Relay board 4-channel 5V - optocoupled

Relay board 4-channel 5V - optocoupled

Product information:

Easily control 4 relays from a microcontroller (Arduino) with 5V.
With LEDs indicating the status of the relays.
Equipped with optocouplers, which electrically separate your microcontroller from the relay.
With convenient screw terminals for connecting the device to be switched.
Each relay has a normally open and a normally closed contact.
A jumper is provided to allow the relay to be switched with Vcc.
When IN1/IN2 is made low the relay will switch.

Drive current: 15-20mA
Switching of alternating current (max. 230V) and direct current (max. 30V) up to 10A.
Dimensions: 7.2x5.1x2.0cm
