Product details

The Siemens 6ES7222-1BH32-0XB0 is a 16-channel digital output module for the S7-1200 controller family. Each channel switches 24 V DC at up to 0.5 A resistive load, covering solenoid valves, pilot lamps, and small contactor coils. No onboard short-circuit protection is provided – fuse each group externally as the panel design dictates. The module requires a front connector (ordered separately) and reports diagnostic alarms for faults like wire break or blown fuse. Temperature range spans -40 to 70 °C, so this module works in freezer applications, paint booths, or unheated enclosures without derating. Vertical mounting extends the min to -20 °C, still plenty for most wash-down zones. Approvals cover cULus, CSA, FM, marine, KC, and RCM – one SKU that clears the compliance gate for most projects without relabeling.

Width 45 mm, height 100 mm, depth 75 mm. Backplane supplies 24 V DC; draws 2.5 W typical. Cable max: unshielded 150 m, shielded 500 m. IP20 – inside enclosure only.

Frequently asked questions

What's the difference between 6ES7222-1BH32-0XB0 and 6ES7223-1BL32-0XB0?

The 6ES7223 combo module adds 16 digital inputs alongside 16 outputs. The 6ES7222 is pure output only – it cannot read field devices. The wiring and I/O mapping are completely different.

Does this module include short-circuit protection?

No, external short-circuit protection must be provided – typically a fast-blow fuse or electronic circuit breaker per group of outputs.

What approvals does this module carry?

cULus, UL, CSA, FM, marine (DNV/GL/Lloyd's), KC, CE, and RCM. Suitable for global machine builds and shipboard panels.

Can I use this module in a cold storage application?

Yes, rated down to -40 °C operating. The vertical mounting limit is -20 °C, so orientation matters if the panel experiences extreme cold.
