Tired of unreliable sensor signals that interrupt your automation line? The ASCON TECNOLOGIC AI-02UI gives you a sturdy, remote analog input solution that captures temperature, pressure, current or voltage with high precision. It fits into a CANopen network and sends clean data to your controller, so you never have to guess why a process stopped. If you need accurate, isolated measurements without wiring chaos, this module is the answer.
ASCON TECNOLOGIC AI-02UI, 24 Vdc 16 bit 2-channel Remote Analog Input module
Many small to medium factories struggle with noisy analog signals that cause false alarms and costly downtime. The lack of electrical isolation makes the whole system vulnerable to voltage spikes, and the limited resolution of cheap modules hides small but important changes. The AI-02UI removes these worries by offering 16-bit resolution, 0.1 % full-scale accuracy, and 2.5 kV isolation on each channel. It talks over CANopen, so you can place it near the sensor and keep long cables short, reducing interference and maintenance effort.
