Siemens SM 322 RELAY 6ES7 322 1HH01 0AA0 DIGITAL OUTPUT DO MODULE

The Siemens SM 322 Relay output module (6ES7 322-1HH01-0AA0) is a digital output module designed for use with Siemens S7-300 series programmable logic controllers (PLCs). It provides relay outputs that can switch higher current loads than transistor outputs, making it suitable for controlling various industrial devices such as motors, valves, and other actuators.

Key Features:

1. Relay Outputs: Provides relay contacts for switching external devices on and off.
2. Number of Outputs: Typically offers 16 relay outputs in a single module configuration.
3. Contact Configuration: Each relay output typically includes a single-pole double-throw (SPDT) contact configuration (Form C).
4. Load Capacity: Capable of switching higher currents compared to transistor outputs, suitable for loads that require higher power handling.
5. LED Indicators: Status indicators for each output channel provide visual feedback on the output status.
6. Compatibility: Designed for use with Siemens S7-300 series PLCs, ensuring seamless integration and compatibility with the system.
