This relay module can be used to switch on and off high power devices (both AC and DC).
By using a wireless module, it is possible to remotely switch On/Off a large variety of external devices.
The PC interface connection is made through the serial port.
Multiple switching functions
Interface between electronical control circuit and power circuit (potential separation)
Separation between DC and AC circuits i.e. switching of an AC circuit by a DC signal or vice versa.
Non-sensitive to short time voltage spikes or short circuits
Signal delaying, shaping and transforming
Ruggedness towards electromagnetic fields
No leakage between open contacts (galvanic separation)
