### 4. Functionality

The HSL-DO32-M-N functions as a discrete output expansion module within the HSL (High Speed Link) distributed I/O system. It receives digital output commands from a host controller or HSL master module via an RS-422 communication interface. Each of the 32 output channels can independently switch external loads by sinking current to ground, making it ideal for controlling devices that require NPN-type outputs.

Typical Use Cases:
- Industrial automation control systems
- Machine tool control and monitoring
- Process automation and factory equipment
- PLC and motion control system expansion
- Signal output for alarms, indicators, and actuators

Operation Principle:
Each output channel uses an NPN transistor that connects the load to ground when activated. The external load is powered by an external DC supply (10–30 V), and the board’s outputs sink current to complete the circuit. The board’s internal circuitry ensures isolation and protection for each channel, while LED indicators provide real-time visual feedback of output states.

Compatibility:
- HSL-TB32-DO-DIN: 32-channel terminal base specifically for NPN sinking outputs.
- HSL-TB32-U-DIN: Universal 32-channel terminal base for general use.
- HSL-TB64-DIN: 64-channel terminal base supporting dual-slot configurations (Slot I / Slot II).
