KJ2231X1-EA1 | Emerson DeltaV SIS Relay Output Module

Product Overview

The Emerson KL3002X1-BA1 is a Discrete Output (DO) High-Side CHARM module for the DeltaV™ Electronic Marshalling system. It delivers 24 VDC high-side switching for discrete output control, enabling flexible, hot-swappable I/O configuration without traditional marshalling rewiring. Ideal for oil & gas, petrochemical, and power generation applications.

Installation Guide

1. Confirm the CHARM base/carrier power is off before insertion in hazardous areas.
2. Align the CHARM with the carrier slot and press firmly until seated.
3. Verify the terminal block key is set to position 3C for proper mating.
4. Connect field wiring to the terminal block according to the wiring diagram.
5. Use DeltaV Explorer to auto-detect and configure the new CHARM in the control strategy.

FAQ

• Q: What is a CHARM and how does it work?
  A: A CHARM (Characterization Module) is a hot-swappable signal conditioning module that plugs into a CHARM I/O Card (CIOC), allowing signal type to be defined by the CHARM rather than fixed wiring.
• Q: Can KL3002X1-BA1 be hot-swapped?
  A: Yes, in non-hazardous areas. In hazardous areas, power must be removed before insertion/removal.
• Q: What is the load current capability?
  A: The field circuit draws 5 mA per channel; refer to system documentation for total load limits.
• Q: Is this module compatible with all DeltaV systems?
  A: It is designed for DeltaV S-Series with Electronic Marshalling (CHARMs I/O subsystem).

Selection Tips

• Use high-side CHARMs when sinking current from the load is preferred for safety or compatibility.
• Verify carrier compatibility (CIOC) before ordering; each CIOC supports multiple CHARM slots.
• For hazardous area installations, ensure proper Ex ec IIC Gc compliance and follow Zone 2 guidelines.
