Description

The DM4391 is a loop powered isolator that provides an isolated 4-20 mA output proportional to a 4-20 mA input.

All operating power for the circuit is derived from the 4-20 mA input current.

The product is useful for breaking ground loops and for creating a 4-20 mA output in locations where primary power is not available.

A unique feedback system allows the DM4391 to achieve the same linearity as powered isolators and to drive loads from 0 ohms to 1000 ohms without affecting linearity.

The product is available as a single channel or a dual channel unit. The dual channel unit has two totally separate circuits that are fully isolated from each other.

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 in 4-20 mA current loops for isolation, buffering, noise reduction, especially where line power is NOT available.

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.
