Description

Product Description – Vertical I/O Carrier

Overview

The KJ2201X1-HA1 from Emerson is a 4-wide vertical I/O carrier designed for the DeltaV™ Distributed Control System. It provides the backbone for vertical I/O installations, enabling modular integration of four S-Series I/O modules within space-constrained or specialized cabinet environments. The carrier distributes both LocalBus communication signals and field power, creating a compact and organized wiring architecture.

Key Features

Space-Saving Vertical Design

• Optimized for cabinets or racks where horizontal space is limited

• Supports high-density mounting of four I/O modules in a compact footprint

Reliable Power and Data Distribution

• LocalBus extension to all slots for low-latency communication

• Field power distribution up to 12 A simplifies wiring requirements

Maintenance-Friendly

• Supports hot-swappable I/O modules for uninterrupted operation

• Integrated shield grounding reduces electromagnetic interference and preserves signal quality

Rugged Industrial Durability

• G3 conformal coating protects against moisture, corrosion, and airborne contaminants

• Operates reliably in cabinet temperatures from -40°C to 70°C

• Certified for hazardous areas: ATEX/IECEx Class 1, Div 2 / Zone 2
