This USB device features 8 solid state relays, capable to switch high voltage from the mains, for small loads (up to 100 mA). It is an ideal solution to drive high-power relays, working directly from the mains. The state of each output is shown by a LED. This device does not require any external power.
Beware that each solid state relay can only switch at most 100 mA. The terminal block is officially specified for max 160V, but the solid state relay can stand up to 400V peak. Note that even when closed, each relay keep a 25 ohms resistance. This device is mostly meant to drive large electromechanical relays, but other uses are possible.
USB cables and enclosure to be ordered separately.
