4-20mA Sensor Interface Breakout Box
Models: PRO Series, D4+, D4 Premium, E4+, F4+, G+, H+, J+, K+
Overview
The 4-20 mA UV sensor interface unit allows the UV sensor current to be accessed and monitored by an auxiliary device so that
remote monitoring can be achieved. The unit must be terminated with a resistor so that the loop current is maintained and not
broken. Connection to the loop is done by connecting the termination wires to the terminals marked + and - and securing the wires
with the brass thumb nuts.
