DESCRIPTION

The DR4300 provides an isolated DC voltage or current output proportional to a DC voltage or current input. The input and output are ranged at the factory, but Zero and Span controls provide ±15% adjustability.

The DR4300 provides 3 way isolation between input, output, and power source.

The isolation makes the product useful for measuring input signals with high common mode voltages and for breaking ground connections to eliminate ground loops. Its wide choice of inputs and outputs allow signal conversion and scaling as well.

The screw terminal blocks plug into the case, which allows easy wiring and removal of products.

All of the DR Series of products provide transient protection to help eliminate damage from lightning and from other transients created on the power and signal leads.

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

All DR Series products are designed to mount on a 35 mm DIN rail. The products feature a steel mounting clip, with a compression spring, for secure mounting.
