Siemens 6ES7222-1HH32-0XB0 S7-1200 SM 1222 16DO Relay

Siemens SIMATIC S7-1200 SM 1222 digital output module provides 16 relay outputs with 2A per channel. Relay outputs with group isolation between channels, suitable for direct switching of low-power AC/DC loads within rated limits. Widely used in machine automation, conveyor systems, packaging equipment, and process control panels requiring multiple relay outputs.

Applications:

• Switching of pumps, fans, and small motors

• Actuation of solenoid valves and contactors

• Control of indicator lamps and alarms

• Interfacing with AC or DC loads up to 2A

• Expansion of S7-1200 output capacity for relay-based circuits

Technical Specifications:

• Number of outputs: 16 relay outputs (Form A, normally open)

• Output current: 2A per channel (resistive), 0.5A (inductive, typical)

• Load voltage: 5V to 230V AC / DC

• Isolation: Relay outputs with group isolation between channels

• Switching time: Approx. 10 ms (operate), 10 ms (release)

• Service life (mechanical): Approx. 10 million cycles

• Service life (electrical): Depends on load type and switching conditions (typical up to 100,000 cycles at rated load)

• Supply voltage: 24V DC from backplane bus
