Product Overview

The GE Fanuc IC693BEM321 is an I/O Link Master for Series 90-30 PLC systems, used to interface the PLC backplane to a serially connected I/O Link network. The module manages data exchange between the PLC CPU and multiple remote/slave link devices, supporting distributed discrete I/O where field wiring must be extended beyond the baseplate.

It installs in a standard Series 90-30 slot and operates from the baseplate 5 VDC supply. Field-side devices on the link use their own power source.

Typical Use Scenarios

The IC693BEM321 is applied when a Series 90-30 system needs remote discrete I/O expansion over a serial link, such as adding I/O in machine subpanels, conveyor zones, or process skids while keeping the main PLC rack centralized. It is also used in retrofit projects to maintain existing I/O Link architectures and minimize rewiring during controller upgrades or cabinet rebuilds.
