Description
Product Description
The GE Fanuc IC693BEM330 is a Bus Expansion Module (BEM) engineered for the Series 90‑30 PLC family, enabling seamless extension of CPU base racks to additional expansion racks. This module supports scalable I/O configurations, allowing larger and distributed control systems without replacing the central CPU.
Designed for high-speed serial communication, the IC693BEM330 ensures reliable data transfer between the CPU and connected expansion racks. LED indicators provide instant visual feedback for communication status and module health, simplifying diagnostics and maintenance. With support for up to seven expansion racks and a maximum cable length of 50 ft (15 m), it is ideal for mid-sized distributed automation systems.
