Product Overview

The Emerson KJ3206X1-BK1 (Part Number 12P4696X032) is a high-density S-Series Discrete Output Module engineered for the DeltaV™ Distributed Control System. This 32-channel card provides 24 VDC High-Side switching, allowing the system to command a large array of field devices from a single I/O slot. By switching the positive side of the 24 VDC field circuit, it provides a standardized interface for driving solenoids, small motor starters, and indicating lamps.

Designed for high-performance automation, the KJ3206X1-BK1 balances high-density I/O with rugged environmental protection. It is specifically built to integrate with the DeltaV S-Series hardware platform, utilizing specialized terminal block keying to ensure correct installation. This module is an ideal solution for plants requiring extensive discrete control within a compact cabinet footprint, offering the reliability needed for continuous process industries.

Technical Characteristics and Environmental Resilience

This module is constructed to maintain operational integrity under the mechanical and chemical stresses common in industrial facilities.

• High-Density Control: 32 independent channels provide significant space savings on the I/O carrier while maintaining individual channel isolation.

• High-Side Switching: Optimized for 24 VDC sourcing, where the card supplies power to the field load, facilitating easier ground-fault detection in control loops.

• Extreme Thermal Tolerance: Validated for operation in ambient temperatures from -40°C to +70°C, making it suitable for remote instrument enclosures.

• G3 Corrosive Protection: Fully compliant with ISA-S71.04-1985 Class G3 standards, providing resistance against harsh airborne contaminants and sulfurous gases.

• Shock and Vibration Resistance: Built to withstand 10g mechanical shock and vibrations up to 150 Hz, ensuring stability when mounted near heavy processing machinery.

• Advanced Power Management: Operates on 12 VDC local bus power with a bussed field power capacity of 3.2 A per card to handle simultaneous channel activation.
