The Relay4 Board is small-sized board with 4 Relays (each supports currents up to 16A). Also, it contains ULN2804 (high-current Darlington arrays) for relays driving and IDC10 connector for easier connecting with development or prototype board.
Relay click 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 can be used in various PLC-based systems, as a remote ON/OFF switch, and other similar applications.
Relay click 3 is supported by a mikroSDK compliant library, which includes functions that simplify software development. This Click board™ comes as a fully tested product, ready to be used on a system equipped with the mikroBUS™ socket.
Signal Relay click can be used for ON/OFF control in various devices. It carries four ultra-small GV5-1 PCB relays from Omron and runs on a 5V power supply. Signal Relay click communicates with the target MCU over the following mikroBUS pins: AN, RST, CS and PWM.
Dual relay Click board - control a wide range of high power applications
Relay click is a dual relay Click board, which can be operated by the host MCU. This Click board™ offers an elegant and easy solution for controlling a wide range of high power applications. Since it is able to operate on mains voltage level, it can even be used control the power for a number of small home appliances. It can also be used to activate various electromotors, switch on the lights, or power on the entire embedded system.
