Why Choose the Unitronics IO-AI8 Analogue Input Module?
The Unitronics IO-AI8 is a high-resolution analogue input expansion module designed for use with Unitronics Vision series PLC controllers. It enables PLC systems to capture multiple analogue signals from sensors and process instrumentation, supporting accurate monitoring in industrial automation environments.
The module provides eight independent analogue input channels, allowing integration of common industrial signals including 0–10 V, 0–20 mA and 4–20 mA. Each input can be configured for voltage or current measurement using jumper settings and PLC software configuration, enabling flexible system integration.
Designed for reliable factory operation, the IO-AI8 offers 14-bit analogue resolution for precise signal measurement and can be mounted directly onto a 35 mm DIN rail or panel. Its compact design allows easy expansion of PLC control systems requiring additional analogue monitoring channels.
