Signal Conditioner with Trip Amplifier DAT5028

General Description.

The DAT 5028 is a Signal Conditioner with 2 or 4 relay outputs (Trip Amplifier).

The DAT5028 Signal Conditioner also converts thermocouples, RTD's, potentiometers, voltage or current input to either a voltage 0-5V, 0-10V or 4-20mA, 0-20mA output.

With the aid of the local 4 digit display and the DIP Switches each trip point can be set by using the switches on the front panel.

The current input, output can be passive or active loop.

There is 1500 Vac Isolation between inputs, outputs and the power supply.
