Tuya Wifi Dry Contact Switch Module
Overview
The Tuya Dry Contact Switch Module wifi smart switch designed for DIY enthusiasts and home automation tinkerers. It’s particularly handy for scenarios where you need to control devices without adding current. Here are the key points:
Dry Contact vs. Wet Contact Relays:
Dry Contact: The output terminals supply no power. It has two isolated circuits—one for powering the device and another for closing the circuit connected to its output terminals. If input voltage is 220V, the output remains 0V.
Wet Contact: The output terminals supply the same source power as the device. When the switch is turned on, the output power is immediately supplied along with the input (identical voltage).
Features and Advantages
DIN Mountable Design:
The module can be easily mounted on a DIN rail, making it suitable for installation in electrical panels or enclosures.
Maximum Load of 150 Watts:
It supports a maximum load of 150 watts, allowing you to control various low-power devices such as lights, fans, or small appliances.
Momentary Mode:
The relay operates in a “momentary mode,” meaning it acts as a button without providing voltage output. This is useful for simulating button presses or triggering other devices.
Integration with Smart Home Systems:
You can link it to other smart devices within your home automation ecosystem.
Use Cases:
Automate garage doors, gate doors, windows, and smart curtains.
Simulate button presses for various scenarios.
