The Relay Click Board™ 3 is a dual relay Click Board™, featuring two single-pole double-throw relays which can be operated by output pins of the host microcontroller (MCU). It offers an elegant and easy solution for controlling a wide range of power applications. Two SRD-5VDC-SL-C relays used on this Click Board™ are hermetically sealed relays which require 5V across their coils while consuming about 0.4W while active. They allow up to 28VDC across the connected load, while conducting up to 7A.
Relay 3 Click Board™ can be used in various PLC-based systems, as a remote ON/OFF switch, and other similar applications.
