### 4. Functionality

The HSL-DI8DO8-C-NN functions as a discrete I/O interface module within an HSL-based distributed control system. It provides eight digital input channels for receiving signals from field sensors, switches, or other NPN-type devices, and eight digital output channels for driving actuators, relays, or indicators.

Operational Principle:

- Inputs: Each input channel detects the ON/OFF state of an external NPN sinking signal or dry contact. The internal circuitry includes a pull-up resistor and LED indicator for each channel, allowing visual confirmation of input status.
- Outputs: Each output channel operates as an NPN sinking driver, capable of switching external loads connected to a positive voltage source. The outputs are transistor-based, providing fast switching and long operational life.
- Communication: The board communicates with the HSL master controller via RS-422 differential signaling, ensuring noise immunity and reliable data transmission over long distances.
- Addressing: DIP switches on the board allow users to assign module addresses within the HSL network. Each module occupies consecutive address spaces, enabling flexible system configuration.

Typical Applications:

- Industrial automation and process control
- Machine tool monitoring and control
- Packaging and assembly line automation
- Material handling systems
- Building automation and facility management
- Distributed I/O expansion for PLCs and motion controllers

Compatibility:

- Fully compatible with ADLINK HSL terminal bases:
