Wilkerson Instrument DR4302 Data sheet

DR4302

DUAL OUTPUT
ISOLATED TRANSMITTER (SPLITTER)

FEATURES

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
