Ajax Relay (EU)

Product Ref: 38204.19.NC1

Relay is a wireless, low-voltage relay featuring potential-free (dry) contacts. Use Relay to remotely switch on/off appliances powered by a 7–24 V DC source. Relay can operate both in pulse and bistable mode. The device communicates with a hub via Jeweller radio protocol. In the line of sight, the communication distance is up to 1,000 m.
The Relay contacts are not galvanically connected to the device itself, so they can be connected to the input control circuits of various equipment to imitate a button, toggle switch, etc.
Main features:

  • Operates from 7-24 V DC voltage sources
  • Rated for 200,000 switch ons
  • Maximum load of 5A at 36V DC / 13A at 230V AC
  • Installed into electric switchboard or junction box
