RELAYLO1 Yocto Relay


USB module with two small relays for switching up to 57V / 2A

SKU: RELAYLO1 Categories: ,


The RELAYLO1 Yocto Relay contains two USB-driven miniature unipolar relay switches. You can drive by software each relay input to one of two individual outputs (computer-driven switch). To make it easier to test your project, four leds positioned on the front side of the connector show the output currently active for each relay.

This product is designed to stand up to 55V and a current of 2A, but no more than 60W. Be aware that using a relay to drive inductive loads (motors, transformers) may lead to accelerated aging of the relay. Please refer to the documentation for hints on reducing this type of problems.

This device can be connected directly to an Ethernet network using a YoctoHub Ethernet, to a WiFi network using a YoctoHub Wireless-g, it can even be connected to a GSM network thanks to the YoctoHub GSM.

USB cables and enclosure to be ordered separately.
