- Digital Input Function: The additional digital input channels allow monitoring of discrete signals such as switches, relays, or logic-level outputs from external devices.
- Integration with AIO-161601: The board connects directly to the AIO-161601 main board via a compatible interface, extending the total input capacity without requiring additional PCI slots.
- Applications:
- Industrial process monitoring and control
- Data acquisition in laboratory environments
- Automated test systems
- Embedded measurement systems
- Sensor array integration and signal conditioning setups
- Compatibility: Fully compatible with Contec’s AIO-161601 series hardware and associated software drivers. It can be used in systems running standard operating systems supported by Contec’s driver suite (e.g., Windows, Linux).
