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
- JSON ovet 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 one of other APIs.
Regardless of the Open API used, the PowerDIN 4PZ can be always controlled from its web interface and from the NETIO Cloud service at the same time. The customer may use one Open API protocol and the NETIO Cloud service simultaneously.

Typical applications
- The PowerDIN 4PZ LAN/WiFi electricity meter is typically used for electricity metering and distribution in a DIN electrical cabinet.
- Remote energy consumption monitoring in one or two circuit branches.
- Connecting the pulse output of a 3-phase electricity meter to In1 or In2 in order to measure electricity consumption above 16A.
- Each output can be switched on/off or power-cycled (e.g. to restart all appliances connected to the same circuit branch) from the web interface or the NETIO Cloud service.
- Controlling the charging of e-bikes, boats and other appliances up to 3.6 kW (230V/16A).
- Controlling the outputs using Open API (JSON, Modbus/TCP, SNMP, MQTT-flex, Telnet, ...)
- Integration with various third-party programs and applications.
- Controlling the device from the NETIO Mobile 2 app as long as the app is connected to the same network.
- The NETIO Cloud service, provided for a fee, enables central control of outputs of multiple devices in various locations.
I/O = Relay outputs & Digital Inputs for buttons (Dry contact) + S0 pulse counter
- Power Outputs 1 & 2 are two independently-metered 230V channels. Each power output can be switched on and off with a built-in ZCS relay.
- DO (Digital Outputs) 3 & 4 are relay outputs. General-purpose NO/NC relay contacts can be controlled remotely. These two outputs do not support ZCS, and are not connected to the supply voltage.
- DI (Digital Inputs) In1 & In2 can be used to connect any dry contact. DI input states are shown in the Open API. In addition, each input includes an S0 pulse counter for monitoring a water or electricity meter.
| Output | Measurements | Switching | Max. voltage/ current |
| Out 1, Out 2 | A, W, Wh, TPF, V, Hz | Relay (ZCS) | 110-230VAC / 16A |
| Out 3, Out 4 | - | Relay | 110-230VAC / 2A 48VDC / 2A |
LAN / Wi-Fi
The product can be connected to one network only at a time. When a live RJ45 (Ethernet) connection is detected, the product uses the LAN. When the RJ45 cable is disconnected or the link layer is inactive, the product switches to WiFi.
For the WiFi connection, the product uses an internal antenna. When installed a metal cabinet, its range will be very limited.
The WiFi connection can be configured using the AP mode.
- 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. The mode switch button is located under the top panel.
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.
Industrial product quality
- Open M2M API
- Wide range of operating temperatures, accurate measurements in the entire range
- PowerUp state – defined output state after power-up (remembers the last state)
- PowerUp delay (outputs switched on after a delay). In this way, the outputs can be switched on in a sequence after a power outage
- Firmware can be upgraded over the Web, configuration can be imported and exported .
- IOC - Independent Output Control
- ZCS – Zero Current Switching (outputs 1 and 2)
- Energy metering tracks the energy flow in both directions separately (with two separate kWh counters); an additional, user-resettable counter is also provided .
ZCS (Zero current switching)
NETIO PowerDIN 4PZ can switch the metered outputs 1 and 2 when the immediate current crosses the zero level. ZCS significantly extends the lifetime of relay contacts when switching “problematic” appliances, such as LED lights or electric motors.
- ZCS (Zero Current Switching) means that the relays switch the outputs (1 and 2) at the moment when the current crosses the zero level.
- In the long run, ZCS support reduces the product failure rate due to internal relay damage.
- ZCS reduces the negative effects of a high inrush current.
- Thanks to ZCS, the device can control switching power supplies (servers, computers and other IT equipment) up to the maximum rated power.
- 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
Power-Up sequence (switching outputs on with a delay)
When the power is restored after an outage, electrical appliances can be switched on in sequence with certain delays in order to avoid an overload and the tripping of circuit breakers. With the PowerDIN 4PZ, use these parameters: “Power-Up state” = ON / LAST, and “Output PowerUp interval” = power-up delay before switching that particular output on.

NETIO PowerDIN 4PZ measures electrical parameters for outputs 1 and 2 separately. Measured values are displayed in the web administration interface and are accessible via M2M protocols. PowerDIN 4PZ measures with accuracy better than 1% in the entire operating temperature range.

Use cases for the remotely controlled electricity meter
- Electricity consumption monitoring for machines in the manufacturing industry
- Electric car slow charging control
- Switching power outputs on and off with a mobile app
- Remote consumption metering and output control from NETIO Cloud
Scheduler function (calendar)
- 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..
>> More about Scheduler function
WatchDog Ping + Power
PowerDIN 4PZ 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.
Only Output1 and 2 supports energy metering, so this feature can be used with Output1 and 2 only.
