NETIO PowerPDU 4PS is a smart PDU (Power Distribution Unit) with four power outlets (4x IEC-320 C13). Each output can be switched on/off individually. NETIO PowerPDU 4PS can be mounted in rack cabinets – horizontally, vertically, or as a 1U device. Integration into third-party systems using various protocols (JSON, Modbus/TCP, SNMP, MQTT-flex, Telnet, ...) is easy thanks to the open API. 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.
NETIO PowerPDU 4PS can be configured with a web browser (allows output control, connection to NETIO Cloud, Open API communication settings, etc.).
NETIO PowerPDU 4PS does not support electrical measurements. Each output can be individually switched on/off or power-cycled. To switch the outputs on in a sequence, a power-up delay can be configured for each output.
The NETIO Mobile2 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 4PS 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 voltage.
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, AN37
- MQTT-flex AN40
- Telnet AN10
- http URL API AN19, AN29
- http JSON AN21, AN30, AN42
- http XML AN20, AN31
- SNMP v1 AN11, AN41
Regardless of the Open API used, the PowerPDU 4PS 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 4PS is typically used to 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).
- The outputs can be controlled with the Open API (JSON, Modbus/TCP, SNMP, MQTT-flex, Telnet, ...)
- The device can work with various third-party programs and applications (NETIO Drivery).
- The outputs of several NETIO products can be controlled using the NETIO Mobile 2 app (Android), as long as the app is connected to the same network.
- The outputs of multiple devices can be controlled centrally using the NETIO Cloud service (for a fee).

NETIO Cloud
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.
The paid NETIO Cloud service is operated by NETIO products a.s. as a support for manufactured equipment.
- All products manufactured by NETIO products can be connected to NETIO Cloud.
- The user can control connected devices securely via the web from anywhere (HTTPs).
- The first 3 years are free connection to the service thanks to the "Welcome credit".
- NETIO Cloud can be used in parallel with other Open API protocols.
- Secure device communication to the Cloud service (port 8883 - MQTTs - TLS)
- NETIO Cloud has its own Open API, which can be used to control all devices in a specific user account (MQTTS protocol).

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
- ZVS – Zero Voltage Switching
ZVS (Zero Voltage Switching)
An important feature of the NETIO PowerPDU 4PS 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).
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 4PS, use these parameters: “Power-Up state” = ON / LAST, and “Output PowerUp interval” = power-up delay before switching that particular output on.
Mobile App
PowerPDU 4PS can be controlled over the local network using the NETIO Mobile 2 app (for Android mobile devices).
- The mobile app can be used to control several PDU units and all their outputs
- The mobile device must be connected to the same LAN (connect the phone/tablet via WiFi).
- NETIO Mobile2 can scan the LAN and discover connected devices. WiFi connection to the LAN is required.
For the moment, NETIO Mobile 2 application is not available for iOS users. We recommend using third party apps:
- AN39 NETIO and third-party mobile apps for iPhone – iOS (URL API, Telnet, Modbus)
- AN38 NETIO and third-party mobile apps for Android (URL API, Telnet, Modbus)
PowerPDU 4C / 4PS comparison
NETIO offers two versions, PowerPDU 4C and PowerPDU 4PS.
“PowerPDU” designation (form factor) means that the product is intended for IT environment for installation in a 19” cabinet.
Accessories are available from the manufacturer to mount one 4C / 4PS unit (RM1) or two units side-by-side (RM2) into 1U of space in a 19” rack/cabinet. Other accessories allow mounting the product vertically, to the back, or to the side of the cabinet.
NETIO PowerPDU 4C is a PDU (Power Distribution Unit) with 4x IEC-320 C13 electrical outlets as outputs. Each output can be independently turned on or off and its consumption [Wh], current [A], TruePF and other parameters measured with a <1% accuracy.
PowerPDU 4C supports ZCS, includes a built-in 2x LAN ethernet switch and features a serial port (RS-232).
PowerPDU 4PS
NETIO PowerPDU 4PS is a PDU (Power Distribution Unit) with 4x IEC-320 C13 electrical outlets as outputs. Each output can be switched on/off individually. The 4PS model does not support electrical measurements.
