Universal Analog I/O Module Bachmann AIO208

Product Description
The AIO208 is a high-precision, universal analog interface module for the Bachmann M1 automation system. With 8 independently configurable channels, it supports voltage, current, and temperature (RTD) signals, making it ideal for PID loops, process monitoring, and mixed-signal integration. By combining inputs and outputs on a single card, the AIO208 reduces cabinet space and hardware complexity.

Designed for industrial reliability, the module features high-resolution 16-bit A/D and D/A converters, integrated filtering, and 500 V galvanic isolation, ensuring precise signal acquisition and protection from electrical noise. Each channel is fully software-configurable, enabling easy switching between common ranges like 0–10 V or 4–20 mA without hardware modifications.
