Description

The Honeywell 51202971-101 is a Series 8 I/O Link 1 (IOL1) Drop Cable Assembly designed for interconnecting Series 8 Input/Output Termination Assemblies (IOTAs) within Experion LX control system cabinets. Operating as Cable B in a redundant I/O Link configuration, this 51202971-101 multi-drop cable features a gray jacket with green connector labels marked for IOL1B identification. It provides vertical signal and communications distribution across mounting plate columns at a 750 Kbps transfer rate, connecting C300 controllers and Series 8 I/O modules to system header boards and adjacent IOTAs.

Features

Redundant Link B Identification: Features a green connector label and IOL1B symbol marking for accurate identification in I/O Link 1 redundant pairs.
Multi-Drop Vertical Routing: Engineered with 6 drops at a 6-inch (152 mm) pitch to route vertically within cabinet mounting plates.
High-Speed Communication: Supports the standard 750 Kbps Series 8 I/O Link serial communication network.
System Integration: Connects C300 controllers, header boards, and various Series 8 IOTAs without exiting the physical enclosure complex.

Applications

Honeywell Experion LX Series 8 Control System Cabinets
C300 Controller to Series 8 I/O Link 1 (IOL1) interconnection
Vertical IOTA signal distribution across cabinet mounting plates

Installation Guidelines

Enclosure Boundary: Keep I/O Link cables entirely within the physical confines of the cabinet or cabinet complex; cables must not exit the front, rear, sides, top, or bottom.
Channel Placement: Route cable vertically along designated wireways in cabinet mounting plates to connect Series 8 IOTAs.
Voltage Separation: Ensure IOTAs associated with field wiring over 30 V are physically separated from IOTAs associated with field wiring under 30 V to minimize electrical interference.
Pair Matching: Install alongside the corresponding Cable A assembly (51202971-100) to form a complete redundant I/O Link 1 connection.
