I/O Interface Module GE Fanuc - IC697BEM761

Complete Model: IC697BEM761

Main Features:

• Current: 1.3 A
• Connectors: Two 37-pin ports for upstream and downstream chaining
• Rack Support: Up to 8 maximum
• I/O Capacity per Rack: 256 points
• Indicators: 3 LEDs (RACK, MODULE, I/O CHAIN)
• Data Handling: Interfaces via I/O bus with IC600 CPU

Indicator Functions:
The front panel provides three diagnostic LEDs:

RACK: Active when a rack-level fault is detected

MODULE: Indicates internal errors in the I/O interface module

I/O CHAIN: Alerts on downstream chain or I/O communication fault

Detailed Configuration by Model Suffix:
IC697: Signifies compatibility with the Series 90-70 system chassis
BEM: Indicates it is a Bus Expansion Module
761: Specific version with enhanced diagnostic features and multi-rack support

Advanced Technical Details:

• The module supports a reserved I/O address range to ensure non-conflicting communication with the IC600 CPU.
• Termination resistors are built-in for signal integrity across racks.
• Each connected rack can be configured for either 128 or 256 references, depending on system requirements.
• Maximum system scalability: 8 racks × 256 points = 2048 I/O per direction.
