IC693CBL301 | GE Fanuc | Wye (Y) Expansion Cable

Product Summary

The IC693CBL301 is a Wye (Y) expansion cable used for interconnecting baseplates in Series 90-30 PLC expansion or remote I/O configurations. It serves as a jumper cable for daisy-chaining multiple baseplates in multi-rack systems.

Core Specifications

• Model Number: IC693CBL301
• Cable Type: Wye (Y) Expansion Cable
• Length: 2 m (6.56 ft)
• Connectors: 25-pin D-subminiature male on one end, 25-pin D-subminiature female on the other (with Wye configuration for branching)
• Cable Construction: Shielded, twisted-pair cable (Belden 8107 or equivalent recommended)
• Application: Interconnection of expansion and remote baseplates

Electrical & Interface Characteristics

• Function: Provides parallel I/O bus expansion between baseplates
• Maximum System Configuration: Supports up to 8 baseplates (local + expansion/remote) depending on total cable length and power considerations
• Termination: Proper termination required at the end of the expansion bus (see IC693ACC307 Bus Terminator)

Installation Guide

1. Power off the PLC system before connecting or disconnecting expansion cables.
2. Connect the male end of the cable to the expansion port on the CPU baseplate or previous expansion baseplate.
3. Connect the female end to the next baseplate in the chain.
4. For Wye configurations, use the branching legs to connect multiple baseplates as required.
5. Ensure total cable length does not exceed system limits and install a bus terminator at the final baseplate.
6. Verify proper grounding and shielding to minimize noise.

Selection Guidelines

• Use IC693CBL301 for medium-distance baseplate interconnections (2 m).
• For shorter distances, select IC693CBL300 (1 m).
• For longer distances with built-in termination, select IC693CBL302 (15 m).
• Always calculate total expansion cable length and power budget when designing multi-rack systems.
