Relay

Low‑current Relay for Remote Device Control

Description
Relay is a compact, low-current wireless relay module designed to integrate with Ajax security systems, enabling remote control of various electrical devices. Installed inside an electrical panel or junction box, Relay supports both pulse and bistable modes, offering flexible control over equipment such as gates, locks, smoke cannons, roller shutters, or flood-prevention systems. With ultra-low power requirements and a secure Jeweller wireless connection, Relay brings smart automation into even the most space-constrained setups.


Key Features

  • Flexible Control Modes
    Supports both pulse (0.5–255 s adjustable) and bistable modes with normally open or normally closed contact states.
  • Wide Compatibility
    Works with all Ajax hubs and range extenders (ReX / ReX 2) over Jeweller communication.
  • Dry Contact Output
    Galvanically isolated from its own power supply, making it suitable for both low-voltage and household installations.
  • Miniature & Easy to Install
    Just 39 × 33 × 18 mm and 25 g: fits inside junction boxes, DIN holders, or electric panels. Installs in under a minute via QR code pairing.
  • High Relay Lifespan
    Designed for at least 200,000 switching cycles.
  • Secure & Reliable Wireless Communication
    Two-way encrypted AES communication over Jeweller, supports frequency hopping and delivers commands in ~0.15 s with adjustable scan intervals (12–300 s).
  • Extensive Coverage
    Up to 1,000 meters range in open space to the central Ajax hub or repeater.
  • Robust Operation
    Operates between –20°C and +64°C, up to 85% humidity, IP20 casing, with anti-sabotage, jamming detection, and remote testing capabilities.
