Emerson KJ3002X1-BF1 12P1732X042 VE4003S6B1 Delta V RTD Input Card

   The Emerson KJ3002X1-BF1 DeltaV RTD Input Card is a high-reliability, safety-conscious module designed for precise temperature measurement in process automation systems. Supporting multiple RTD inputs, the module interfaces with DeltaV I/O Termination Assemblies (IOTA) and operates from a common 12–24 Vdc DC-DC supply, ensuring stable performance in industrial environments. For safety, field power must be removed before inserting or withdrawing the unit, while hot-swapping is allowed only under controlled conditions: a single module at a time, total input-power lead inductance below 23 µH, and operation with a certified supply (Ui ≤ 12.6 Vdc, Lo ≤ 23 µH). A rotary keying system guarantees proper module-to-terminal-block alignment, preventing mis-insertion. Field fuses must never be removed while power is applied, even for non-sparking circuits. With its robust design, precise RTD input handling, and built-in safety features, the KJ3002X1-BF1 is ideal for SIL-rated and high-availability applications in chemical, oil & gas, and power generation industries.

   Remove field power-either at the device terminals or by switching off the bussed field-power feed-before inserting or withdrawing the unit.

   The module may be hot-swapped while system power is ON only under these conditions:
– A maximum of one unit is removed or inserted at a time.
– The rack is powered by a KJ1501x1-BC1 dual DC-DC supply running on 12 Vdc or 24 Vdc.
– Total inductance on the input-power leads (including wiring) is below 23 µH, or a certified supply is used whose open-circuit voltage Ui ≤ 12.6 Vdc and Lo ≤ 23 µH.

   A rotary keying system guarantees that, after installation, only a compatible I/O card can mate with its terminal block; set the keys to match the card before locking the assembly.

   Never pull the terminal-block fuse while field power is applied, even for circuits classified as non-sparking.

   The KJ3002X1-BF1 is engineered for ease of integration into DeltaV I/O Termination Assemblies. It offers configurable channel assignments and full compatibility with redundant I/O systems. Field wiring can be safely maintained thanks to clear hot-swap guidelines, and its compact form factor simplifies installation in 19-inch racks. The module's wide operating temperature range and protection against mis-insertion or fuse mishandling enhance reliability and system uptime. Designed for SIL-rated or high-availability applications, the card ensures accurate temperature acquisition and system safety, reducing operational risks in safety-critical industrial processes.

   This RTD input card is commonly used in chemical, petrochemical, and oil and gas industries for real-time monitoring of process temperatures. It integrates seamlessly with DeltaV controllers to ensure precise temperature control for reactors, heat exchangers, and storage tanks. Hot-swap capability allows operators to replace or maintain individual cards without shutting down entire systems, reducing production interruptions. The module's safety features, including rotary keying and fuse protection, ensure compliance with industrial safety standards and help maintain process integrity in high-risk environments where SIL-rated instrumentation is required.
