描述

Grove 2 路 SPDT 繼電器模組 單軸雙切繼電器 Grove – 2-Channel SPDT Relay

Grove 2 路 SPDT 繼電器模組 有兩個單刀雙擲(SPDT)開關。它只需要低電壓和低電流信號。控制那些開關。具體來說,您可以使用5V DC來控制最大250V AC或110V DC。最好的是你可以分別控制兩個通道。例如,由SIG1控制,您可以根據需要將COM1連接到NC1或NO1。它非常方便可靠,可以應用於需要切換高壓/高電流設備的大型產品或項目。

Grove – 2-Channel SPDT Relay

The Grove – 2-Channel SPDT Relay has two single pole – double throw (SPDT) switches. It only requires low-voltage and low current signals to control those switches. Specifically, you can use 5V DC to control max.250V AC or 110V DC.

The best thing is that you can control the two channels separately. For instance, controlled by SIG1, you can connect the COM1 to NC1 or N01 as your wish. It is so convenient and reliable that it can be applied to massive products or projects which need to switch high voltage/high current devices.

Hardware Overview

Pin Map

Grove 2 路 SPDT 繼電器模組

Schematic

K1 is the Relay module, there is a coil between pin1 and pin3 of K1. Defaultly, the COM1 will connect to NC1.If the pin3 of K1 connected to the grand, then this coil will be ‘closed’, so the COM1 will connect to NO1.

To open this coil, it requires about 90mA, however, normally the GPIO pin of Arduino only can afford 20mA(40mA max.). Therefor, we use a NPN transistors S9013 which can proviede 500mA.

The SIG1 is pulled down by the 10k R2, if there is no signal, the ‘Gate’ of Q1 will be 0v, and Q1 is turned off, so that the K1 will be ‘opened’. If SIG1 becomes 5v, then the Q1 will be turned on. Pin3 of k1 will be connected to the GND of the system, for the K1 there will be 5V between pin3 and pin1, so the coil will be ‘closed’, and the COM1 will connect to NO1

Tip

The D3 is a flyback diode(kickback diode). A flyback diode is a diode connected across an inductor used to eliminate flyback, which is the sudden voltage spike seen across an inductive load when its supply current is suddenly reduced or interrupted. It is used in circuits in which inductive loads are controlled by switches, and in switching power supplies and inverters.
