Ajax Relay – Wireless Low-Voltage Controller

Transform your property into a true smart home by controlling your gates, roller blinds, and electronic locks directly from your smartphone. The Ajax Relay is a miniature, wireless low-voltage controller designed to remotely switch various low-voltage electrical devices on or off.

Dry Contact and Flexible Pulse Modes

The device operates using a dry (potential-free) contact, meaning its switching mechanism is galvanically isolated from its power source. This ensures it can safely interface with the control boards of various electronics. You can configure it to operate in a bistable mode (always on/always off) or a pulse mode (triggering a short signal between 0.5 and 255 seconds). Pulse mode is absolutely perfect for mimicking a button press to open electric gates or remote rebooting frozen internet routers.

Safety and Ultra-Compact Design

Measuring just 38 × 25 × 18 mm, the Relay is designed to easily fit inside standard electrical junction boxes, distribution boards, or directly inside gate motor enclosures. It is heavily protected against overvoltage (automatically cutting off below 6.5 V and above 36.5 V) and overheating (shutting down above 65°C). It receives commands securely via the Jeweller protocol up to 1,000 meters away.
