I/O Breakout and Optical Isolation The general purpose I/O boards from your favourite automation supplier are an ideal method of interfacing external switches and indicators to your system. Designed to be embedded in a console or other packaged solution however, their compact form factor and ribbon cable connections are not ideally suited to rack mounting and field wire terminations. Further, these I/O boards are often not designed to handle the stray static and EMI voltages that can be introduced by lengthy field wiring.
Our breakout boards solve both of these problems. Pluggable Phoenix-style connectors make field wiring a breeze, and built-in optical isolation circuitry prevents dangerous field wiring voltages from damaging the sensitive electronics on the manufacturer’s I/O board.Additional features include programmable lamp current limiting via socketed resistor packs, and provision for connecting a secondary external lamp voltage.
