+86 15359408275SIMATIC S7-1200 SM 1222 16-Relay Output Module · Siemens SIMATIC S7-1200 SM 1222
Siemens 6ES7222-1HH30-0XB0 is a SIMATIC S7-1200 SM 1222 digital output module with sixteen electromechanical relay channels.
Each relay output can switch a documented resistive load up to 2 A, while the installation must provide suitable branch protection because the outputs do not include electronic short-circuit protection.
Before replacement, record every output address and load type, AC or DC switching voltage, steady-state and inrush current, external fuse, common wiring, suppression device, safe-state requirement, relay duty cycle and TIA Portal hardware configuration.
| Manufacturer | Siemens |

| Maximum resistive-load current | 2 A per output |
| DC load-voltage range | 5-30 VDC |
| Backplane current at 5 VDC | 135 mA maximum |
| Relay-coil load current | 11 mA per relay |
| Typical power loss | 8.5 W |
| Short-circuit protection | External protection required |
| Lifecycle status | Discontinued / spare-part reference |
Siemens 6ES7222-1HH30-0XB0 adds sixteen relay digital outputs to a compatible SIMATIC S7-1200 station for switching approved AC or DC loads.
Each Siemens 6ES7222-1HH30-0XB0 relay output is rated for a maximum 2 A resistive load, but inductive inrush and contact-life requirements may require a lower application current.
Siemens 6ES7222-1HH30-0XB0 does not provide electronic short-circuit protection at the relay contacts, so correctly sized external protection is required.
Siemens 6ES7222-1HH30-0XB0 can switch only loads within the documented relay ratings, and coils or contactors require approved suppression and an inrush and contact-life review.
A transistor-output module cannot directly replace Siemens 6ES7222-1HH30-0XB0 because voltage, polarity, leakage, switching speed, current and isolation behavior differ from relay contacts.
Commission Siemens 6ES7222-1HH30-0XB0 by proving each output address and safe state, measuring load voltage and current, checking fuses and suppression and monitoring relay operation under the actual load.
Provide the complete Siemens 6ES7222-1HH30-0XB0 label, hardware revision, load-voltage schedule, current and inrush data, external protection, quantity and destination.
Send the complete 6ES7222-1HH30-0XB0 catalog number, revision, quantity, destination and nameplate photo. Identification details will be checked before quotation.
