Ajax Relay, 12 V relay module

Ajax Relay

Ajax Relay is a wireless potential-free relay module for remote control of low-voltage electrical devices. It is designed for switching devices on or off via the Ajax security system app without carrying current itself – the relay simply switches the contact state.

• • Control of garage doors or garden gates

  • Opening magnetic and electric locks

  • Control of lighting or automation devices

  • Rebooting servers or network equipment

  • Switching heating or ventilation in low-voltage circuits

Key features:

• Dry contact (potential-free) relay – suitable for controlling various systems (e.g. doors, gates, automation)

• Can be set to pulse mode (e.g. 0.5 s to 15 s) or latching close/open

• Control via the Ajax mobile app, alarms, automation scenarios or manually from the app

• Compact – fits in an electrical panel or junction box

• Does not carry the load – switching only
