GMA 44B One to Four Channel Controller

GfG Instrumentation, 2044001, GMA 44B One to Four Channel Controller without Output SignalIncludes:Digital LED displayExternal reset connectionFeatures:Single channel controller or one to fourchannel controllerIntuitive push-button operationEasy installation on standard DIN rail4 - 20 mA input standard(factory configured to 0.2 - 1 mA)3 user-adjustable alarm pointsUser-adjustable alarm hysteresis4 relays (3 alarm and 1 fault)Din rail power supplies availableFactory configured alarm functions(Latching/non-latching, Resettable/non-resettable, Time delay, Rapid rise alarm for combustiblesetups)The GMA 44 4-channel controller is an integral part of safe and reliable gas warning systems. Every alarm in the GMA can be individually adjusted. False alarms are eliminated with the adjustable alarm delay. The point values can be freely adjusted within the detection range. They can also be adjusted later with the control keys to adapt to changing requirements. Every point value can be selected to be latching / nonlatching or resettable / non-resettable.Every controller provides four voltage-free relays for the three alarms and the fault warning. The relays may be used to control external alarm devices like lights or horns. They can even introduce specific counter measures to prevent or limit dangers from gases or vaporsThe GMA (variant B) offers an integrated BUS-system. The BUS-system supplies power from one source to all connected GMAs. The BUS-system also connects individual controller alarms together so that, with the use of the keyoperated switch, all connected monitors have one collective alarm. Several GMAs can be connected easily without additional wiring.
