AC/DC & DC/DC Opto-Isolators

The Ringway ISOPLC Series of Opto-Isolators are designed to allow the isolated monitoring of low voltage AC signals (100-250V) or Extra low voltage DC (24-50V) signals using standard DC PLC inputs. The isolators work by switching their output to the PLC on while an input signal is present. The Isolator output to the PLC may be wired as either a sou...

Features

Simple, robust and functional.
Flexible input voltage range
Quick, easy & safe way of monitoring AC and DC points into DC PLC inputs.
LED Indicator provides visual status feedback.
LED Indicator wired in series with output to PLC reduces false status indication failures modes, common to other general purpose isolators.

Applications

The Ringway ISOPLC Series Isolators allows for the easy connection and or monitoring of circuits with a low voltage (safe) DC PLC input. Applications include:

Monitoring control circuit voltage into PLC for detection of control voltage failure and / or cross interlocking of system faults.

Retro-fit monitoring and/or control to older circuits where it is not easy or economically viable to convert to DC control.
