MPN: 1746-IB32 — industrial control spare part, in stock at TGK Parts.
The 1746-IB32 packs 32 sinking 24 VDC inputs into a single SLC 500 slot — the high-density choice for machine tool I/O and conveyor control where panel space is tight. Input circuits fail from miswired field voltage (typically 110/230 VAC landed on a DC input), which is why used 1746-IB32 modules must be tested point by point.
We energize every input channel on the bench with a 24 VDC source and verify LED indication and backplane logic mapping before shipping.

Replacement and spare part for industrial automation equipment — production lines, CNC machines, packaging machinery, textile machinery, printing equipment and more.
Yes — usually a blown group fuse or opto-isolator damage from field overvoltage. We test all 32 points individually.
Yes, the SLC 500 rack accepts any 1746 I/O mix within power budget; check backplane current totals.
The 1746-ITB16 or -ITB32 terminal block is ordered separately; we can source both together.
