### 4. Functionality
The MezIO-D230-12 functions as an isolated digital I/O expansion module that interfaces external digital signals with the host embedded controller. It provides both input and output capabilities, enabling the system to monitor external sensors and control actuators or other digital devices.
How It Works:
- Digital Input Function:
Each of the 16 input channels detects the logic state (high or low) of external digital signals. The optical isolation ensures that voltage fluctuations or electrical noise from external devices do not affect the host system. The module can operate in Polling Mode, where the system continuously reads input states, or Change-of-State Mode, where the module reports only when an input changes, reducing CPU load.
- Digital Output Function:
The 16 output channels can drive external loads such as relays, LEDs, or solenoids. Each channel can sink up to 500 mA at 24 VDC, allowing direct control of moderate-power devices. The isolation barrier protects the system from back-EMF or transient voltages generated by inductive loads.
Use Cases and Applications:
- Industrial automation and process control
- Machine status monitoring and control
- Factory equipment interfacing
- Building automation systems
- Test and measurement systems
- Embedded control in transportation or energy systems
Compatibility:
- Fully compatible with Neousys POC-120 series embedded controllers
