Information About 6ES7322-1HH01-0AA0
The 6ES7322-1HH01-0AA0 is part of the SIMATIC S7-300 SM322 relay output family, designed to offer electrically isolated switching for industrial automation environments. Its 16 relay outputs are arranged in two groups of eight, enabling independent isolation between output groups. The module supports both low-voltage DC and high-voltage AC loads, making it suitable for actuators such as solenoids, motor starters, lamps, and contactors. Relay isolation ensures safe operation while protecting the backplane and control electronics from electrical disturbances. Wiring is accommodated through a 20-pin front connector, and each channel includes a green LED status indicator. With robust electrical ratings, support for redundant load control, and compatibility with STEP 7 environments, this SM322 module provides dependable output control in S7-300-based systems.
Key Features:
- 16 Relay Outputs: Supports AC and DC loads up to 2A per channel.
- Dual Output Groups: Electrical isolation in two groups of eight channels.
- High Voltage Capability: Rated for 24V DC and up to 230V AC switching.
- Optical Isolation: Protects backplane and control circuits from interference.
- 20-Pin Front Connector: Simplifies wiring of actuators and field devices.
- Green Status LEDs: Visual indication for each output channel.
- Redundant Load Support: Parallel wiring allowed within the same output group.
- Wide Switching Spectrum: Supports resistive, inductive, mechanical, and lamp loads.
The 6ES7322-1HH01-0AA0 delivers the reliability and precision required for relay-based output control in Siemens S7-300 automation systems.
