The Phoenix Contact Axioline F I/O module designed for the Axioline F modular I/O system, primarily used for acquiring digital signals. It serves as a modular I/O device, attachable to the Axioline F local bus, facilitating communication of I/O data to the Axioline F controller or bus coupler, which acts as the station's head. As an intrinsic safety I/O module, it allows direct connection of intrinsically safe field I/O to its terminals. Specifically, the digital input module with NAMUR capabilities is adept at collecting digital input signals and supporting NAMUR proximity and close contact switches. It subsequently makes this acquired information available to the controller/bus coupler through the Axioline F local bus, thereby enhancing the system's overall functionality and safety.
