Model GM-A Digital Display/Signal Conditioner DESCRIPTION The GM-A is a cost-efficient digital readout that works with amplified (0 V to 5 V or 4 mA to 20 mA) transducers or transmitters. This unit supplies power to the sensors. Two-wire current is user jumper selectable for use with two-wire current transducers. Separate power supply required for three-wire current use. Not for use with intrinsically safe applications utilizing a barrier. FEATURES • High level (amplified) transducer input • 4 1/2 digit LED display • Large 14,2 mm [0.56 in] readout • High speed analog output • Transducer current drive 30 mA (max.)
