Replacement & Compatibility FAQ
Q: Can I replace 1426-M5E-DNT with 1426-M5E-ENT without rewiring?
A: The physical mounting and CT wiring are identical. However, you will need to replace the DeviceNet drop cable with an Ethernet cable and reconfigure the network scanner. Consult your system integrator before switching protocols.
Q: Is the 1426-M5E-DNT still in production?
A: Rockwell Automation has transitioned focus to EtherNet/IP variants. The DNT model may be available as new-old-stock (NOS) or refurbished. Konmask maintains verified inventory — contact us for current availability.
Q: What CTs are compatible with this unit?
A: Any standard 5A secondary CT rated for your line voltage. Accuracy class 0.5 or better is recommended for billing-grade metering.
Q: Can this unit measure three-phase unbalanced loads?
A: Yes. The 1426-M5E-DNT supports 3-phase 3-wire and 3-phase 4-wire configurations and reports per-phase voltage and current independently.
Q: Do you provide a certificate of conformance (CoC)?
A: Yes, CoC and supply chain documentation are available upon request for all orders.
