Allen-Bradley 1408-EM3A-ENT Power Monitor 1000 – PowerMonitor 1000 Series Ethernet Energy Metering Module
When a facility loses real-time visibility into its electrical consumption, the consequences cascade quickly: undetected power quality issues trigger unexpected equipment shutdowns, energy waste goes unaccounted, and maintenance teams are left chasing faults without data. In energy-intensive industries — manufacturing, water treatment, mining, and data centers — the absence of a reliable power monitoring node is not merely an inconvenience; it is a direct threat to uptime, compliance, and operational cost control.
The Allen-Bradley 1408-EM3A-ENT is a mid-range energy metering module within Rockwell Automation’s PowerMonitor 1000 series, designed to deliver accurate, real-time electrical measurement with native Ethernet/IP connectivity. Positioned as a cost-effective yet capable solution, it bridges the gap between basic panel meters and full-featured power quality analyzers, making it a widely deployed choice in global industrial automation projects where EtherNet/IP integration with ControlLogix, CompactLogix, or FactoryTalk systems is required.

Frequently Asked Questions
Q: Is the 1408-EM3A-ENT still in production by Rockwell Automation?
A: The PowerMonitor 1000 series has reached end-of-life status with Rockwell Automation. However, Konmask.com maintains stock of verified surplus units. Contact us for current availability.
Q: What is the difference between 1408-EM3A-ENT and 1408-EM3A?
A: The “-ENT” suffix denotes the EtherNet/IP communication variant. The base 1408-EM3A model uses RS-485 (Modbus RTU / DF1) communication. The ENT version is required for direct integration into EtherNet/IP-based control networks.
Q: Can this module be used with non-Rockwell PLCs?
A: While the 1408-EM3A-ENT uses EtherNet/IP, interoperability with non-Rockwell controllers depends on the third-party PLC’s EtherNet/IP scanner capability. Consult your PLC vendor’s documentation or contact us for guidance.
Q: Do you provide a warranty on surplus Allen-Bradley modules?
A: Yes. Konmask.com provides a limited warranty covering DOA (Dead on Arrival) units. Warranty terms are specified in our quotation. Extended warranty options may be available — please inquire.
Q: Can you assist with export documentation for international orders?
A: Yes. We provide commercial invoices, packing lists, and can assist with certificate of origin and other export compliance documents required for customs clearance in your country.
