Description

The Ajax Relay (8EU) ASP is a remote control relay with a dry contact output that works in pulse or bistable mode. It connects to an Ajax system over the Jeweller wireless protocol, at a distance of up to 1000 m (3280.8 ft), and is set up and monitored in an Ajax app.

The relay runs on an external 7–24 V⎓ power supply and does not supply additional power to devices connected to it. Its contact can be set to normally open or normally closed, and it can be triggered by automation scenarios. It suits indoor or outdoor use when installed in a hermetically sealed enclosure. Mounting on a DIN rail with the separately sold DIN Holder is recommended.

Key features:

  • Jeweller wireless communication with two-way data exchange, block encryption featuring a dynamic key, and frequency hopping against radio interference and jamming
  • Pulse and bistable modes, with pulse duration adjustable from 0.5 to 255 s
  • Scenarios by arming/disarming, schedule, alarm, temperature, or by touching LightSwitch / pressing Button; humidity and CO₂ concentration scenarios are available when LifeQuality Jeweller is added to the system
  • Maximum resistive load of up to 5 A at 24 V⎓ or up to 13 A at 110–230 V~, and inductive/capacitive load of up to 3 A at 24 V⎓ or up to 8 A at 110–230 V~
  • Voltage protection with automatic shutoff outside 6.5–36.5 V⎓, plus overheat protection, and device authentication against spoofing, with connection loss detected after 36 s
  • IP20 protection, operating temperature of -10 … +64 °C (14 … 147.2 °F) and humidity of up to 75%
  • Black housing of 1.54″ × 1.3″ × 0.71″ weighing 25 g (0.882 oz), supplied with double-sided adhesive tape and a quick start guide
