### 4. Functionality

The HSL-DI32-M-P functions as a discrete input expansion module within the ADLINK HSL distributed I/O system. It captures digital input signals from field devices such as sensors, switches, and pushbuttons, and transmits these signals to a host controller or PLC via the HSL communication bus.

Operating Principle:
- Each input channel detects a high (ON) or low (OFF) state based on the voltage level applied to the input terminal.
- The PNP sourcing configuration means that the input device sources current into the module’s input terminal when active.
- The module’s internal circuitry, including LED indicators, provides visual feedback for each channel’s status.
- The HSL communication interface transmits input data to the main controller at high speed, ensuring minimal latency.

Use Cases and Applications:
- Industrial automation and process control systems
- Machine control and monitoring
- Distributed I/O systems in manufacturing lines
- Data acquisition for digital sensors and switches
- Integration with PLCs, motion controllers, and SCADA systems

Compatibility:
- Fully compatible with ADLINK’s HSL system architecture
- Works with HSL terminal bases (HSL-TB32-U-DIN, HSL-TB64-DIN)
- Supports RS-422 communication standard for robust, noise-immune data transmission
