SparkFun Qwiic 4 路 AC 大電流固態繼電器套件 每路 40A IIC 通訊 直流 3V 即可觸發 可擴展至400 路 支援 Arduino 與 樹莓派
SparkFun Qwiic Quad固態繼電器套件採用了我們最喜歡的固態繼電器之一,可讓您在單個PCB上最多放置四個繼電器,以通過所需微控制器的I 2 C控制所有繼電器。每個繼電器在28-380 VAC時的額定電流為40A,因此,通過板上所有四個繼電器,您都可以通過易於使用的Qwiic Connect系統控制一些強大的電源。該套件無需焊接,但需要一些小的裝配才能將繼電器連接到板上並連接交流負載。
板上的ATTiny84已預先編程,可以接受各種命令來切換所有四個繼電器。ATTiny84的I 2 C地址是軟件可配置的,因此,如果您有需求和力量,可以菊花鏈方式連接100 個以上的Qwiic Quad繼電器(但是請注意,在3.3V總線上切換大量繼電器會導致電壓尖峰,因此需要外接電源)!此外,可以打開地址跳線以將I 2 C地址從0x08(默認)切換到0x09(備用)。
遇到如此高的電壓很危險!這是一個電源附件,面向在高交流電壓周圍有豐富經驗和知識的用戶。如果您不適應高交流電壓,也可以!請改為檢查IoT功率繼電器。物聯網功率繼電器完全封閉,使其更加安全。另外,對於小負載(例如4-10A),空氣冷卻應該足夠了,但是如果您採購的資源更多,則強烈建議使用散熱器。有關推薦的散熱器尺寸,請參見繼電器數據表。
注意:套件中不包括黑色的支架和用於固定它們的4-40螺釘,如某些照片所示。如果您想在訂單中包括一些配件,請查看下面的連接配件。

SparkFun Qwiic Quad Solid State Relay Kit
The SparkFun Qwiic Quad Solid State Relay Kit takes one of our favorite solid state relays and lets you place up to four of them on a single PCB to control all of them via I2C from your desired microcontroller. Each relay is rated to 40A @ 28-380 VAC so with all four on board you can control some serious power all from the easy-to-use Qwiic Connect System. The kit requires no soldering but there is some minor assembly required to attach the relays to the board and to connect your AC load.
The ATTiny84 on the board comes pre-programmed to accept various commands to toggle all four relays. The I2C address of the ATTiny84 is software configurable so so if you had the desire and power, you could daisy chain over 100 Qwiic Quad Relays (but please be aware that toggling lots of relays on a 3.3V bus can cause voltage spikes so an external power supply will be required)! In addition, the address jumper can be opened to switch the I2C address from 0x08 (Default) to 0x09 (Alternate).
Messing with such high voltage is dangerous! This is a power accessory intended for users who are experienced around, and knowledgeable about, high AC voltage. If you’re uncomfortable dealing with high AC voltage, that’s okay! Check out the IoT Power Relay instead. The IoT Power Relay is fully enclosed, making it a lot safer. Also, for small loads (eg. 4-10A), air cooling should be sufficient but if you are sourcing more than that, a heat sink is highly recommended. Refer to the relay datasheet for recommended heat sink dimensions.
Note: The black standoffs and 4-40 screws used to secure them shown in some of the photos are NOT included with the kit. Check out the Hookup Accessories below if you would like to include some in your order.

- I2C Address: 0x08 (Default), 0x09 (Alternate via jumper)
- Max Current (Through Relay): 40A (24-380VAC)
- Zero Cross Trigger
