The relay module is a separate hardware device used for remote device switching. With it you can remotely control devices over a network or the Internet. For the industrial use of the relay modules, it is important that they can easily be inserted and quickly be mounted. Devices can be remotely powered on or off with commands delivered over a local or wide area network. You can control computers, peripherals or other powered devices from across the office or across the world.
The Relay module can be used to sense external On/Off conditions and to control a 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)
Signal multiplication: low power controls high power
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
Easy handling
Ruggedness towards electromagnetic fields
No leakage between open contacts (galvanic separation)
