• Yocto-MaxiCoupler-V2

This USB device features 8 solid state relays, able to switch directly up to 48 VDC or 30 VAC r.m.s. for loads up to 1.3 A. Thanks to their on-state resistance of only 0.1 Ohm, they can even stand short peaks up to 5 A (max.100ms). This device therefore provides a compact alternative to mechanical relays for switching signals an small loads.

The state of each output is shown by a LED. This device does not require any external power. Each output is features a multilayer varistor, which protects the solid-state relay against voltage transients.

This device can be connected directly to an Ethernet network using a YoctoHub-Ethernet, to a WiFi network using a YoctoHub-Wireless-n and to a GSM network using a YoctoHub-GSM.
