D1500 Strain Gauge Input Modules


The D1500 strain gauge input and load cell measurement modules contain an isolated 15-bit analog to digital converter to measure strain gauges, load cells and sensors with a resistive bridge output. Each strain gauge module includes an isolated excitation voltage source to excite the strain gauge, eliminating the need for an additional voltage supply. The onboard excitation allows the module to compensate for changes in ambient temperature during the measurement process. Measurement ranges include +/-30mV, +/-100mV, and 1-6Vdc. Available excitation voltages include 5V, 8V and 10Vdc, 60mA max current output.

The D1500 strain gauge and load cell measurement modules perform all signal conditioning, analog to digital conversion, and linearizes the digital data into scaled engineering units. The load cell and strain gauge data values are transmitted to a host computer via an RS-232 or RS-485 serial port.

The D1500 load cell input and strain gauge input modules contain one discrete open-collector digital output that can be used to control solid-state relays, annunciators, or perform an On/Off LO alarm function based on the scaled data values. The output can be pulled up to +30Vdc and sink up to 30mA without damage.
