E-700 SERIES SIGNAL CONVERTERS ■ DESCRIPTION E-700 Series signal converters are new generation microcontroller based industrial instruments in a plastic case. E-700 Series are general purpose converters which can be used to convert thermocouples, resistance thermometers and other sensor voltages, currents or pulses to standard currents. The E-700 Series have a wide-range of applications, especially for integration of SCADA, DCS, PLC systems through RS485 interface unit. Filtering features avoid the effect of electrical noise activity in industrial areas. The configuration of the converter is performed by PC using a software program supplied by Elimko. The RS232 connection hardware is also available from Elimko. ■ TECHNICAL SPECIFICATIONS Accuracy Class 0.5 (0.2 for linear outputs) Noise Suppression 120 dB at 50 Hz Operating Temperature -10÷50°C Operating Voltage 85–265 V AC 85–375 V DC 20–60 V AC 20–85 V DC Min.
