USB-RLY02 - 2 relay outputs at 16A.
The USB-RLY02 provides two volt free contact relay outputs with a current rating of up to 16Amp each. The USB-RLY02 is powered and instructed from any standard USB bus and does not require any additional power. The relays are SPCO (Single Pole Change Over) types. The normally open, normally closed and common pins are all available on the screw terminals.
Operating Temperature
-40C to +70C
-40C to +70C
LED indicationThe USB-RLY02 provides a red LED mounted immediately next to each relay to indicate whether it is in a powered state (LED on).
Relay power rating
If the contact load voltage and current of the relay are in the region below the solid line in the figure below, the relay can perform stable switching operation. If the relay is used at a voltage or current exceeding this region, the life of the contacts may be significantly shortened.
