Shelly The Pill SSR Add-On Dual-Channel Solid-State Relay

Shelly The Pill SSR Add-On Dual-Channel Solid-State Relay

The Shelly The Pill SSR Add-On is a compact dual-channel solid-state relay module designed to add low-voltage DC load control to The Pill by Shelly. Its two galvanically isolated outputs can independently switch compatible lights, fans, solenoids and other DC devices, supporting practical automation projects without the mechanical switching noise of a conventional relay.

Important compatibility note: This is an accessory rather than a standalone smart relay. It requires The Pill by Shelly and the Shelly 5-Terminal Add-on for connection; both products are sold separately. It is intended for compatible DC loads up to 30 V DC and 300 mA per channel.

Smart Control for Low-Voltage Projects

The SSR Add-On gives The Pill by Shelly two independently controlled, potential-free solid-state relay outputs. Once connected, compatible loads can be controlled through The Pill and incorporated into schedules, scenes or automations using the Shelly Smart Control app.

Key Features:

• Controls two independent low-voltage DC loads from The Pill by Shelly.
• Supports a maximum switching voltage of 30 V DC and current of 300 mA per channel.
• Galvanically isolated solid-state relay outputs provide electrically isolated switching without moving relay contacts.
• Suitable for compatible LED indicators, LED strips, small DC fans, motors, solenoids, valves and locking mechanisms.
• Includes one configurable 3.3 V logic-level input or output through the IO3 terminal.
• Optional 5 V and ground terminals can provide power for a connected peripheral or The Pill.
• Compact 36 × 31 × 11.5 mm enclosure is suitable for integration into low-voltage projects and equipment cabinets.

Two Independent Solid-State Relay Channels

LOAD1 and LOAD2 can control separate DC loads, allowing one compact module to manage two different functions. For example, one channel could switch a low-voltage indicator while the other controls a compatible fan or solenoid.

Practical Applications

Low-Voltage Device Control

Connect compatible LED indicators, lighting accessories, small fans or other DC loads to bring them into a Shelly automation. Each channel can be controlled according to configured schedules, scenes or supported sensor data.

Automated Valves and Locks

The relay outputs can operate compatible low-voltage solenoids used in applications such as water valves, door locks or simple mechanical latches, provided the connected load remains within the specified electrical limits.

DC Fan and Ventilation Control

A compatible low-voltage DC fan can be switched on a schedule or in response to supported sensor readings through The Pill. This can help automate airflow in small spaces, equipment cabinets and similar low-voltage installations.

Connections and Wiring

The module provides LOAD1 and LOAD2 relay outputs, a configurable IO3 connection, ground and an optional 5 V power terminal. Installation must follow Shelly’s wiring guidance and the voltage and current limits of both the module and connected equipment.
