Schneider Electric AS-BDEP-218 PLC Input Module

Schneider Electric's AS-BDEP-218 (also cataloged as DEP 218 for the AEG Modicon line) is a 16-channel discrete input module designed to expand a Modicon PLC's digital input capability. It provides sixteen input points for monitoring field devices such as switches or sensors and interfaces with the controller via the PLC backplane. Each channel supports 115 VAC discrete input signaling, making it suitable for standard line‑voltage signaling used in industrial automation. As an I/O expansion module, it plugs into a compatible Modicon rack to extend the controller's input count without external multiplexing. Typical applications include machine control, panel automation, and process monitoring where multiple contact closures must be read in real time. The AS-BDEP-218 is part of Schneider Electric's Modicon discrete input family and is designed to integrate with Schneider/Modicon backplanes for straightforward, scalable input expansion within centralized control systems.
