Product Information

Product Description

NETIO PowerPDU 4C is a small 110/230V PDU (Power Distribution Unit). Each of the four IEC-320 C13 outlets can be independently controlled (On / Off / Reset / Toggle). Electrical parameters (A, W, kWh, TPF, V, Hz) are measured with high accuracy at each outlet.

This smart power distribution unit features two LAN ports (and a built-in Ethernet switch) for connecting to a LAN. Each power output supports ZCS (Zero Current Switching) to protect the connected equipment.

With the NETIO Cloud service, the outputs can be controlled from anywhere. The NETIO Cloud service is provided for a fee; it uses SSL security.

Outputs can be controlled in the device web administration by using a mobile app or over various M2M API protocols including REST API, SNMP, MQTT, Modbus/TCP and others.

Custom Lua scripts can run directly in the NETIO PowerPDU 4C. As a special feature, NETIO PowerPDU 4C provides a RS-232 serial port (green 3-pin terminal block) that can be controlled with a Lua script or used as a TCP tunnel (remote serial port).

NETIO PowerPDU 4C is unique as it supports many network protocols that can be used to control each power outlet individually and measure electricity consumption.

Thanks to many supported M2M APIs, NETIO devices are easy to integrate into existing systems that consist of HW/SW from many different producers.

This smart pdu measures electrical parameters separately for each output. Measured values are displayed in the web administration interface and accessible via M2M protocols. Measurement accuracy is better than 1%.


This product can be connected to the NETIO Cloud service (100 outputs can be controlled from 1 web screen). NETIO Cloud is an ideal solution for remote control and restarting. 

RS-232 serial port of NETIO 4C

NETIO PowerPDU 4C provides a RS-232 serial port at its 3-pin green terminal block. The serial port can be used as a remote serial port (tunnel from a TCP connection to the serial port), or controlled with Lua scripts.

Lua scripts can send strings to this serial port and read any responses. This makes it easy to connect various industrial devices in order to, for example, react to a high temperature sensed by a RS-232 sensor by switching on a particular outlet.

Lua – Programmable scripts

PowerPDU 4C can run custom scripts written in the Lua language. The user enters the script in the device’s web administration interface. There is no need to install any additional software. The scripts run directly in the device and do not require any cloud connection.

Built-in Ethernet switch

NETIO PowerPDU 4C includes two RJ45 ports for connecting to a LAN. The device includes a built-in unmanaged)Ethernet switch. Several PowerPDU 4C units can be “daisy-chain” connected to a single RJ45 LAN socket; each PowerPDU 4C will have its own IP address.

ZCS (Zero Current Switching)

An important feature of NETIO PowerPDU 4C is ZCS (Zero Current Switching). ZCS means that the control relay switches the IEC-320 C13 output power outlet on or off when the current crosses the zero level.

Mobile application

  • The mobile app (for Android) can be used to control several devices and all their outputs.
  • The mobile device must be connected to the same LAN (via WiFi).
  • NETIO Mobile2 can scan the LAN and discover connected devices. WiFi connection to the LAN is required.


  • Built-in Ethenet switch
  • No momentary output switching even during FW updgrade
  • Scheduler function with a graphical interface
  • IP WatchDog function
  • Support for measurements with external sensors
  • M2M APIs supported including SNMP v1 & MQTT-flex
  • LUA scripting language runs directly in the device
  • Support for reading from / writing values to UPC using SNMP
