The Festo CPX-E-16DI is a 16-channel digital input module in the CPX series, designed as a PLC expansion module for distributed automation systems. It snaps onto the CPX-E backplane, extending the I/O count of a CPX-E controller or bus node.
Integration note
The module mounts on the CPX-E system rail alongside other CPX-E I/O and bus-node modules. No special wiring beyond the standard CPX-E backplane connection is needed; the 16 digital inputs are accessed via the module's front-panel M12 or push-in connectors (per the system's wiring scheme).
