Product details

Module identity & key ratings

The Siemens 6ES7222-1BH30-0XB0 is a 16-point digital output module for the SIMATIC S7-1200 family, rated 24 V DC and 0.5 A per output resistive or inductive. Diagnostic alarm and status feedback are built-in, but short-circuit protection must be added externally – the module itself provides none.

The 0.5 A per channel is a per-output limit, not the sum. At 55 °C horizontal or 45 °C vertical you can still source the full 0.5 A from each of the 16 outputs – no global derating until ambient exceeds those thresholds. Response times are sharp: 50 µs turn-on, 200 µs turn-off, which suits solenoid banks and relay coils operating below 50 Hz. At 24 V DC the module draws 2.5 W typical from the backplane – budget that in your 24 V supply sizing.

Mounting & wiring notes

The module is 45 × 100 × 75 mm, mounts on the DIN rail, and requires a front connector. Unshielded cable runs up to 150 m; shielded up to 500 m.

Frequently asked questions

Will the 6ES7223-1BL32-0XB0 drop in without rewiring?

No. That is a combined 16-input/16-output module with a different pinout and channel count. Replacing the 16DO module with the combined version requires rewiring the connector and reconfiguring the I/O in the PLC program.

What are the maximum and minimum operating temperatures?

The module operates from –40 °C to 70 °C ambient. For horizontal mounting the maximum is 55 °C; for vertical mounting it derates to 45 °C.

Does the module have short-circuit protection?

No. Short-circuit protection must be provided externally – typically a PTC or miniature circuit breaker on each output group.
