IC697CHS771 GE - Dual Redundant Front Mount Rack

GE Fanuc IC697CHS771 Series 90-70 PLC Rack – Dual-System Module Hosting Solution

Model Architecture & Physical Specifications

Model Composition: IC697 (Series Prefix) + CHS (Chassis Type Code) + 771 (Configuration Suffix). Constructed from 1.5mm thick cold-rolled steel for structural rigidity.

• Dimensions: 600mm (L) × 400mm (W) × 150mm (D); net weight: 8kg for stable rack mounting.
• Slot Configuration: 6 standard module slots (50mm spacing) + 1 dedicated power supply slot (leftmost), accommodating 90% of Series 90-70 I/O and communication modules.
• Material Rating: Powder-coated finish with IP20 protection against solid debris ingress.

Electrical Performance & System Support

Engineered for dual-system operation, the IC697CHS771 balances power distribution across two independent setups:

• I/O Bus Requirement: 0.5A current draw from PLC I/O bus for slot activation, ensuring minimal impact on main system power.
• Power Supply Compatibility: - 120/240V AC: 20A (100W) or 11A (55W) operation. - 125V DC: 20A (100W) or 11A (55W) operation. - 24V/48V DC: 18A (90W) operation.
• Cable Limitation: Maximum BTM-to-BRM cable length of 50ft (15.24m) to maintain signal integrity (attenuation ≤3dB at 1MHz).

Installation & Reliability Features

Designed for easy integration and long-term durability:

• Grounding Requirement: Must share ±50mV ground potential with connected racks to prevent voltage spikes.
• Mechanical Stability: Tested to 1G vibration (10-500Hz) and 10G shock (11ms) per IEC 60068-2 standards.
• Mounting Hardware: 4 M4 mounting holes (25mm spacing) for secure attachment to 19-inch industrial racks.
