The CIC-SG71 and the new SG78 are DIN Rail Mountable Strain Gauge Signal Conditioners. The CIC-SG71 can be used to condition the signal from any transducer with an output of 0.2 mV/V up to 15.0 mV/V.
The CIC-SG71 can be powered from any 18 to 36 VDC source and requires less than 200 mA to operate. The power supply inputs are internally isolated to eliminate any grounding or common problems thus eliminating the need to have a separate power supply for your signal conditioning.
The CIC-SG71 provided a very precise excitation voltage to the transducer at 2.5, 5.0 or 10.0 VDC up to 100 mA. Outputs from the CIC-SG71 are selectable at 0 to 10, +/- 5, +/- 10, or 4-20 mA and are filtered at 1 kHz. High frequency response is optional up to 10 kHz. The CIC-SG71 also has an externally activated shunt calibration circuit as well as provisions for bridge completion resistors.
The SG78 Carrier Based Signal Conditioner has the same superb signal processing capabilities as the SG71 and is designed to work either a Transformer Based Torque Sensor or a Direct Wired Strain Gauge installed in a harsh industrial environment.
