Which device is the SSR Add-on compatible with?

It is an accessory for The Pill by Shelly. It connects through the intermediate 5-Terminal Add-on adapter, sold separately; it does not mate directly with The Pill.

What loads can the two outputs switch?

Each channel (LOAD1 and LOAD2) switches a direct-current load of up to 30 V and 300 mA, for example LED strips, small fans, solenoids or micro-motors.

Can I switch 230 V AC mains with this module?

No. The outputs are only for low-voltage direct current up to 30 V DC. For 230 V AC you must use a mains-rated relay, not this accessory.

What are the module's dimensions and weight?

The black housing measures 36 x 31 x 11.5 mm and weighs 12 g, making it easy to place inside junction boxes or compact enclosures.

Does the relay make noise when switching?

No. As a solid-state relay, switching is electronic with no moving contacts, so it is silent and of mechanical wear over time.

About this product

The Shelly SSR Add-on is a compact accessory module for The Pill by Shelly that adds two solid-state relay outputs (LOAD1 and LOAD2) for switching direct-current loads of up to 30 V and 300 mA per channel.<br><br>Both outputs are galvanically isolated and act as potential- contacts, switching silently and without mechanical wear, which suits them for LED strips, small fans, solenoids and other low-voltage DC consumers. The module also provides one configurable digital input/output, IO3, at a 3.3 V logic level.<br><br>The black housing measures only 36 x 31 x 11.5 mm and weighs 12 g, while its own power draw stays below 0.6 W. Connecting to The Pill requires the separate 5-Terminal Add-on adapter. This card is in draft status and is currently out of stock at CasaSmart in Chisinau.
