Fema Electronica EZ4-ZR3 is a multisignal digital panel meter with 4 relays and analog output. Configurable to read AC and DC voltages (up to 600 V), AC and DC amperes (up to 5 A), process signals (mA and Vdc) with and without excitation voltage, thermocouples K, J, E, N, L, R, S, B, T and C, temperature probes Pt100 with 2 and 3 wires, Pt500, Pt1000, Ni100, Ni200, Ni1000, PTC and NTC, resistances, potentiometers and frequency. AC measures in True RMS. 

Standard 96 x 48 mm (1/8 DIN) size. Scalable reading with 4 digits (9999 to -1999) and configurable decimal point. ‘Fast access’ function to alarm setpoints, external contact for special functions, ‘Eco’ mode for reduced consumption, 5 brightness levels. Single universal power supply 18 to 265 Vac/dc. Includes 4 relays SPST and 1 analog output 4/20 mA isolated .
