DIN-130 Modbus Thermocouple Input Modules


The DIN-130 thermocouple input modules contain an isolated 15-bit analog to digital converter and measure thermocouple temperature sensors. Each module is hardware optimized for the best measurement performance over a thermocouple input range. Eight different thermocouple input ranges are available.

The DIN-130 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.
