M2DWIFI-2 / M2DWIFI-TCP / TCIDWIFI-TCP Wi-Fi energy meters with remote disconnect relay
Country: Spain · Model: M2DWIFI-2 / M2DWIFI-TCP / TCIDWIFI-TCP
The M2DWIFI-2, M2DWIFI-TCP and TCIDWIFI-TCP Wi-Fi meters are read remotely and have a built-in power relay for switching off the load. The single-phase models are rated 5(60) A and the three-phase one 10(100) A. Data goes to the Smartenergy cloud platform with a web portal and a mobile app.

Description
M2DWIFI-2 takes 2 DIN-rail modules, works from 165–265 V AC, has an accuracy of 1 %, Wi-Fi 802.11 b/g/n and a built-in switch for remote disconnection up to 80 A. It measures current, voltage, active power and energy, stores the consumption history and signals anomalies. The 3-module M2DWIFI-TCP adds Ethernet and RS485 and a second current input through an external 60 A/333 mV transformer, so load and generation can be counted separately. It calculates the power factor and the THD of current and voltage, synchronizes date and time, has a web interface over HTTP and firmware update over the network (FOTA). TCIDWIFI-TCP takes 7 modules, is powered from 3×165–265 V AC, has a relay per phase up to 100 A, Wi-Fi, Ethernet and RS485 interfaces (Modbus RTU and Modbus TCP), measures maximum and minimum values and THD, and also accepts a 60 A/333 mV transformer.
How to choose
A single-phase network and a small load suit M2DWIFI-2, and when RS485, Ethernet and a second current channel are needed, take M2DWIFI-TCP. For a three-phase incomer there is TCIDWIFI-TCP for 10(100) A. If MID-certified three-phase metering without Wi-Fi is needed, look at TCIDL-MID, and for single-phase DIN-rail metering without a relay, M1DL1-MID or M2DL1.

FAQ
Can the load be switched off remotely?
Yes, all models have a built-in power relay. In M2DWIFI-2 the switch is rated up to 80 A, in TCIDWIFI-TCP there is one relay per phase up to 100 A, and control is through the web portal and the app.
What interfaces does M2DWIFI-TCP have?
Wi-Fi, Ethernet and RS485, as well as an HTTP web interface. The firmware is updated over the network (FOTA).
What is the 60 A/333 mV transformer input for?
The second channel measures current through an external transformer, so, for example, consumption and generation are monitored separately.
Which standards do these meters comply with?
UNE/EN 62052-11, UNE/EN 62053-21, 62053-22, 62053-23, UNE/EN 61010 and DIN 43864.
