Drago DS7200 Series 3-Way Isolation Amplifier for Shunt Voltages

The 3-way isolation amplifier is used for electrical isolation and conversion of bipolar and unipolar shunt voltages. Input and output range can be set by using DIP switch. The zero/span adjustment on the front allows a fine-tuning of the measurement signal and the recalibration after a range selection. The 3-way isolation guarantees reliable decoupling of the sensor circuit from the processing circuit and prevents linked measurement circuits from influencing each other. The protective separation with high isolation level provides protection for personnel and downstream devices against impermissibly high voltage. The input signal is modulated and then electrically decoupled using a transformer. The isolated signal is then mAde available at the output, demodulated, filtered and amplified.
