Description
Product Description
The IC697BEM742 is a precision bus expansion module for the GE Fanuc Series 90-70 PLC family, designed to extend the backplane and support additional PLC racks. By enabling communication between the main CPU and expansion racks, this module allows larger and more complex automation systems to be implemented without compromising signal integrity.
Equipped with dual FIP bus connectors and a serial interface, the IC697BEM742 ensures high-speed, reliable data transfer while providing electrical isolation to minimize noise and interference. The module operates at 5 VDC, consumes 1.3 A on the backplane, and features six LED indicators for status monitoring. Its single-slot design and standard Series 90-70 dimensions make installation simple and space-efficient.
Ideal for process control, large-scale industrial automation, and distributed I/O systems, this module is typically available new or refurbished with standard supplier warranties.
