NETIO PowerPDU 8QS is a PDU (Power Distribution Unit) with eight power outputs (8x IEC-320 C13) controlled and metered over a LAN. It fits into a 19” cabinet (1U). Each output can be switched on/off individually. PowerPDU 8QS supports two channels for electrical measurements: the PDU as a whole (all outputs combined), and the first output separately (All Outputs + 1). A digital input (DI) can be used to control the outputs or count S0 pulses (electricity meter output).

NETIO PowerPDU 8QS can be configured with a web browser (allows output control, connection to NETIO Cloud, Open API communication settings, etc.).

Thanks to the Open API, integration with third-party systems using various protocols (JSON, Modbus/TCP, SNMP, MQTT-flex, Telnet, ...) is easy. Ready-made AV drivers make it simple to connect the NETIO PDU to professional Audio/Video systems such as Neets, Crestron, Control4, RTI, Savant and more.

With the NETIO Cloud service, the outputs can be controlled from anywhere. The NETIO Cloud service, provided for a fee, uses SSL security and servers in Europe.

The NETIO Mobile2 app controls each output individually over LAN (local network).

To switch the outputs on in a sequence, a power-up delay can be configured for each output.


Open API: Supported M2M protocols

One Open API protocol can be used at a time, chosen from among the supported M2M protocols:

  • SNMP v1                               AN11, AN41
  • SNMP v3
  • MQTT-flex                             AN40
  • Telnet                                     AN10
  • Modbus/TCP                         AN27AN22, AN37
  • JSON over HTTP                 AN21AN30AN42
  • XML over HTTP                    AN20AN31
  • URL API (http get)                AN19AN29
  • HTTP(s) Push JSON                      
  • HTTP(s) Push XML           

Regardless of the Open API used, the PowerPDU 8QS can be always controlled from its web interface and from the NETIO Cloud service. The customer can take advantage of the NETIO Cloud service and one Open API protocol simultaneously.

Industrial product quality

 NETIO PDUs are made with quality in mind. Each unit includes a set of supporting functions to ensure reliability and long service life of the product in real-life conditions.
  • Open M2M API
  • Wide operating temperature range
  • PowerUp state – defined output state after power-up
  • PowerUp delay – outputs switched on after a delay
  • Input current up to 16A (output current max 10A / output)
  • Low internal consumption
  • Firmware upgradeable over the web, backwards compatibility
  • Very accurate electrical measurements, each unit is factory-calibrated
  • IOC – Independent Output Control
  • ZVS – Zero Voltage Switching


ZVS (Zero Voltage Switching)

 An important feature of the NETIO PowerPDU 8QS is ZVS (Zero Voltage Switching).

ZVS controls the exact time when the mechanical relay contacts close and open. The relay contacts switch the output on or off when the voltage crosses the zero level. 

  • In the long term, ZVS support reduces the product failure rate due to internal relay damage.
  • Since the relay switches when the sinusoidal voltage waveform crosses the zero level, negative effects of inrush current are significantly reduced.
  • The ZVS and PowerUp delay functions reduce the chance of circuit breakers tripping when power is restored after an outage.
  • ZVS extends the lifetime of connected equipment, especially in case of frequent on/off switching of devices that are not designed for that (such as switching power supplies).

>> Glossary: More about ZVS


The switching of outlets can be time-controlled by the Scheduler with a graphical interfaceScheduler (timed switching of individual outlets)

With the Scheduler (timer) function, each output can be individually switched on or off at specified times and days of week. The switching times are easily configured in a graphical interface.
  • Each output can have its own schedule
  • When a schedule is active, outputs can still be controlled with NETIO Cloud, the web interface and Open API
  • Scheduler functionality can be enabled/disabled (not edited) for each output from the NETIO Mobile 2 app.
  • Scheduler does not need an internet connection. However, a time source is needed – provided over the internet or, for example, by a local ADSL / WiFi router.
  • For special usage the Scheduler can be combined with PAB (Power Analyze Blocks):
    • Switching time is based on current sunrise/sunset based on your location
    • Whatever happend, defined output can be switched off on defined time (midnight for example).
    • Ask for more..

User can define output state after power restoring - PowerUp statePower-Up state

 For some applications, it is important to set the power output state immediately after the device is powered on (or the power is restored after a failure). With some machines it is important to avoid momentary switch-on or switch-off. This parameter therefore defines the behavior of the power output before the standard communication with a master system starts to work.
  • On
  • Off
  • LAST state restores the last state before the power was disconnected

Delay sequence when switching outputs on (PowerUp delay)

After a power outage, some electrical equipment can be switched on with a delay to avoid overloading and tripping circuit breakers. With the PowerPDU 8QS, use these parameters: “Power-Up state” = ON / LAST, and “Output PowerUp interval” = power-up delay before switching that particular output on.

>> Glossary: PowerUp state



WatchDog Ping + Power

PowerPDU 8QS is equipped with WatchDog PING (IP WatchDog) and WatchDog Power consumption (PAB).

  • WatchDog Ping continuously monitors whether a given process or a part of a system work as they should. If not, the WatchDog restarts the process. Can be used for all 8 outputs.
  • WatchDog Power is "Condition" & "Action" (PAB - Power Analysis Block & Rules) based autonomous system. It continuously monitors current (energy) of monitored device powered from any metered power output of NETIO PDU device.
    Only Output1 supports energy metering, so this feature can be used with Output1 only.

I forgot the password, how can I reset the product to factory defaults?

To reset the product to factory defaults, use the “RESET” button. When plugging in the device, hold the “RESET” button for about 10 seconds, until the yellow LED on the RJ45 jack flashes 3 times.  Factory settings will be restored (Load do defaults).

For the current procedure, see the supplied QIG (Quick Installation Guide) for the product.
It is available for download at this page as well as included in the product package.

Is it possible to specify in which state the output (power socket) will be after power-up?

Yes. When the PowerPDU is powered up, all outputs are set according to the configured PowerUp state (On / Off / LAST value). The parameter can be set in the web interface in the detailed configuration for each output.

The NETIO Mobile app cannot find the NETIO PowerPDU 8QS.

For Android mobile devices, please upgrade to NETIO Mobile 2. We are working on a mobile app for iOS devices.

Can PowerPDU 8QS restart a device remotely?

Remote restart is useful e.g. to control the power to a router, where a simple “power off” action would make it impossible to send the subsequent “power on” action. With the Restart – “Short OFF” action (can be invoked from the web interface), it is possible to switch off the power e.g. for 5 seconds, and then the PowerPDU switches it back on automatically, without further user intervention.

Can PowerPDU 8QS switch on an output at a specified time?

Yes, NETIO PowerPDU 8QS supports the Scheduler function.

Is it possible to control the device using an IoT cloud?

Yes. All NETIO products support the Open API. We are continuously publishing ANxx (Application Notes) that describe how to connect the product to various third-party systems.

NETIO PowerPDU 8QS can also be controlled using NETIO Cloud.

Does PowerPDU 8QS include a surge protector?

Yes, level 3 protection is included.

Is it possible to change the on/off state with a button on the device?

Yes. However, there is one button that controls all outputs. Press the “TGL” button 3x rapidly:

- If any outputs are On (1), they are switched Off (0)

- If all outputs are Off (0), all outputs are switched On (1)
