Intrinsic safety & signal conditioning

Transmitter power supply with trip point relays

This signal conditioner provides the isolation for non-intrinsically safe applications.

The device supplies 2-wire and 3-wire transmitters, and can also be used with 2-wire current sources.

It transfers the analogue input signal as two isolated current values.

Both outputs provide a 0/4-20mA current corresponding to the input signal. The minimum available field voltage is 16V at 20mA.

If necessary, the internal resistance of 250Ω between terminals 8, 9 and 11, 12 can be used for conversion into a 0-5V voltage signal.
