The maximum resistive load of the relay is 3 kW. If an inductive or capacitive load is connected, the maximum switching current drops to 8 A.
Ajax Wall Switch Relay
R700
Relay is a dry contact relay to control a power supply remotely. The relay’s dry contacts are electrically isolated to the power supply circuit of the device. Relay can be used in both low-voltage and domestic power grids. The device features two types of protection: voltage and temperature.
Description
WallSwitch is a power relay to control 110/230 V~ power supply remotely. The relay power supply is not galvanically isolated with terminal blocks; therefore, WallSwitch switches only the power received at the power supply terminal blocks. The device has an energy consumption meter and features three types of protection: voltage, current, and temperature.
WallSwitch controls the power supply of electrical appliances connected to the circuit with a load of up to 3 kW using Ajax apps, automation scenarios, the function button on the relay, and by pressing Button.
WallSwitch is connected to the Ajax system via the secure Jeweller radio protocol. The communication range is up to 1,000 meters in an open space. The device works only with Ajax radio signal range extenders and hubs.
Operating principle
WallSwitch is a power relay of the Ajax system. The relay is installed in the electrical circuit gap to control the power supply of devices connected to this circuit. The relay can be controlled via the function button on the device (by holding it down for 2 seconds), the Ajax app, Button, and automation scenarios.
WallSwitch switches one single pole of the electrical circuit — the phase. In this case, the neutral is not commuted and remains closed.
WallSwitch can operate in bistable or pulse mode (pulse mode is available with firmware version 5.54.1.0 and higher). The pulse duration can be set in pulse mode from 1 to 255 seconds. The operating mode is selected by users or PRO with admin rights in Ajax apps.
The user or PRO with administrator rights can also set the normal state of the relay contacts (the function is available for WallSwitch with firmware version 5.54.1.0 and higher):
- Normally closed — the relay stops supplying power when activated and resumes when deactivated.
- Normally open — the relay supplies power when activated and stops when deactivated.
WallSwitch measures the current, voltage, the amount of energy consumed by electrical appliances, and the power they consume. This data, along with other operating parameters of the relay, is available in the device States. Relay states update frequency depends on Jeweller or Jeweller/Fibra settings; the default value is 36 seconds.
Automation scenarios
Ajax’s scenarios offer a new level of security. With them, the security system not only notifies about threats, but also actively resists them.
Scenario types with Relay and examples of usage:
- By alarm. Lighting is switched on when an opening detector activates the alarm.
- By security mode change. The electric lock is automatically blocked when the object is armed.
- By schedule. The irrigation system in the yard is switched on according to the schedule at the specified time. Lighting and TV are switched on when the owners are away, so the house doesn’t seem empty.
- By pressing Button. Switching on night lighting by pressing the smart button.
- By temperature. The heating is turned on when the temperature in the room is lower than 20°C.
- By humidity. The humidifier is switched on when the humidity level drops below 40%.
- By CO₂ concentration. Supply ventilation is turned on when the carbon dioxide concentration level exceeds 1000 ppm.
