This USB device features 8 solid state relays, capable to switchup to 160 VDC or 30 VAC, for small loads (up to 100 mA). It is an ideal solution to drive high-power relays. 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, and that this device should only be used with power sources protected against overvoltages (Cat. I). 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 enclosures to be ordered separately.
