Description

The DM4003 provides an isolated voltage or current output proportional to the position of a potentiometer wiper.

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. The output response may be normal or reverse-acting. A fully-labeled set of jumpers selects the input and output ranges.

The DM4003 includes selectable 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

A useful interface for monitoring valve and actuator position, or for generating test signals.

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 screwdriver to release the latch. The latch release is accessible at the bottom of the module.
