Datexel Temperature Transmitter and Signal Converter - DAT4235 IS/A

Current and Voltage Input, Thermocouple Input, Current and voltage Output

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. Moreover, the device is able to control two trip alarm relay outputs.

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 “ DAT 4235 IS /A ” model converts the input signal in analogue output, the “ DAT 4235 IS /B ” model controls two output trip alarms. The “ DAT 4235 IS /C
model is able both to converts the input signal in analogue output and to control two output trip alarms.

Configuration and configuration is made by means of personal computer through the PRODAT-IS interface.

The device must be powered with a voltage between 20 and 30 Vdc; the “PWR” green led turned on indicate the correct power supply; the "THR1" and "THR2"
red led indicates the trip alarm status.

The device is housed in a rough self-extinguish plastic enclosure of 22.5 mm thickness suitable for DIN rail mounting.

DAT4235IS/A from Datexel comes with the following features:

  • Protection mode: II (1) G [ Ex ia Ga ] IIC -- II (1) D [ Ex ia Da ] IIIC -- according to the Directive ATEX 2014/34/EU
