RISHABH NA3 Digital Meter with BargraphUniversal input for the measurement of d.c. current,d.c. voltage and temperature, 3 or 7-colour bargraph. Programming of bargraph colour depending on the measured quantity value. Signalling of set alarm value overflow. Storage of measured signal in programmed time segments (750 samples). Current or voltage analog output. Communication in SCADA systems (RS485/Modbus interface RTU and ASCII).Galvanic isolation on with resolution on 0.025% of range; current programmable 0/4...20 mA, load resistance = 500 ( or voltage programmable 0...10 V, load resistance = 500 (, output response % m e: 100 ms.
