Precautions for the use of SK series wireless switch module

The SK series wireless switch module is one of the main products of NiceRF Wireless, which has been widely popular in the market and has many users. Since the launch of this module, we have received a lot of feedback from customers. Among them, due to customer improper operation, the damage and repair of the wireless switch module accounted for the majority. In response to the above-mentioned problems, NiceRF Wireless hereby writes the precautions for the use of SK series modules, hoping to help everyone avoid some problems in the use process.

Relay voltage and current

The relay is an electric control device of the wireless switch module, which has the function of loading and controlling the switch, and is used for the customer to remotely control the product. The relay has a very important point to pay attention to, that is, the load voltage of the relay cannot exceed 220V and the current cannot exceed 1A, otherwise the relay will burn out.

Module power supply

The power supply of the SK series wireless switch module cannot exceed 30V for direct power supply. Power supply exceeding 30V will cause the voltage to be too high and cause the module to burn out. In the past, customers have made such mistakes.

Input signal voltage

The signal at the input end of the SK series wireless switch module cannot carry high voltage, and can only be connected to dry contacts (the contacts of the switch cannot carry electrical signals), otherwise there is a high probability that the internal IC of the module will be burned.

Antenna

The antenna must be installed when using the SK series wireless switch module, even if it is only a short-term test, the antenna must be installed. Because the SK series module cannot transmit the signal without the antenna, it is very likely to cause the chip to burn out.

The above four are the most likely to cause damage to the SK series wireless switch module. You can avoid many problems by paying more attention when using it. Finally, if you still encounter other unsolvable problems, welcome Customers come to consult us @ sales@nicerf.com.
