The USBRLY16-B provides eight volt free contact relay outputs with a current rating of up to 16Amp each. The processor is powered and instructed from any standard USB bus and the relay power is obtained by the DC power input adaptor.
$70
This Devantech USB relay board provides 8 voltage-free contact latching relay outputs with a current rating of up to 16A each. Controlled and powered from any standard USB bus, no separate power supply is needed. Latching relays stay in their last position when power is removed.
$61
This Devantech USB relay board provides 6 voltage-free contact relay outputs with a current rating of up to 16A each. Powered and controlled from any standard USB bus.
$56
This Devantech 8-channel USB relay module is both powered and controlled by a standard USB bus hub. It uses relays with premium ultra-low power 50mW coil types, which means that the board’s consumption of current is less than 100mA, even with all the relays on, for excellent energy efficiency.
$51
The ETH002 Ethernet relay board has 2 voltage-free contact SPCO relay outputs with a current rating of up to 16A each, all controlled over TCP/IP via Ethernet. It’s powered via a 12VDC supply, which can be either regulated or unrelated, and the 2.1mm DC input jack has a positive core polarity.
