Allen Bradley Signal Conditioners

Allen Bradley signal conditioners are electronic devices that improve signal quality by transmitting process measurements from field equipment to the control system accurately. These signal conditioners employ transformer-coupling technology to isolate signals galvanically and reproduce those signals as accurately as possible. Signal conditioners can protect important signals from noise, ground loops, and harsh operating conditions. Signal conditioners can be used to improve the quality and accuracy of flow, pressure, temperature, speed, weight, frequency, current, and voltage signals.
