DIN-145 Modbus Thermistor Input Module

$220.00

The DIN-145 Thermistor input modules contain an isolated 15-bit analog to digital converter and measure Thermistor temperature sensors. Each module is hardware optimized for the best measurement performance over the sensor input range. Two different thermistor input modules are available, 2252 Ohms and the Honeywell TD series.

The DIN-145 performs all signal conditioning, the analog to digital conversion and produces a linearized temperature output. The values are scaled in 16-bit unsigned integer format that represents a percentage of the full scale temperature range. The data values are transmitted to a host computer using the Modbus RTU serial protocol via an RS-485 serial port.

The DIN-145 module easily mounts on industry standard 35mm DIN-rail.

Ranges:
2252: -0 to +100 C
TD: -40 to 150 C

Accuracy:
2252: +/-0.1 C
TD: +/-0.2 C
