RELAY

The AJAX Relay (distinct from WallSwitch) is a compact wireless module with potential-free dry contacts for remote control of low-voltage DC circuits (7-24V), ideal for switching electric locks, gates, shutters, or modem restarts in automation scenarios.
It operates in bistable (on/off toggle) or pulse modes (0.5-255s duration), features voltage monitoring with protection (6.5-36.5V range), and communicates via Jeweller protocol up to 1000m with tamper/jamming detection.
