Product description
This relay module provides four independent switches that can be actuated via digital signals from a microcontroller. The module operates with a voltage of 12 V, which requires an external power supply. Each channel can switch loads of up to 10 A, making it suitable for many practical applications.
The module contains four relays whose coils are energized by the control signals. The contacts can then switch external loads on or off, independently of the control voltage. An LED indicates the switching status of each channel. Because the relays provide galvanic isolation, they can also be used to switch larger circuits without a direct electronic connection.
The module is suitable for switching on pumps, solenoid valves, or heating elements in automated systems. It can be used to implement alarm or safety circuits, for example to trigger door locks or warning signals. In traffic simulations or model railway controls, points, signals, and track power circuits can be switched. Remote control of lights or small motors via relay logic is also possible.
Connections are made via terminal blocks for the control signals and screw terminals for the load circuits. A separate 12 V power supply must be provided. The maximum switching power per channel is approximately 120 W at 12 V DC; higher voltages or AC voltages require testing according to the datasheet. The module works reliably with common microcontroller boards and requires one control input per channel.
Safety notice
The module is intended exclusively for building prototypes and for testing and development purposes. It is not suitable for continuous operation in residential electrical installations. A qualified electrician must be consulted for switching tasks in or near electrical installations. In the event of a fault or when operating with unknown loads, consult a qualified electrician before commissioning.
