Product Description

Overview

The KJ4110X1-BB1 from Emerson is a Series 2 Redundant Wireless I/O Gateway for DeltaV™ Distributed Control Systems. It enables seamless integration of WirelessHART® field instruments into the DeltaV network, bridging wireless sensors such as pressure, temperature, and vibration devices directly into process control loops. The module is engineered for high availability, typically deployed in redundant pairs to maintain uninterrupted wireless communication even during hardware failure.

Core Features

Reliable WirelessHART Connectivity

• Supports self-organizing WirelessHART mesh networks for >99% data reliability

• Transparent access to all HART variables, device diagnostics, and alerts

High Availability & Redundancy

• Redundant operation ensures continuous network management if one gateway fails

• Hot-swappable modules allow replacement without disrupting wireless data flow

DeltaV System Integration

• Auto-recognition reduces commissioning time

• Secure wireless communication with AES-128 encryption and authentication

Rugged Industrial Construction

• Conformal coating (G3) safeguards against moisture, chemical exposure, and corrosion

• Operating temperature range from -40°C to 70°C for field or cabinet installation
