DIN-150 Modbus Strain Gauge Input Modules


The DIN-150 strain gauge input modules contain an isolated 15-bit analog to digital converter and measures resistive strain gauge or load cell sensors.  Each module is hardware optimized to measure either 3mV/V or 10mV/V sensors and includes a DC excitation output voltage source of either +5V or +10Vdc.  The excitation voltage output can source up to 50mA to the sensor.

The DIN-150 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 input range. The data values are transmitted to a host computer using the Modbus RTU serial protocol via an RS-485 serial port.
