Product Overview

The 1420-V1A-485 is an Allen-Bradley PowerMonitor 500 serial power meter module. It belongs to the Bulletin 1420 PowerMonitor 500 family, providing local LCD display, analog output, and Modbus RTU (RS-485) communication. It measures fundamental electrical parameters including voltage, current, power, energy, power factor, frequency, and demand for panel-mounted energy monitoring. Typical industrial use includes sub-metering on distribution panels, branch circuit monitoring, and energy analytics integration. The 1420-V1A-485 supports integration into Modbus-based supervisory systems.
