Product details

The 6ES7922-5BC50-0AB0 is a pre-wired front connector for SIMATIC S7-1500 digital I/O modules — 40 poles on the module side, broken out to 20 individual single cores (H05V-K, 0.5 mm²) with screw-type terminals on the field end. The 2.5 m cable length gives enough reach to a nearby DIN-rail terminal block without coiling excess inside the enclosure.

Rated 24 V with a maximum of 30 V — this matches the standard S7-1500 backplane supply for digital I/O. The 40-pole connector mates with the 6ES7592-1AM00-0XB0 module-side receptacle (not included). The 20 cores are numbered 1–20, with the white adapter contact marking the core number; the remaining 20 poles on the module side are not wired out, so this variant is intended for 20-channel digital I/O modules where you only need one signal per channel (no return or shield termination through the connector).

Frequently asked questions

What is the maximum voltage rating on this front connector?

The maximum rated voltage is 30 V, with a nominal rated value of 24 V — standard for S7-1500 digital I/O backplane supply.

Where can I buy 6ES7922-5BC50-0AB0 and how is it quoted?

This part is sourced and quoted to order against an RFQ through independent distribution channels. Availability and current pricing are confirmed at the time of quote.

Will 6ES7922-5BC50-0AB0 drop into a panel specified around 3RH2122-1WB40?

No — the 3RH2122-1WB40 is a SIRIUS coupling relay with screw and snap-on DIN-rail mounting, a completely different form factor and function. The 6ES7922-5BC50-0AB0 is a pre-wired front connector for SIMATIC S7-1500 I/O modules and does not share a mounting footprint or wiring scheme with that relay.
