Micro Innovation CAN-3AI/1AO-UI Profibus Module
The Micro Innovation CAN-3AI/1AO-UI 86 51 2244192 is a Profibus analog module with three analog inputs and one analog output. It is designed for voltage and current signals, allowing it to work with a wide range of industrial sensors and actuators. The module is used in automation systems where process values must be measured and controlled accurately.
Analog signals carry continuous information about temperature, pressure, flow, level, position, and other process values. Capturing these values reliably is essential for closed loop control, quality monitoring, and process documentation. The CAN-3AI/1AO-UI is built to perform this task in industrial environments where electrical noise and temperature variation are present.
Product Overview
The CAN-3AI/1AO-UI is a compact module for control cabinet mounting. Its three input channels support voltage and current signals, and its single output channel provides an analog command for actuators, valves, or drives. This combination makes the module suitable for control loops that require both measurement and output in one unit.
The module communicates over Profibus and can also be used in CAN based architectures. Measured values and output commands are transferred to the controller at a high update rate, so the control program always works with current data.

Measurement and Output
The input channels use analog to digital conversion circuitry that provides the resolution needed to detect small changes in the measured quantity. Filtering and shielding measures reduce the effect of electrical noise. Each channel is calibrated so that the digital value corresponds accurately to the input signal.
The output channel provides a configurable analog signal for controlling actuators. Scaling is configured in the engineering environment so that the output value corresponds to the required engineering units.
Applications
The module is used in process systems, packaging machinery, material handling equipment, and environmental control. In process systems, it reads temperature sensors, pressure transmitters, and flow meters and controls valves or dampers. In packaging, it monitors sealing temperature and film tension. In material handling, it measures load and position.
Because the module supports both voltage and current signals, it can be used with a wide range of industrial sensors. This makes it a flexible choice for machine builders who work with different measurement technologies.
System Integration
Integration begins with mounting the module and connecting the sensor and actuator wiring to the terminals. The network links the module to the controller, which recognizes the device and makes its channels available in the programming environment. Engineers assign symbolic names and scaling values to each channel.
Diagnostic information helps identify sensor and wiring problems. If a channel reports a value outside the expected range, the technician can check the sensor, the cable, and the module in a logical order.
Installation Notes
Correct installation improves measurement quality. Analog signal cables should be shielded and routed away from power cables. Shields should be connected according to the system guidelines, and the module should be mounted with sufficient clearance for air circulation.
Maintenance
The module has no moving parts, so maintenance is mainly preventive. Terminal connections should be checked periodically, and dust should be removed from the module surfaces. If a channel drifts or fails, the diagnostic data helps determine whether the sensor, the wiring, or the module is responsible.
