### 4. Functionality

The HSL-DI16DO16-M-NN functions as a distributed I/O module within ADLINK’s HSL network. It interfaces discrete field signals (sensors, switches, actuators, relays) with a host controller or PLC via high-speed serial communication.

Operational Principle:
- Inputs: Each of the 16 input channels detects the ON/OFF state of external NPN-type sensors or dry contacts. The input circuitry includes internal pull-up resistors and LED indicators for channel status visualization.
- Outputs: The 16 transistor outputs drive external loads such as relays, solenoids, or indicator lamps. Each output channel operates as an NPN sinking output, switching the load to ground when activated.
- Communication: The module exchanges I/O data with the HSL master controller through RS-422 differential lines, ensuring reliable, noise-resistant communication over long distances.
- Addressing: A 6-bit DIP switch allows the user to assign a unique address (1–63) to each module, enabling multiple modules to coexist on the same HSL network.

Typical Applications:
- Factory automation and process control
- Machine tool monitoring and control
- Packaging and assembly line systems
- Distributed I/O expansion for PLCs and motion controllers
- Industrial equipment requiring fast, deterministic digital I/O
