Application-Specific FAQ
Q: Is the KJ3003X1-EA1 compatible with both S-Series and M-Series DeltaV controllers?
A: Yes. This power supply module is designed for the DeltaV I/O subsystem bus and is compatible across DeltaV M-Series and S-Series controller generations. Always verify your specific backplane revision with Emerson’s compatibility guide.
Q: Can I run two KJ3003X1-EA1 modules in a redundant configuration?
A: Yes. DeltaV supports N+1 power redundancy. Two units installed in the same carrier will load-share and provide automatic failover if one module fails.
Q: What is the difference between KJ3003X1-EA1 and 12P0921X032?
A: These are the same physical module. KJ3003X1-EA1 is the Emerson catalog part number; 12P0921X032 is the Emerson internal reference/revision number printed on the module label. Both identifiers refer to the identical hardware.
Q: Is this a new or refurbished unit?
A: Units are sourced as tested surplus/refurbished unless explicitly listed as new. All units pass our functional test protocol. Condition is clearly stated on the product listing and confirmed in the order confirmation.
Q: Do you provide a warranty?
A: Yes. Konmask offers a 90-day functional warranty on all tested modules. Extended warranty options are available — contact us for details.
Q: Can this module be used in a SIL-rated safety loop?
A: The KJ3003X1-EA1 is a standard DeltaV power module. For SIL-rated applications, consult Emerson’s functional safety documentation and your SIS engineer to confirm suitability within your safety instrumented system architecture.
