Transmitter Power Supply

This signal conditioner provides galvanic isolation for non-intrinsically safe applications. The device supplies 2-wire and 3-wire transmitters, and can also be used with active current sources.

Two relays and an active 0/4 mA to 20 mA current source are available as outputs. The relay contacts and the current output can be integrated into safety-relevant circuits. The current output is easily scaled.

On the built-in LCD display, the measured value can be indicated in various physical units. The unit is easily programmed via the keypad located on the front of the unit or with the PACTware™ configuration software. The input features a built-in line fault detection (LFD). A unique collective error messaging feature is available when used with the Power Rail system.

The device is designed for mounting on a 35 mm DIN mounting rail according to EN 60715.
