4. Functionality
The DI‑16(FIT) module functions as a distributed digital input interface within CONTEC’s F&eIT architecture. It converts 12–24 V DC discrete signals from field devices into logic‑level data accessible to host controllers or PCs via the F&eIT bus or Ethernet network.
Operation Principle:
Each input channel uses a photocoupler to isolate and detect the ON/OFF state of external devices. The module’s internal logic scans all inputs at high speed and transfers their status to the controller through the F&eIT bus. Interrupts can be generated for edge‑triggered events, enabling real‑time response.
Typical Applications:
- Monitoring limit switches, proximity sensors, and pushbuttons in production lines.
- Collecting digital status signals from PLCs or machine controllers.
- Integrating distributed I/O into SCADA or HMI systems via Ethernet.
- Remote facility monitoring and alarm systems.
- Laboratory automation and test equipment requiring isolated digital inputs.
Compatibility:
The DI‑16(FIT) connects directly to F&eIT controllers such as CPU‑CA20(FIT)GY (Ethernet I/O Controller), CPU‑SB20(FIT)GY (Micro Controller), or SVR‑MMF(FIT)GY (Monitoring & Control Server). It can also be used as an expansion module for USB‑based DI‑16(USB)GY units. Software access is provided through CONTEC’s API libraries or via socket communication using the F&eIT protocol.

Stacking Connection:
Modules interconnect laterally using the F&eIT bus connector. Align the stack hooks and press until locked. Up to eight modules can be stacked per controller, provided total current consumption does not exceed 3 A.
Wiring:
Use the supplied screw‑less plug for signal wiring. Strip 7–8 mm of insulation, press the orange release button, insert the wire, and release to clamp. Each common terminal serves eight input points. Observe polarity when connecting external 12–24 V DC supplies.
Power Supply:
The module receives 5 V DC from the controller via the stack connector. When used standalone with USB controllers, external 5 V DC power may be supplied through the front connector.
Configuration:
When connected to a controller, the DI‑16(FIT) is automatically recognized. Channel mapping and interrupt settings are configured through CONTEC’s setup utilities or API functions. No DIP‑switch configuration is required beyond the Device ID rotary switch (used when multiple identical modules are stacked).
7. Performance & Capabilities
