What Total Discontinuation means for you

The manufacturer has finished with the part. You may still find one through surplus or refurbished sellers, or in another site's stores, but that is not a supply chain. Knowing where your units are, and where a spare might be, is what shortens the stoppage when one fails.

Before replacing an input module

For an input module we would record the field voltage, sink/source arrangement, commons, channel allocation and PLC addresses before considering an alternative.

Modern I/O can accept the same nominal signals but use different terminal layouts, isolation groups or addressing, which means a small module change can create wiring and software work. Photographing the terminations and exporting the I/O configuration now can save a lot of diagnosis during a breakdown.
