### 4. Functionality
The TB‑16P8R/12 acts as an interface board between field devices and ADLINK digital I/O cards. It provides electrical isolation for input signals and relay switching for output control.
Operation Principle
- Input Channels: Each input signal is fed through a photo‑coupler (opto‑isolator) that transfers the signal to the logic side without direct electrical connection. This protects the host system from voltage spikes and ground potential differences.
- Output Channels: Each relay output is driven by a control signal from the connected I/O card through the Opto‑22 interface. The relay contacts can switch external loads such as solenoids, lamps, or contactors.
- LED Indicators: Each channel has a dedicated LED that illuminates when the channel is active, providing instant visual feedback for diagnostics and monitoring.

- Industrial automation and process control systems
- Machine status monitoring and signal isolation
- Relay control for motors, valves, and actuators
- Data acquisition and test systems requiring isolated I/O
- Interface between PLC logic levels and field devices
