Emerson KL4502X1-BA1 CHARM Standard Terminal Block

Emerson DeltaV KL4502X1-BA1 CHARM Standard Terminal Block

The Emerson DeltaV KL4502X1-BA1 (part number 12P4990) is a CHARM standard terminal block for use within the DeltaV S-series Electronic Marshalling system.

It provides the physical interface for field wiring and supports installation of CHARM (Characterization Module) components in DeltaV distributed control system architectures.

Functional Characteristics

• Designed for DeltaV Electronic Marshalling systems
• Supports CHARM (Characterization Module) installation
• Provides field wiring termination interface
• Automatic mechanical keying upon first CHARM insertion
• Supports hot-swappable handling conditions as described

Electrical and Environmental Parameters

The terminal block is rated for 250 VAC at 2 A maximum. Operating temperature range is specified from -40 °C to +70 °C. The device carries Zone 2 hazardous area certification (II 3G Ex nA nL IIC Gc or II 3G Ex ec ic IIC Gc) and meets ISA-S71.04-1985 Class G3 environmental classification with IP20 protection.

Installation and System Integration

• Mounts onto CHARM Baseplates such as KL4201X1-BA1
• Baseplate supports up to 12 modules per assembly
• Mechanical keying prevents incompatible CHARM insertion after initial set
• Hot-swapping permitted under stated voltage limitations (Voc ≤ 26.4 VDC)
