Overview
Présentation de la carte Relay 4 Click Board™ , la solution compacte et robuste pour le contrôle des applications haute puissance. Cette carte complémentaire comprend le J1031C3VDC, un relais de signal unipolaire bidirectionnel (SPDT) hautement sensible et à faible consommation d'énergie de CIT Relay and Switch. Avec une conception compacte et légère, un montage sur broche PC et une disposition de contact 1C avec une tension de bobine de 3 VCC, ce relais peut gérer une tension de commutation maximale de 125 VCA/60 VCC. Mesurant seulement 12,5 x 7,5 x 10 millimètres (L x l x H), il est facile à intégrer dans n'importe quel système équipé de la prise mikroBUS™.
De plus, le développement logiciel est un jeu d'enfant grâce à la bibliothèque compatible mikroSDK incluse et à la conception pré-testée. Mettez à niveau votre système avec le Relay 4 Click Board™ dès aujourd'hui !

How Does The Relay 4 Click Board™ Work?
The Relay 4 Click Board™ is based on dual J1031C3VDC, high-current single-pole double-throw (SPDT) signal relays from CIT Relay and Switch. The J1031C3VDC relay is well known for its reliability and durability, high sensitivity, and low coil power consumption housed in a small package with PC pin mounting. Despite its size (12.5x7.5x10 millimetre (LxWxH)), the J1031C3VDC relay can withstand up to 2A and 125VAC/60VDC maximum. These relays are designed to easily activate their coils by relatively low currents and voltages, making them a perfect choice that any MCU can control.
As mentioned, the contact configuration of the J1031C3VDC is a single-pole double-throw (SPDT), which means that it has one pole and two throws. Based on the default position of the pole, one throw is considered normally open (NO) while the other is normally closed (NC), which is, in this case, its default position. When the coil is energized, it will attract the internal switching elements similar to a switch.
The Relay 4 Click Board™ uses two mikroBUS™ pins for its proper operation, the RL1 and RL2 pins routed to the RST and PWM pins of the mikroBUS™ socket. These pins control small N-channel MOSFET RET (Resistor Equipped Transistor) transistors that provide enough current for the relay coil. Two resistors are already integrated into the RET, providing it with the correct biasing and simplifying the design. Also, each relay has its own yellow LED indicator, which signalizes the state of the relay. When the current flows through the RET, the coil will be energized, and the relay will be switched from a closed to an open switch state.
The Relay 4 Click Board™ can be operated only with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before using MCUs with different logic levels. However, the Click board™ comes equipped with a library containing functions and an example code that can be used as a reference for further development.
