The 6ES7322-1HH01-0AA0 is a digital output module belonging to Siemens’ SIMATIC S7-300 series, designed for industrial automation systems to control external electrical loads.
Key Features:
- Channel Configuration: Equipped with 16 digital output channels, enabling control of multiple devices simultaneously.
- Output Type: Uses relay outputs, which support both AC and DC loads—offering flexibility for connecting diverse industrial components (e.g., contactors, solenoid valves, or indicators).
- Electrical Specifications:
- Rated voltage range: Up to AC 250 V or DC 30 V.
- Maximum current per channel: 5 A (suitable for driving medium-power loads).
- Overload and short-circuit protection for enhanced reliability.
- Operational Design:
- Integrates LED status indicators for each channel, providing visual feedback on output activation (ON/OFF).
- Connects to the S7-300 backplane bus, enabling communication with the CPU without additional wiring.
- Requires an external load power supply (separate from the module’s logic power) to drive connected devices.
- Mechanical & Compliance:
- Mounts on the standard S7-300 DIN rail, with a compact design for space-efficient installation in control cabinets.
- Complies with global industrial standards (e.g., CE, UL) for safe operation in harsh environments.
Applications:
Ideal for controlling external actuators in factory automation, machine building, or process control—such as motors, valves, lighting, or alarm systems. It seamlessly integrates with S7-300 CPUs (e.g., CPU 312 to 319) to expand the system’s output capacity, supporting modular and scalable automation architectures.
This module is valued for its versatility (AC/DC compatibility via relays), robust protection features, and easy integration into S7-300 systems, making it a staple in industrial control setups.
