મહત્વપૂર્ણ: પાવર સપ્લાય વોલ્યુમની ખાતરી કરોtage matches the label on the product. Incorrect voltage can damage the module. Always disconnect power before wiring.
4.1 વાયરિંગ ડાયાગ્રામ
The W3230 controller has terminals for power input (+VCC, -GND), sensor input (S1, S2), and relay output (LOAD). Connect the power supply to +VCC and -GND. Connect the NTC sensor to S1 and S2. The load (heating or cooling device) should be connected to the relay output terminals, ensuring it is within the relay's specified current and voltage ક્ષમતા.
