The 1746-OB32E has been cancelled (since December 2022): no longer sold as a current product, though spares may remain available for a period.

What Cancellation means for you

You can no longer order it as a normal product, and nothing new should be designed around it. If machines depend on it, you want spare stock you can rely on and a migration plan. Both start with knowing how many you run.

Before replacing an output module

Output modules need a load-by-load check rather than a simple channel-count comparison. We would confirm whether each point is switching relays, solenoids or other loads, the current requirements, common arrangements and any interposing devices.

Those details determine whether a proposed replacement behaves electrically like the original and whether PLC logic or wiring must change. A documented output schedule is particularly valuable if the original module fails before a migration is planned.
