### 4. Functionality

The HSL-DI32-DB-N functions as a discrete input interface module within the HSL distributed I/O system. It captures digital signals from field devices such as sensors, switches, and relays, and transmits them to the HSL controller via high-speed RS-422 communication lines.

Operating Principle:
- Each of the 32 input channels detects the ON/OFF state of an external NPN sinking or dry contact device.
- The board converts these signals into digital data, which is then transmitted over the HSL bus to the host controller.
- The module occupies two consecutive address allocations within the HSL network, starting from an odd-numbered address. DIP switch bit 1 is fixed to ON for address configuration.

Use Cases and Applications:
- Industrial automation and process control systems
- Machine tool monitoring and control
- Packaging and assembly line automation
- Factory data acquisition systems
- Distributed I/O expansion for PLCs and motion controllers

Compatibility:
- Designed for use with HSL-TB32-U-DIN (32-channel terminal base) and HSL-TB64-DIN (64-channel terminal base).
- Compatible with other HSL modules and controllers within ADLINK’s HSL ecosystem.
