### 4. Functionality

The DIN-96DO-01 functions as an isolated digital output interface board that connects to a host controller or data acquisition card (such as the ADLINK PCI-7396) via a 100-pin SCSI-II cable. Each of the 96 output channels is optically isolated from the control circuitry, ensuring that electrical noise, surges, or ground potential differences in the field wiring do not affect the host system.

Working Principle:
- The board receives digital output signals from the host controller through the SCSI-II interface.
- Each signal drives a Darlington transistor pair, which acts as an open-collector switch.
- When activated, the transistor sinks current from the external load connected to the output terminal, allowing control of external devices such as relays, solenoids, or indicator lamps.
- Optical isolation between the input logic and output circuitry ensures safe and reliable operation even in electrically noisy environments.

Use Cases and Applications:
- Industrial automation and process control systems
- Machine control and equipment interfacing
- PLC and SCADA system expansion
- Relay and actuator control
- Signal switching and load driving in test benches
- Factory monitoring and distributed I/O systems

Compatibility:
- Fully compatible with ADLINK PCI-7396 and other 96-channel digital I/O cards using a 100-pin SCSI-II interface.
- Can be integrated into systems requiring high-density digital output expansion with optical isolation.
