Intrinsically safe electrical safety barrier DAT4235-IS-A

for sensors

The DAT 4235 IS device is a galvanic isolated Intrinsically Safety Barrier, defined as “Associated Apparatus” The input measures mV, V, mA or resistance signals, and can be directly connected to Thermocouple, RTD or potentiometer sensors. The input signal is filtered, linearised, amplified and transferred to the output circuit, that converts it in a 0-10V range or 0-20mA range signal. Auxiliary power supply allows to supply the output current loop. DAT 4235 IS has a 3 way isolation: input (connected to hazardous area devices) is 2000 Vac isolated from power supply and output (connected to safe area); power supply and output are 1500 Vac isolated between them. The configuration is made by means of personal computer through the PRODAT-IS interface. Protection mode: II (1) G [ Ex ia Ga ] IIC II (1) D [ Ex ia Da ] IIIC according to the Directive ATEX 2014/34/EU
