Product Overview
The 1408-EM3A-485 is an Allen-Bradley PowerMonitor 1000 series energy, demand, and power monitoring module. It functions as a meter that integrates into industrial control systems, measuring electrical parameters-such as voltage, current, real/reactive/apparent power, energy (kWh, kVARh, kVAh), demand values (actual and projected), power factor, frequency, and unbalance. It supports serial communications over RS-485. Typical industrial applications include control panels, distribution centers, and motor control centers where detailed energy monitoring and demand tracking are required.
