Socket (type F) operates with Ajax hubs only and does not support connecting via ocBridge Plus or uartBridge integration modules.
Ajax Socket (Type F)
R1420
Socket (type F) is a wireless indoor smart plug with the power-consumption meter for indoor use.
Description
Socket (type F) is a wireless indoor smart plug with the power-consumption meter for indoor use. Designed as a European plug adapter (type F), Socket (type F) controls the power supply of electrical appliances with a load of up to 2.5 kW. Socket (type F) indicates the load level and is protected from overload. Connecting to the Ajax system via a secured Jeweller radio protocol, the device supports communication at a distance of up to 1,000 m in line of sight.
Use scenarios to program actions of automation devices (Relay, WallSwitch, LightSwitch, WaterStop or Socket (type F)) in response to an alarm, Button press, a schedule or temperature, humidity, CO2 concentration levels change. A scenario can be created remotely in the Ajax app.
Operating Principle
Socket (type F) switches on/off the 110–230 V~ power supply, opening one pole by the user command in the Ajax app or automatically according to a scenario, Button press, a schedule.
Socket (type F) is protected against voltage overload (exceeding the range of 184–253 V~) or overcurrent (exceeding 11 A). In case of overload, the power supply switches off, resuming automatically when voltage restored to normal values. In case of overcurrent, the power supply switches off automatically, but can only be restored manually by the user command in the Ajax app.
The maximum resistive load is 2.5 kW. When using inductive or capacitive loads, the maximum switching current is reduced to 8 A at 230 V~.
Socket (type F) with firmware version 5.54.1.0 and higher can operate in pulse or bistable mode. With this firmware version you can also select the relay contact status:
- Normally closed — Socket (type F) stops supplying power when activated, and resumes when turned off.
- Normally open — Socket (type F) supplies power when activated, and stops feeding when turned off.
Socket (type F) with firmware version below 5.54.1.0 only works in bistability mode with a normally open contact.
How to find out the firmware version of the device?
In the app, users can check the power or amount of energy consumed by electrical appliances connected via Socket (type F).
At low loads (up to 25 W), current and power consumption indications may be displayed incorrectly due to hardware limitations.
