Schneider Electric 8030-CRM-310 Fiber Optic Interface Module

Schneider Electric’s Square D SY/MAX Class 8030 Fiber Optic Interface Module, part number 8030-CRM-310, is a dedicated fiber optic communication interface designed for SY/MAX 8030‑class PLC systems. As a member of the CRM family, the 8030-CRM-310 serves as the fiber optic bridge between a SY/MAX processor or network controller and remote I/O or network modules within a Class 8030 rack, enabling data exchange over a fiber optic link. This module is intended to operate within the SY/MAX 8030 ecosystem alongside other CRM-series interface and network modules to form a distributed control network for industrial automation. Typical deployment scenarios include factory floors and distribution centers where fiber connectivity is preferred for noise immunity, longer communication runs, or electrical isolation between devices. The 8030-CRM-310 is one of several CRM‑series options that Schneider Electric/Square D offers to extend SY/MAX control architectures, providing modular interoperability with related CRM modules such as CRM210, CRM211, CRM220, CRM511, and CRM512 for integrated remote I/O and net communications.
