DESCRIPTION

The DR4302 provides two individually isolated DC outputs, proportional to a DC input, with 4 way isolation between input, power, and outputs. The unit is useful in eliminating ground loops and measuring signals with large common mode voltages.

All of the DR Series of products provide transient protection to help eliminate damage from lightning and from other transients coupled onto the power and signal leads by system wiring.

TYPICAL APPLICATIONS

Provides isolation between field instrumentation and control room. Use for reducing noise created by ground loops. Also use for signal conversion (voltage to current) and increasing drive capacity.

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.
