MPN: 1746-OB16 — industrial control spare part, in stock at TGK Parts.
The 1746-OB16 provides 16 DC sourcing outputs (10–50 V) per SLC 500 slot for solenoid valves, contactors and indicator banks. Short-circuited field wiring is the usual killer — output drivers are sacrificed to protect the backplane. Each unit we ship has every output loaded-tested with a real resistive load, not just a LED check.
Available new surplus and tested used; the -OB16E revision is also sourced on request.

Replacement and spare part for industrial automation equipment — production lines, CNC machines, packaging machinery, textile machinery, printing equipment and more.
Yes — 24 VDC solenoid valves are the standard load; verify total current per group.
A welded driver usually means field short damage. We test all outputs under load; repair is sometimes possible.
The E revision adds extended diagnostics/current capability; send your nameplate and we match it.
