PowerDIN 4PZ is a dual 110/230V max 16A electricity meter with LAN/WiFi and I/O. Web control, support for NETIO Cloud, Open API.

NETIO PowerDIN 4PZ connects to the network using a RJ45 jack (Ethernet) or WiFi (2.4 GHz – internal antenna).

Outputs 1 and 2 feature accurate electricity metering (110/230V, max 16A). Moreover, the outputs can be switched on and off with a Zero Current Switching relay.

Outputs 3 and 4 feature NO/NC relay contacts.  Digital inputs 1 and 2 with 4-byte pulse counters can be used to connect momentary switches (dry contact) or S0 outputs of electricity, water or similar meters.

Using the product’s web interface, measured values can be read and the 4 outputs can be switched on or off.

Open API enables integration into third-party systems using a wide range of protocols (JSON, Modbus/TCP, SNMP, MQTT, Telnet, ..).

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

Use cases for the remotely controlled electricity meter

  • Electricity consumption monitoring for machines in the manufacturing industry
  • Electric car AC charging control
  • Switching power outputs on and off with a mobile app
  • Consumption metering and socket control from NETIO Cloud


Open API

The NETIO PowerDIN 4PZ smart electricity meter can be controlled over the Web and the NETIO Cloud at the same time. For Open API communication, one M2M protocol can be chosen at a time from among the following:

  • Modbus/TCP
  • MQTT-flex
  • Telnet
  • URL API (http get)
  • JSON over HTTP
  • XML over HTTP
  • SNMP v1
  • SNMP v3
  • HTTP(s) Push JSON
  • HTTP(s) Push XML

The SNMP protocol can be always used in parralel to other APIs.

Documentation for the protocols is available at the manufacturer’s website. The ANxx Application Notes provide useful deployment guidance.


Digital inputs for S0 / momentary switch (dry contact)

The In1 and In2 digital inputs can be used to connect dry contacts that can then be monitored using the Open API. In addition, each input includes an S0 pulse counter for monitoring the consumption with a water meter, an electricity meter or a similar meter.

Industrial product quality

The PowerDIN 4PZ LAN/WiFi dual electricity meter is intended for professional use.

  • Designed for mounting on a DIN rail (6 units).
  • 2-point factory calibrated (temperature compensation).
  • PowerUp state – the state of the outputs after the device is powered up is configurable (On/Off/Last).
  • ZCS – for switching an appliance on and off more frequently than a few times a day, ZCS (Zero Current Switching) support becomes important in the long term. ZCS makes sure that the relays at outputs 1 and 2 switch when the immediate current is zero.
  • IOC function (Independent Output Control) – states of outputs are not affected by LAN connection failures, network layer restarts, or firmware upgrades.


Scheduler function (calendar)

With the Scheduler function, each output can be switched on and off automatically at pre-defined times and days-of-week. A schedule is useful for saving energy and periodic restarts of other equipment.



NFC Config = quick WiFi connection setup

With the NETIO Mobile2 app and a NFC-capable phone, the product can be connected to a WiFi network in 60 seconds.

For WiFi setup without NFC, the product features a built-in WiFi AP as well as a wizard to guide you through the selection of a WiFi network and configuring the connection.
