The DSCA36 isolation amplifier provides a galvanically isolated input channel for the connection of potentiometric encoders. The input signal is filtered, isolated and converted into a process output Signal. The input signal is converted into a DC voltage signal by an AC-coupled input amplifier and an RMS converter. After field-side filtering, the signal is converted by a proprietary chopper circuit. Isolation is provided by transformer coupling, again using a proprietary technique to suppress transmission of common mode spikes or surges. The line compensation is realized by 3-wire circuit. The excitation current is small (approx. 0.25mA) which minimizes self-heating of the sensor.

The module output is either voltage or current. For current output models a dedicated loop supply is provided at terminal 3 (+OUT) with loop return located at terminal 4 (-OUT). The system-side load may be either floating or grounded.

Special input circuits provide protection against accidental connection of powerline voltages up to 240VAC and against transient events as defined by ANSI/ IEEE C37.90.1. Protection circuits are also present on the signal output and power input terminals to guard against transient events and power reversal. Signal and power lines are secured to the module using screw terminals which are in pluggable terminal blocks for ease of system assembly and reconfiguration.

The modules have excellent long-term stability and do not require recalibration, but zero and gain are adjustable (±5%) to allow fine tuning if desired. Adjustments are made using potentiometers located under the front panel label.
