Description
Product Overview
The GE Fanuc IC697CHS770E is a dual redundant rear mount rack chassis for the GE Series 90-70 PLC platform. The suffix “E” denotes the hardware revision of the IC697CHS770 base rack. This chassis is split into two independent 6-slot sub-systems plus dedicated power supply slots, enabling installation of two separate or redundant PLC control systems within a single rack housing. The integrated high-speed VME backplane supports all Series 90-70 CPU, discrete I/O, analog I/O, communication and specialty modules, as well as compatible IC687 VME modules. Designed for high-availability control applications such as power generation, oil & gas, and heavy industrial processes, this legacy rack is end-of-active production and widely stocked as critical maintenance spare for existing 90-70 installations.

Storage & Installation Guidelines
Storage Requirements
- Store in dry temperature-controlled warehouse; recommended ambient 10°C ~30°C, RH <70% non-condensing
- Remain sealed inside original packaging before installation
- Protect from mechanical shock, continuous vibration, dust and corrosive vapors
- ESD wristband required when unpacking and handling backplane and modules
Installation Instructions
- Execute lock-out/tag-out and fully de-energize all rack power before rack or module replacement
- Wear ESD protective gear to prevent electrostatic damage to backplane and electronic modules
- Mount the IC697CHS770E chassis inside the control cabinet using mounting hardware
- Install power supply modules into the dedicated left-hand slots of each sub-system
- Insert CPU, I/O and communication modules into the 6-slot sections, aligning connectors with the VME backplane
- Wire rack AC/DC input power, field I/O cables and communication wiring per GE Series 90-70 drawings
- Restore power, verify backplane power and module LED status
- Download PLC logic, perform I/O checkout and redundant system failover test; commissioning must be completed by certified GE Fanuc PLC technicians
FAQ
Q: What system uses IC697CHS770E? A: It is a dual redundant rear mount rack chassis for GE Fanuc Series 90-70 large-scale PLC control systems.
Q: What does the suffix E mean? A: “E” indicates the hardware revision level of the IC697CHS770 rack chassis; revision matching is recommended for spare replacement.
