Overview
For secure, flexible equipment control in security and monitoring applications, the AJAX Remote Control Low Current Relay with Dry Contacts delivers reliable switching without compromising system integrity. The AJAX relay’s SPDT dry contact isolates loads from the device’s power, enabling safe control of both low-voltage and household circuits — ideal for intrusion panels, access control gates, CCTV switchovers and industrial automation. Operating on 7–24 V and offering configurable pulse durations from 1 to 255 seconds, it supports timed operations and bistable control to match diverse installation needs. Two-way radio communication up to 1000 meters (with support for five signal range extenders) and a compact 39×33×18 mm form factor let you deploy the relay in junction boxes, electrical panels or DIN-mounted enclosures while maintaining robust connectivity. Low power consumption, fast command delivery (~0.15 s) and simple QR-code pairing via the Ajax app reduce installation time and total cost of ownership. Add this AJAX relay to your security, surveillance, or monitoring projects for dependable remote switching — contact sales or add to cart to begin integration.
