, fast commissioning due to pre-configuration with standard parameters and set-points Comfortable calibration and maintenance Four free programmable alarm thresholds per channel Modular design (plug-in technology) Two analog inputs for transmitters with standard current/ voltage signals Two alarm relays, potential-free, max. 3AC/DC, 0,5 A One open collector output, max. 3DC, 50 ma (0) 4 20 ma / (0) 2 10V analog signal output, freely configurable IP 65 version Enclosure fire-resistant according to UL 94V2 Integrated warning buzzer with reset function Approved according to EN 61010-1; ANSI/UL 61010-1; CAN/CSA-C22.2 No. 61010-1 23AC operating voltage (option) Up to three power relays (potential-free, max. 25AC, 5 A) (option) Uninterruptible emergency power supply (option) LED flash light red (option) 3 x warning lights, colours green red orange selectable (option) External warning horn (87 db) mounted on the housing (option) External multi-sound horn mounted on the housing (option) Heating (option) MSR Electronic GmbH Würdingerstr. 27a 94060 Pocking GERMANY 1 Mar 13
