The RTU3220 is a compact, power-efficient Remote Terminal Unit/Intelligent End Device (RTU/IED) designed for the electric industry. RTU3220s monitor both AC and DC analog inputs as well as discrete digital inputs, while calculating comprehensive power-quality values and waveforms.


The RTU3220’s single PC-board construction features a System-on-Chip integrated circuit that decreases board complexity and reduces the number of exposed interconnections. All computing components and high-speed bus are contained within a sealed housing. The unhoused portion of the PC board is conformal-coated to protect RTU components from harsh environments.

In addition to reporting eight digital statuses and eight analog values, the RTU will calculate RMS voltage, RMS current, watts, VAR, phase angle, THD, and power factor. The RTU3220 will create and transfer COMTRADE files given user defined parameters.

The RTU3220 features:

  • A powerful, yet low power consumption processor
  • 9-30VDC power supply
  • DNP 3.0, Modbus, and PG&E protocol support
  • 10/100 Base-T Ethernet port with RJ-45 connector
  • Two RS-232 ports
  • One RS-485 connection
  • State logic programming
