Product description

The DT1310 … Intrinsically Safe Temperature / Resistance Transmitter provide signal transmission and conversion between Pt100 / Pt500 / Pt1000 sensor or resistance / potentiometer, – operate in potentially explosive area (zone 0, zone 1) – and the signal procession unit – operates in the safe area.
The transmitter feature complete 3-way isolation: the input to output and power supply circuits are isolated using state-of-the-art planar transformer design. The output signal may be 0-20 mA, 4-20 mA, 0-10 V, 2-10 V.
The Pt100 / Pt500 / Pt1000 / resistance / potentiometer can be connected to the input either with 2 / 3 or 4 wire.
The module features complete configuration of sensor input variables and process signal outputs.
Some of the configuration options are: sensor type, resistance range, signal output scaling, 2 / 3 or 4 wire measuring mode, signal filtering, calibrated sensor curve fitting, etc. The configuration software is capable of storing all the parameters for future reconfigurations. The configuration parameters are downloaded from the PC to the DT1310 … via wireless transmission.
Datcon provides a low cost USB-IR interface for this purpose, and a free of charge configuration software. Front panel LED indicators help the troubleshooting.
The overall full-scale accuracy of the module is < 0.1% and the temperature coefficient is < 50 ppm / °C.
The supply voltage range is 19-35 VDC, thus the transmitter is insensitive to the supply voltage change.
The transmitter’s ambient temperature range is -20°C to +50°C.
The module can be mounted on standard 35 mm DIN-rail and also features keyed plug-in terminals for easy and safe wiring.
