Product details

The Siemens 6ES7223-1BL32-1XB0 is a 16-input digital I/O module for the S7-1200 system, operating on 24 VDC. Approval stack includes UL, CSA, FM, Marine (DNV/GL), KC, CE, and RCM — enough to satisfy global panel certifications without extra paperwork.

Expect full compliance paperwork: RoHS, REACH, UL file, CSA report, FM certificate, Marine type approval, and CE declaration. The housing is plastic (IP20), rated fall height 0.3 m.

Physical and electrical integration

Input thresholds: signal '1' at 15 VDC, 2.5 mA; signal '0' at 5 VDC, 1 mA. Unshielded cable runs up to 150 m; shielded up to 500 m. Switching delays: 0→1 in 20 µs, 1→0 in 350 µs. Derating note: up to 40 °C, the module can handle 16 inputs at full rated current; at 50 °C, current per input drops to 8 A. Keep that in mind for warm panels near the top of the temperature range.

Frequently asked questions

What compliance certifications does this module carry?

It holds UL, CSA, FM, Marine (DNV/GL-type), KC, CE, and RCM approvals. That covers most global panel certification requirements.

Will this module drop into a panel designed for the 6AG1223-1BL32-4XB0?

The 6ES7223 and 6AG1223 variants share the same form factor and electrical interface. The 6AG is a ruggedized SIPLUS version; the standard module fits the same rail and wiring, but confirm your ambient temperature and coating requirements against the standard module's specs.
