What will the outputs power?
How many outputs drive a motor or contactor?One snubber per output like this, out of 44

Motors, pumps, contactors and LED drivers create voltage spikes every time they switch. The snubber absorbs them, so the device doesn't drop offline or restart, and the relay contacts last longer.

Who it’s for

For anyone building or renovating who wants to centralize control in the electrical panel instead of behind every switch: four circuits of up to 16 A each (40 A in total), with power metering on every channel and a small screen for manual control. Suitable for lighting, outlets, the water heater, air conditioners and pumps. For shutters in the panel, Pro 2PM or Pro Dual Cover is a better choice.

What to know before installing

  • Requires space on the DIN rail in the electrical panel (just over two modules).
  • Each channel handles up to 16 A. For a water heater or a large air conditioner, check the current first.
  • With a motor, fan or exhaust fan load, connect a snubber in parallel with the load.
  • Wi-Fi or Ethernet connection.

FAQ

Do the wall switches keep working?

Yes. You connect them to the relay’s inputs, and they switch the channels even without internet.

Can I use it as a Shabbat timer?

Yes. Set schedules for each channel; they’re stored on the device itself. See smart Shabbat timers.

How is it different from the Pro 1PM?

The Pro 1PM controls one circuit and the Pro 4PM controls four, with a screen and in less space than four separate relays.
