IC697CHS771 GE Fanuc 6-Slot I/O Expansion Chassis

Product Overview

The GE Fanuc IC697CHS771 is a specialized 6-slot chassis for the Series 90-70 PLC system, serving as a reliable dual-system module hosting solution. Engineered for structural rigidity, it is constructed from 1.5mm thick cold-rolled steel and finished with a durable powder coating. This rack provides six standard module slots with 50mm spacing, along with a dedicated power supply slot on the leftmost side, making it compatible with approximately 90% of all Series 90-70 I/O and communication modules.

Electrical Performance & Compatibility

The IC697CHS771 is designed to minimize its electrical footprint, drawing only 0.5A from the PLC I/O bus for slot activation. This efficiency allows for a balanced power distribution across independent system setups. The rack is highly versatile, supporting multiple power supply configurations including 120/240V AC (up to 20A/100W), 125V DC, and 24V/48V DC. To ensure signal integrity, the maximum cable length between BTM and BRM modules is limited to 50 feet (15.24m), maintaining low attenuation for critical data paths.

Physical Characteristics & Weight

The physical build of the IC697CHS771 is tailored for industrial environments where stability is paramount. The unit weighs 8 kg (approx. 17.6 lbs), providing a solid foundation for rack-mounted electronics. With dimensions of 600mm (L) × 400mm (W) × 150mm (D), it fits efficiently into standard 19-inch industrial enclosures. The chassis carries an IP20 protection rating, shielding internal components from solid debris and accidental contact during operation and maintenance.

Technical Specifications

Reliability and Installation

Installation of the IC697CHS771 is straightforward, utilizing 4 M4 mounting holes for secure attachment to panel or rack surfaces. For maximum reliability, the system must share a ±50mV ground potential with all connected racks to mitigate the risk of voltage spikes. It has been rigorously tested to IEC 60068-2 standards, ensuring it can handle 1G of vibration and 10G of shock. These features make it a dependable choice for high-availability industries like wastewater treatment, steel manufacturing, and power distribution.

Technical FAQs

Q1: What is the maximum cable length for rack expansion?
A1: To maintain signal integrity and ensure an attenuation level of ≤3dB at 1MHz, the maximum length for BTM-to-BRM cables is 50 feet (15.24m).

Q2: Can I install any Series 90-70 module in this rack?
A2: The rack accommodates roughly 90% of the series' I/O and communication modules. Always check the specific slot width of the module; these slots use 50mm spacing.

Q3: Is the power supply slot interchangeable with I/O modules?
A3: No, the leftmost slot is dedicated specifically to the power supply module and cannot be used for standard I/O or CPU modules.
