The Bachmann DIO248 (00019116-00) is a high-density, multifunctional digital I/O module designed for the Bachmann M1 controller system. Its core function is to control digital field devices—such as contactors, relays, pneumatic and hydraulic valves—while simultaneously reading signals from digital sensors, detectors, or switches. It also integrates high-speed counter and interrupt functions, making it suitable for complex industrial applications requiring fast response and position detection.
