The MAQ20-BRDG1 strain gage module offers four input channels and can interface to full-, half- and quarter-bridge sensors using four- or six-wire connections. All channels are configurable individually for range, alarm limits and averaging; in addition, sampling rate, resolution, bandwidth, excitation voltage and choice of shunt calibration resistors are user-settable parameters. The MAQ20 frequency input module accepts zero-crossing and TTL signals with frequencies from 1 Hz to 1 MHz plus state change and provides a dc stimulus for contact sensors. The module has a -40 to 85 °C industrial operating temperature.
