I/O and communication modules are the parts a maintenance store should hold and usually does not. When one fails, the catalogue number is exact and the alternatives are none.

Communication modules are the critical spares

A 1756-EN2T failure takes an entire rack off the network, which is why it is the most traded Rockwell part in existence. The same applies to DeviceNet scanners and DH+ bridges on legacy systems.

Connection count and firmware revision both matter. An EN2T at an older revision may not support the connection count your application needs, and we report the revision on every module.

Check what is physically included

Removable terminal blocks are separate part numbers and are frequently missing from surplus modules. So is the keying on the chassis. Neither is expensive, but discovering it during a shutdown is.

Every listing states whether an RTB is included. If you need modules with terminal blocks fitted, say so on the request and we will quote them as a set.

Common questions

Are removable terminal blocks included?

Only where stated. RTBs are separate part numbers and often absent from surplus stock, so we list them explicitly.

Can you test a module in my configuration?

We test in a live chassis. If your application depends on a specific firmware revision or connection count, tell us and we will verify against it.

Do you stock legacy SLC and PLC-5 I/O?

Yes, and it is a category where surplus is often the only source. Send the catalogue numbers and we will check current stock.
