Schneider Electric 990XSM00207 Relay

Schneider Electric 990XSM00207 is a compact relay/IO module from the 990XSM family, designed to extend discrete I/O in industrial automation by integrating with Schneider Electric control architectures and providing a tidy, plug-in expansion path for legacy systems. The module exposes eight input channels and four output channels, all operating at 24 V DC, which supports common industrial sensors and actuators without requiring separate power rails for each channel; this configuration is documented in historical Schneider catalogs and related third‑party listings under the MFR number 990XSM00207. The part is listed as discontinued by Schneider Electric and in distributor catalogs, meaning it is no longer manufactured or sold new through official channels and is typically encountered in existing installations, spare parts inventories, or retirement planning for legacy lines. In catalog references and compatibility charts, 990XSM00207 is described as a Compact module with an eight-input, four-output footprint and 24 V DC operation, a hallmark of Schneider Electric’s X80-era modular I/O approach that emphasized dense, scalable I/O expansion for compact control cabinets.
