NETIO PowerPDU 4KS is a smart PDU (Power Distribution Unit) with 4 metered & switched power outputs (4x IEC-320 C13) and 1x DI (Digital Input). PDU measures power consumption (A, kWh, TPF, W, V, Hz) and switching On/Off each power output individually. Device supports local Ping & Power WatchDog and Scheduler functions.
PowerPDU 4KS can be mounted in rack cabinets – horizontally, vertically, or as a 1U device. Each output can user switch manually over the web, the NETIO cloud service, or with a Mobile App (Locally or via NETIO Cloud). The DI (Digital Input) can control the outputs or count S0 pulses (ext. power metering).PDU supports Open API for 3rd party integration (http JSON, Modbus/TCP, SNMP, MQTT-flex, Telnet, ...).
With the NETIO Cloud service, the outputs can be controlled from anywhere. The NETIO Cloud is paid service with welcome credit for new connected devices. It’s SSL secured cloud solution, servers located in Europe. AV drivers make it easy to connect NETIO sockets to professional Audio/Video control systems such as Neets, Crestron, Control4 etc.
The NETIO Mobile 2 app controls each output individually over LAN (local network) or the NETIO Cloud service.
NETIO Cloud is a TLS-secured service for controlling the outputs from anywhere (Web or Open API).
Open API allows controlling the outputs over the network using various protocols (http XML/JSON, Modbus/TCP, MQTT, SNMP, Telnet and more... ).
AV drivers make it easy to connect NETIO sockets to professional Audio/Video systems such as Neets, CRESTRON, Control4 and more.
Professional product
NETIO PowerPDU 4KS is suitable for industrial applications. The product works in a wide temperature range (–20°C to +65°C), supports firmware upgrades over the web, remembers the last socket states before being powered off, and its relays switch at zero current.
A power-on delay can be configured for each output. In this way, the outputs can be switched on in a sequence after a power outage.
Open API: Supported M2M protocols
The open API can use one protocol at a time, chosen from among the supported M2M protocols:
- Modbus/TCP AN27, AN22
- MQTT-flex AN40
- Telnet AN10
- http URL API AN19, AN29
- JSON over HTTP (default) AN21, AN30, AN42
- http Push JSON
- http Push XML
- XML over HTTP AN20, AN31
- SNMP v1 AN11, AN41
- SNMP v3
The SNMP protocol can be always used in parallel to outher APIs.
Regardless of the Open API used, the device can be always controlled from its web interface and from the NETIO Cloud service. The customer may use one Open API protocol and the NETIO Cloud service simultaneously.

Typical applications
- In IT, the smart PowerPDU 4KS is typically used to measure & distribute electricity in a 19" rack (cabinet) in a data center.
- The connected appliances can be restarted from the web interface (each output can be switched on / off or power-cycled).
- Powered devices can be restarted autonomously by PING or Power consumption Watchdog
- The outputs can be controlled with the Open API (JSON, Modbus/TCP, SNMP, MQTT-flex, Telnet, ...)
- The device can work with various 3rd party programs and applications (Open API)
- The outputs of several NETIO products can be controlled using the NETIO Mobile 2 app (Andriod & iOS)
- The outputs of multiple devices can be controlled centrally using the NETIO Cloud service (for a fee).
HTTPs
NETIO PDUs have implemented HTTPs security.
The HTTPs is supported both for the WEB interface and for Open API protocols (JSON, XML). A customer certificate can be used.
NETIO Cloud
The product can be connected to NETIO Cloud. Control hundreds of outputs from a single web screen. NETIO Cloud is an ideal solution for remote control and restarting. The NETIO Cloud service is a paid service.
- All devices produced by the NETIO products company can be connected to NETIO Cloud.
- With every added device you receive free "Welcome Credit"
- Devices connected to the service can be controlled securely from anywhere over the Web (HTTPs).
- NETIO Cloud can be used in parallel with another Open API protocol.
- Communication with the Cloud service is secured (port 8883 - MQTTs - TLS)
- NETIO Cloud uses a separate Open API (MQTTS protocol) to control all devices linked to a given user account.
Electrical measurements
NETIO PowerPDU 4KS measures electrical parameters on 4 outputs + 1 total channel:
Measured values are displayed in the web administration interface and at the same time are accessible via Open API protocols. NETIO PowerPDU 4KS measures with accuracy better than 1%.
- Output 1
- Output 2
- Output 3
- Output 4
- All output together (power inlet)
>> More about electrical measurements
DI (Digital Input)
A digital input (DI) can be used to control any of the outputs(s) or count S0 pulses. The DI can be connected to a button (dry contact) or used as a S0 pulse counter for reading energy consumption from an external electricity meter.
The DI state and the S0 counter value are shown in the web interface and accessible over Open API.
- Digital input (DI): 1x input (contact) + S0 counter (4 bytes)
- Power for DI: 12V power

Industrial product quality
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 (–20°C to +65°C)
- PowerUp state – defined output state after power-up
- PowerUp delay (outputs switched on after a delay)
- Firmware upgradeable over the web, backwards compatibility
- IOC - Independent Output Control
- ZCS – Zero Current Switching
- Outputs can be switched on/off for a short (configurable) time
ZCS (Zero Current Switching)
An important feature of NETIO PowerPDU 4KS is ZCS (Zero Current Switching). ZCS controls the exact time when the mechanical relay contacts close and open. The relay contacts switch the output on or off when the current crosses the zero level.
- In the long run, ZCS support reduces the product failure rate due to internal relay damage.
- Since the relay switches when the current waveform crosses the zero level, negative effects of inrush current are significantly reduced.
- The ZCS and PowerUp delay functions reduce the chance of circuit breakers tripping when power is restored after an outage.
- ZCS 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).
Power-Up state
For some applications, it is important to set the power socket 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 110/230V output power socket 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
After a power outage, some electrical appliances can be switched on with a delay to avoid overloading and tripping circuit breakers. With the PowerPDU 4KS, use these parameters: “Power-Up state” = ON / LAST, and “Output PowerUp interval” = power-up delay before switching that particular output on.
Week Scheduler (timed switching of individual outlets)
- 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..

WatchDog Ping + Power
PowerPDU 4KS 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 4 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. Can be used for all 4 outputs.
