Schneider Electric BMXSDO0802 | Modicon X80 Relay Output Module

Product Description

The Schneider Electric BMXSDO0802 is a discrete relay output module within the Modicon X80 I/O platform. It is designed for seamless operation with Modicon M340 and M580 PLC systems.

This module provides eight mechanical relay outputs capable of switching both AC and DC loads reliably. Therefore, it suits automation systems that require electrical isolation and flexible voltage handling.

Relay output technology allows direct control of field devices without additional interface relays. Moreover, this design improves system simplicity while maintaining strong electrical separation between logic and load circuits.

The BMXSDO0802 integrates directly into the X80 backplane, supporting consistent diagnostics and predictable system behavior. In addition, its long mechanical service life supports continuous industrial operation.
