MICRO INNOVATION AG WINBLOC CAN-4AI/UI Analog Input Module

The MICRO INNOVATION AG WINBLOC CAN-4AI/UI Analog Input Module is an analog input unit for industrial automation. It is part of the WINBLOC CAN I/O family and provides four analog input channels. The UI designation indicates that each channel can accept voltage or current signals, making the module flexible for different sensors and measurement devices. It communicates over CAN and supports distributed installation close to the process.

Analog Input Function

The module acquires analog signals from sensors such as pressure, temperature, flow, position, and level transmitters. Each channel can be configured for voltage or current input to match the connected device. Signal conditioning and filtering help improve measurement stability and reduce noise. The analog values are converted into digital data and made available to the controller. This supports precise process monitoring and closed loop control in machines that require variable measurement.

CAN Communication

The module communicates over the CAN network. It exchanges analog input data, status information, and diagnostic messages with the controller. CAN communication supports distributed architectures and reduces long cable runs to the central cabinet. Correct bit rate, termination, and cable routing are important for reliable operation. The module can be combined with other WINBLOC CAN modules to create a scalable I/O system. This helps machine builders adapt the control system to different machine sizes and process requirements.

Configuration

Configuration is performed within the appropriate engineering environment. Channel range, input type, scaling, and filtering can be adjusted to match the connected sensors. Each input can be assigned a signal name and engineering unit for clear documentation. The module address and network settings must match the system design. After configuration, analog values should be tested to confirm correct wiring and scaling.

Diagnostics

Diagnostic functions help users monitor module status and analog channels. The module can report signal overrange, underrange, wiring faults, communication errors, and module faults. Status indicators provide local information during commissioning and service. Diagnostic data can be displayed on an HMI or evaluated by the controller. This supports fast troubleshooting and reduces downtime. Regular inspection of terminals and shielded cables helps maintain reliable measurement.

Installation

The module should be installed in a suitable control cabinet or enclosure with protection from dust, moisture, and excessive heat. DIN rail mounting is typical for WINBLOC modules. Analog signal cables should be shielded and separated from power cables to reduce interference. Grounding should follow the system manual. Power supply connections must be made according to the module rating. The base included with the module supports secure mounting and wiring. After installation, functional tests should confirm that all channels operate correctly.

Applications

The MICRO INNOVATION AG WINBLOC CAN-4AI/UI Analog Input Module is suitable for packaging, assembly, handling, injection molding, process control, and general machine automation. It is especially useful where analog sensors must be monitored and where distributed I/O is required. Machine builders can use the module to create flexible measurement solutions with clear diagnostics and scalable expansion.

Conclusion

The MICRO INNOVATION AG WINBLOC CAN-4AI/UI Analog Input Module provides reliable analog signal acquisition for CAN based automation. It supports four voltage or current channels, distributed installation, diagnostics, and integration with WINBLOC systems. When installed and configured correctly, it contributes to accurate process monitoring and maintainable machine control.
