### 4. Functionality

The HSL-DI16DO16-M-NP functions as a distributed I/O expansion module within ADLINK’s HSL system. It provides a high-speed, deterministic interface between a host controller and field-level devices such as sensors, switches, relays, and actuators.

Working Principle:

- Inputs (NPN Sinking): Each input channel detects the presence of a low-level signal (sinking current to ground). The input circuit includes a 4.7 kΩ resistor and LED indicator for visual feedback.
- Outputs (PNP Sourcing): Each output channel sources current to connected loads, providing +24V DC when activated. The transistor-based output circuit ensures fast switching and electrical isolation.
- Communication: The board communicates with the HSL master via RS-422 differential lines (TX+/TX−, RX+/RX−), ensuring noise-resistant data transmission.
- Addressing: A 6-bit DIP switch allows configuration of up to 63 unique device addresses, enabling multiple modules on a single HSL network.

Applications:

- Factory automation and process control
- Machine tool control systems
- Packaging and material handling equipment
- Distributed I/O in PLC-based systems
- Sensor and actuator interfacing in industrial networks

Compatibility:

- Fully compatible with ADLINK HSL terminal bases:
- HSL-TB32-DIN
- HSL-TB32-U-DIN
- HSL-TB64-DIN
- Integrates seamlessly with HSL master modules and controllers supporting RS-422 communication.
