The PM5330 (PowerLogic PM5000 series) and the PM2130 (EasyLogic PM2000 series) are two panel-mounted power meters from Schneider Electric. Both have a 96 mm wide front, both have an RS485 Modbus RTU port, and both measure active energy to class 0.5S (IEC 62053-22) and show harmonic distortion up to the 31st harmonic. The PM5330 adds digital inputs and relay outputs and a backlit LCD, so it also serves for alarms and control signals. The PM2130 has a simple LED display and no digital inputs or outputs.

Which one
- Choose the PM2130 when you only need to read voltage, current, power, energy and harmonics locally, or to send them over RS485.
- Choose the PM5330 when you also need digital inputs, relay outputs for alarms or control, and a larger display with menus.
The PM2130 and the PM5330 differ in measuring range, so check them against your panel before ordering.
