AirShield 100-240VAC Relay: wireless mains voltage switching
With the AirShield 100-240VAC Relay you switch mains voltage on or off wirelessly from your AirShield system. Ideal for lighting, ventilation, pumps or other fixed appliances that you want to be able to switch remotely.
This compact relay module switches the live conductor via an internal relay up to 13 A and measures voltage, current and energy consumption at the same time. With built-in protection against overheating, overload and overvoltage, you can switch with confidence.
Why the AirShield 100-240VAC Relay
Switching mains voltage
One relay output (NO or NC) for 100 to 240 VAC up to 13 A. You switch the live conductor, while the neutral remains connected through.
Insight into consumption
The module measures voltage, current and energy consumption, so you can see how much a connected device uses.
Triple protection
Built-in protection against overheating, overload and overvoltage, for safe switching of fixed installations.
Stable and encrypted
Two-way communication on 868 MHz with AES128 and frequency hopping, with a range of up to approximately 1,200 metres in open terrain.

Which switch do you need?
Do you want to control something from your AirShield system? The 7-24 VDC Relay switches low voltage, such as a gate or lighting. The 100-240VAC Relay switches mains voltage in a fixed flush-mounted installation and measures consumption at the same time. The Smart Plug is the simplest: you plug it in between the socket and the appliance.
| Model | Switches | Max load | Measuring | Mounting | Ideal for |
|---|---|---|---|---|---|
| 7-24 VDC Relay | Low voltage 7-24 VDC | Up to 5 A | No | Built-in or wall-mounted | Gate, lighting, low voltage |
| 100-240VAC Relay | Mains voltage 100-240 VAC | Up to 13 A | Voltage, current, consumption | Built-in or wall-mounted | Fixed switching (flush-mounted) |
| Smart Plug | Mains voltage (socket) | Up to 16 A | Voltage, current, temperature | Plug (plug-in) | Switch a device smartly in no time |
All three switch wirelessly on 868 MHz with two-way communication and AES128, and work with the AirShield hub. The 100-240VAC Relay and the Smart Plug also measure energy consumption.

Frequently asked questions
What can I switch with this?
Fixed appliances on mains voltage (100 to 240 VAC) up to 13 A, such as lighting, ventilation or a pump. The module measures consumption at the same time.
What is the difference from the Smart Plug?
You install this relay permanently (flush or wall mounting). The Smart Plug simply goes between the socket and the appliance, with no installation.
Is connecting it safe?
The module has protection against overheating, overload and overvoltage. We recommend having a qualified professional connect mains voltage.
Can I see the consumption?
Yes. The relay measures voltage, current and energy consumption, so you can see what a connected device uses.
