4. Functionality
The PCM-7230+ functions as a digital input/output interface module for embedded and industrial control systems. It connects directly to sensors, switches, and actuators, enabling the host system to monitor and control external devices.

- Digital Input Function: Each of the 16 input channels can detect the ON/OFF status of external digital signals. The optical isolation ensures that high-voltage transients or ground potential differences do not affect the system logic.
- Digital Output Function: The 16 output channels can drive external loads, such as relays, solenoids, or indicator lamps. The isolation barrier protects the host system from load-induced voltage spikes.
- Signal Isolation: The 2500 Vrms isolation barrier separates field wiring from the system bus, preventing electrical noise or surges from damaging the host computer.
- Use Cases:
- Industrial automation and process control
- Machine monitoring and control systems
- Embedded data acquisition systems
- Test and measurement equipment
- Transportation and mobile control systems
- Energy management and building automation
- Compatibility: Fully compatible with PC/104+ stackable systems, allowing integration with CPU modules, communication cards, and other I/O boards.
