Emerson DeltaV KJ3246X1-BA1 S-Series H1 Module with Integrated Power

Hardware Specifications

FOUNDATION Fieldbus H1 and Power Distribution Characteristics

The Emerson DeltaV KJ3246X1-BA1 integrates FOUNDATION Fieldbus H1 communication with field power output functions. Therefore, the module reduces separate power distribution wiring and supports direct connection between DeltaV S-Series I/O infrastructure and H1 field devices.

The module provides field circuit power from 28 to 30 VDC with a rated output of 400 mA per port. Additionally, the local bus interface operates with 12 VDC at 300 mA for DeltaV system communication and module operation.

For process instrumentation networks, the module supports FOUNDATION Fieldbus device communication requirements, including field segment power management and digital communication over twisted-pair wiring. Furthermore, channel-to-channel electrical design supports stable signal transmission in industrial control environments.

Frequently Asked Questions

Field Installation Guidelines

Install the KJ3246X1-BA1 on the designated DeltaV S-Series carrier according to Emerson installation documentation.

Maintain proper separation between field wiring and high-voltage power conductors to reduce electromagnetic interference. Use shielded twisted-pair cable for FOUNDATION Fieldbus H1 connections and terminate cable shields according to site grounding practices.

Verify field power polarity before energizing connected devices. Confirm that field segment loading remains within the specified 28 to 30 VDC output range and 400 mA per port limitation.

Check terminal block key position D6 before installation to prevent incorrect module placement. After installation, verify communication status through DeltaV engineering tools and confirm proper H1 device detection.
