Signal Conversion

The SM 1222 digital output signal modules convert the internal signal level of the SIMATIC S7-1200 Controller into the external signal level required for the process. This ensures seamless integration between the controller and field devices.

Applications

Perfect for industrial automation systems requiring compact digital output control including:

• Small motor control and actuation
• Valve and solenoid operation for lighter loads
• Indicator lights and status displays
• Process control equipment
• Compact manufacturing automation systems
• Building automation applications

Compatibility

Designed for seamless integration with SIMATIC S7-1200 controller systems (except CPU 1211C) and compatible with TIA Portal programming environment. The fine-granular design approach saves space in control cabinets and optimizes hardware costs.
