Overview Manuals Applications Safety Environment Installation

Features:

  • Terminates three-wire discrete-input field circuits on the dedicated CHARM baseplate interface.
  • Supplies a fused injected-power path rated for circuits up to 30 VDC at 1 A.
  • Uses automatic keying to prevent insertion of an incompatible CHARM type at the terminal position.
KL4502X1-PA1 is the DeltaV 3-Wire DI Fused Injected Power Terminal Block within the DeltaV CHARM I/O family.

Three-wire discrete-input loops that require a fused injected-power terminal arrangement.

KL4502X1-PA1 is a fused injected-power terminal block for three-wire DI circuits. Its hazardous-area handling restrictions apply to both the terminal and connected CHARM.

  • Three-wire discrete-input loops that require a fused injected-power terminal arrangement.
  • DeltaV CHARM cabinets engineered for the model's Class I Division 2 or Zone 2 approvals.
  • Terminal-block replacement where automatic keying and the PA1 circuit identity must be preserved.
  • Apply the II 3G Ex ec IIC Gc approval only under the listed installation conditions.
  • Do not remove the terminal from energized field wiring unless the location is known to be nonhazardous.
  • Use the specified DeltaV Zone 2 installation instructions with this hardware.
  • Supports operation across the specified -40 to +70°C ambient temperature range.
  • Handles relative humidity from 5 to 95 percent when condensation is prevented around the installed terminal assembly.
  • Meets ISA Class G3 contaminant exposure requirements together with the stated shock and vibration limits.
  • Match three-wire DI field wiring to the fused injected-power circuit.
  • Confirm PA1 keying before inserting the associated CHARM.
  • Keep field power within the 30 VDC and 1 A maximum rating.
Description
KL4502X1-PA1 is an Emerson DeltaV CHARM terminal block for three-wire discrete-input circuits that use fused injected power. The official instruction sheet specifies a maximum rating of 30 VDC at 1 A.

The terminal block operates from -40 to +70°C and is documented for Class I, Division 2 and Zone 2 installations under the stated approval conditions. Automatic mechanical keying helps preserve the intended CHARM-to-terminal pairing.

De-energize or follow the documented nonhazardous-location conditions before handling energized field wiring. Verify the PA1 suffix, injected-power design, field circuit, and area classification before installation.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Which circuit type is KL4502X1-PA1 designed for?
It is a fused injected-power terminal block for three-wire discrete-input wiring.
What maximum electrical rating applies to PA1?
The official instruction sheet states 30 VDC at 1 A maximum.
How is the compatible CHARM position protected?
Automatic mechanical keying sets the terminal position for the installed CHARM type.
Can energized field wiring be removed in a hazardous area?
Only under the exact handling conditions stated by Emerson; otherwise the circuit must be de-energized.
Which atmospheric environments are documented?
The unit is rated for ISA-S71.04 Class G3 airborne-contaminant conditions.
