NETIO PowerCable IQRF 901x is a smart power extension cable that communicates over the IQRF LPWAN network (868 MHz). The 230V/16A electrical socket features accurate electricity metering (A, V, W, TPF, kWh, Hz) and can be switched on and off with full IQRF Interoperable support.

With a Smart connect QR code, PowerCable IQRF can be connected to the IQRF wireless network. Then, the DPA protocol can be used to control the output or read the measured values (electrical voltage [V], current [A], energy [Wh], output power [W], grid frequency [Hz], True Power Factor).



NETIO PowerCable IQRF 901x, a smart wireless power socket for lightweight industrial applications, is an ideal solution for remote control and metering of 230V power sockets outside electrical cabinets.

Communication over 868 MHz can reach hundreds of meters; the range can be extended with repeaters (MESH). PowerCable IQRF is constantly powered, so it also acts as a message repeater in the IQRF MESH network.

An important feature for light industrial use is ZCS (Zero Current Switching). This feature ensures that the relay is switched when the current passes through zero level. This significantly extends the relay lifetime. PowerCable IQRF 901x can be used at ambient temperatures from -10 to +65°C.

The socket can be controlled over the wireless network and the measured values can be read by any other IQRF product in the same network via the DPA interface. PowerCable IQRF supports the control methods and formats of variables defined by the IQRF Alliance.

IQRF Interoperable

PowerCable IQRF 901x supports the “IQRF Interoperable” DPA standard for sensors and I/O devices.  The product is based on the TR-76D module and allows firmware upgrades over the wireless network.

The output outlet state can be checked or written as a standard I/O for output no. 1. Sensor values are read using standard IQRF Interoperable functions (see IQRF-StandardSensor documentation).

IQRF is wireless LPWAN managed by IQRF Alliance

IQRF is a wireless LPWAN (Low Power Wide Area Network) operating in the 868 / 915 MHz (ISM) band, managed by the IQRF Alliance. The network can work as a mesh and can transfer small volumes of data at surprisingly large distances.

Since 2018, a DPA interface for standard sensors and I/O is defined under the name IQRF Interoperable. This means that measured values can be made available over an IQRF MESH network without a special configuration.

The IQRF standard was developed in the Czech Republic; thanks to excellent radio performance and overall reliability, this RF network is used by more than 100 companies in Central Europe.

  • Packet-oriented communication, max. 64B / packet
  • Range: hundreds of meters in free space, tens of meters indoors per hop, up to 240 hops per packet
  • Very low power consumption: sub-μA standby mode, max. 15 μA in receive mode
  • RF bitrate: approximately 20 kb/s


Power measurements

NETIO PowerPDU 4C is small PDU with power measurement and IEC-320 outputs

NETIO PowerCable IQRF 901x measures electrical parameters. The measured values are transmitted to the RF network. NETIO PowerCable IQRF 901x measures with accuracy better than 1%.

  • Current [A]
  • Output power [W]
  • Energy [Wh]
  • TPF (True Power Factor)
  • Voltage [V]
  • Grid frequency [Hz]

PowerUp state

User can define output state after power restoring - PowerUp state

For some applications, it is important to set the correct state of a power output immediately after power is turned on (or restored). The “PowerUp state” parameter defines the behavior of the 110/230V outlet just after power is restored, before the standard communication with the master system is established.

  • On
  • Off
  • LAST state restores the last state before the power was disconnected

For PowerCable IQRF 901x, the value is set with commands in the IQRF IDE.

ZCS (Zero Current Switching)

An important feature of NETIO PowerPDU 4C is ZCS (Zero Current Switching).

An important feature of NETIO PowerCable IQRF 901x is ZCS (Zero Current Switching). ZCS means that the control relay switches the output power outlet on or off when the current crosses the zero level.

  • Thanks to ZCS, the device can control switching power supplies (servers, computers and other IT equipment) up to the maximum rated power.
  • Using ZCS (Zero Current Switching) to switch on the outputs reduces the chance of a circuit breaker tripping when power is restored after an outage.
  • Since the relay switches when the sinusoidal current curve crosses the zero level, negative effects of inrush current are significantly reduced.
  • ZCS significantly reduces EMC interference generated by switching the 230V output on and off.
  • In the long term, ZCS reduces the product failure rate due to internal relay damage.
  • 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).
  • When a load is switched several times per day, ZCS puts less stress on the connected equipment and saves maintenance costs (power supply replacements for frequently switched equipment).

>> ZCS (Zero current switching)


IOC (Independent Output Control)

NETIO PowerPDU 4C can be used for professional applications, such as powering servers.

NETIO PowerCable IQRF 901x is suitable for professional applications. For example, with machines that take a long time to calibrate themselves after power-on, it is important to avoid momentary power switch-off or switch-on.

Output control is therefore completely independent from the IQRF network communication subsystem. The on/off status of the output outlet is not affected by any disconnection, internal device reboot or firmware upgrade.

Does PowerCable IQRF 901x have a Web interface?

No. IQRF products are configured using commands or the IQRF IDE utility for Windows.

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

No. The button on the PowerCable IQRF device is only used to bond with (connect to) the IQRF network.

My IQRF network stopped working, I want to connect PowerCable IQRF 901x to another IQRF WiFi network.

This is possible. Disconnect (unbond) the device in the network settings (Gateway) or with the button (IQRD standard – power up the device with the button pressed). Then, the device can be connected to another IQRF network (it will receive a new address).

Is it possible to control the PowerCable IQRF 901x outputs using a mobile app?

Not without an extension. Many Web gateway applications are being developed for the IQRF Interoperable standard, so mobile applications can be expected soon, too. 

Can PowerCable IQRF 901x switch on the output at a specified time?

No, at least not without some intelligence implemented in the IQRF network.

Is it possible to modify the product for a custom application?

Yes. For the WiFi version of the product, we offer customized versions under the “NETIO COBRA” program. It is possible to provide customized M2M protocols, UDP discover devices, custom device and packaging labels, and so on.

Available customizations of the IQRF version are more limited; please contact us for details.

I have just unpacked the PowerCable IQRF, how do I configure it?

See the manual for the up-to-date procedure (download here).
Start the bonding process in the IQRF IDE or the IQRF gateway and press the button on PowerCable IQRF (the yellow LED lights up). To disconnect from the IQRF network, go to the network settings.
