### 4. Functionality

The HSL-R8DI16-M-P serves as a distributed I/O interface within an HSL-based automation network. It connects to a host controller or master module via RS-422 differential communication lines, enabling high-speed data transfer and deterministic control.

Operation Principle:
- Input Function: The 16 PNP sourcing input channels detect the ON/OFF status of external sensors, switches, or proximity detectors. Each input channel sources current to the connected device, providing reliable signal acquisition.
- Output Function: The 8 relay output channels control external actuators such as solenoids, contactors, or indicator lamps. Each relay output can switch DC or AC loads, providing electrical isolation between control logic and field devices.
- Communication: The module exchanges I/O data with the HSL master through high-speed serial communication, ensuring synchronized updates across the network.
- Addressing: DIP switches on the board define the module’s address within the HSL network. The addressing scheme allows consecutive address allocation for multiple modules.

Applications:
- Factory automation and process control
- Machine tool control and monitoring
- Packaging and material handling systems
- Distributed I/O for PLC and PC-based control systems
- Building automation and environmental monitoring

Compatibility:
- Fully compatible with ADLINK HSL terminal bases:
