USB-RLY02-SN USB-Relais

Devantech

The USB-RLY02-SN provides two volt free contact relay outputs with a current rating of up to 16Amp each. Between the normally open and common contacts we have also integrated snubbers for inductive loads. Power for driving of the relays is conveniently sourced from the USB supply. The relays are SPCO (Single Pole Change Over) types. The normally open, normally closed and common pins are all available on the screw terminals.


Overview

USB-RLY02
Relays 2
Power Powered from standard USB bus
Control interface USB with a mini B connector
Relay current Up to 16Amp @24vdc or 250vac
Connections Screw Terminals for N/O N/C and Common contacts.


Snubbers

Integrated snubbers have be added to the module between the common and normally open poles. When inductive loads are to be used the snubbers suppress the switching spikes and relay arc associated with such loads. We have a simple guide here.


LED indication

Red LEDÂ’s are mounted immediately next to each relay to indicate whether it is in a powered state (LED on).
