BB-RELAY3-5V

Three relays with LED status indicator and Opto isolated inputs. Relay contacts N.O., COM, and N.C are on terminal block. The operating voltage of the relay coil is 5V. Can be driven with any microcontroller GPIO at 3.3V or more.

Relays require 5 DC to get powered, connect power to the VCC and RGND pins.

Control signals require above 3V DC or above (up to 5V DC) to trigger, remember to connect driving signal GND to GND pin.
