Description

The DM4380A provides a DC output proportional to a DC input. The output is fully isolated from input, line power, and ground. The unit is useful in eliminating ground loops and common mode signals.

Input and output ranges are user-settable. Each may be voltage or current, with or without offset. The output response may be normal or reverse-acting. A fully-labeled set of jumpers selects the input and output ranges.

The DM4380A includes filtering and conditioning to reduce susceptibility to transients and noisy operations. It utilizes a feedback VCO to develop a pulse train with a duty cycle proportional to the input signal amplitude. This pulse train is coupled through a pulse transformer to the output circuitry, where the duty cycle data is converted to a proportional DC output level.

Connections are made via two 4-pin plug-in terminal blocks. These terminal blocks allow the product to be removed without unwiring
the connections.

Typical Applications

Eliminates ground loops and common mode signals for voltage/current scaling or conversion, isolation, buffering, noise reduction. Single-unit replacement module provides all normal input and output ranges.

Mounting

The module mounts on a standard H-35 DIN rail. A spring latch holds it in place. The module is demounted by using a screw driver to release the latch at the bottom of the module.
