Schneider Electric AS-BDEP-218 Discrete Input Module

Schneider Electric AS-BDEP-218 is a 16-channel discrete input module for Modicon Compact PLCs that accepts 115 VAC field signals. It provides 1.8 kV isolation between field wiring and the logic, protecting the controller from voltage transients on sensors and switches. This isolated 16-point input block is designed to expand digital input capability for automation systems, often wired to devices such as pushbuttons, limit switches, or proximity sensors that operate at 115 VAC. Used as an I/O expansion module in Schneider Electric's Modicon Compact family, the AS-BDEP-218 (also referenced as DEP218) integrates with compatible Modicon controllers to read and relay the status of each input channel to the PLC. In practice, it simplifies wiring by consolidating multiple 115 VAC inputs on a single device, enabling scalable automation and straightforward sensor integration. The model is commonly listed as AS-BDEP-218, DEP218, or 16PT INPUT MOD, and is recognized as an isolated 16-point input module within the Schneider Electric ecosystem.
