Product Overview
The Allen-Bradley 1408-EM3A-ENT is an Energy, Demand, and Power monitoring member of the PowerMonitor 1000 platform. It provides voltage, current, frequency, real/reactive/apparent power, energy, demand, and power factor measurements. It supports both RS-485 (DF1, Modbus RTU) and Ethernet/IP communications via an integrated RJ-45 port, and can be configured through its embedded web interface. Typical industrial uses include energy management, load profiling, and power monitoring in control panels in manufacturing, utilities, and infrastructure systems.
