The Siemens 6ES7222-1HF30-0XB0 is a SIMATIC S7-1200 SM 1222 digital output signal module with eight relay outputs arranged in groups of two. Each output can switch up to 2 A, with supported load voltages of 5 to 30 V DC or 5 to 250 V AC. The module consumes up to 120 mA from the 5 V backplane bus, uses approximately 11 mA per energized relay coil, and has a typical power loss of 4.5 W. Output switching delay is up to 10 ms, and the 6ES7222-1HF30-0XB0 supports mixed-load machine and process-control applications.

Switches contactors, solenoid valves, brakes, and auxiliary relays in S7-1200-controlled equipment.

Operates indicators, pneumatic valves, interlocks, and sequence outputs on packaging and assembly machinery.

Controls contactors, alarms, and auxiliary circuits in pumping, ventilation, and treatment skids.

Drives diverters, stops, warning devices, and relay-isolated loads on conveyors and transfer systems.

Provides dry-contact relay switching for compatible low-voltage DC and mains-rated AC control loads.

Restores SM 1222 relay-output capacity during exact-model replacement, retrofit, and maintenance.
