Convert Relay Voltage Free Contact / Dry Contact to Power Output Contact

Since our wireless relay receiver SR-RCS-202U and SR-RCS-201U are all voltage free contact / dry contact relays, so they don’t output voltage or power at all, sometimes customer needs to use our relay to output power to their target circuit, here we explains how to convert default voltage free contact / dry contact to terminal with power, using a simple wire connection conversion technique, as shown in photo below.


After finished connection, you can easily use the same battery or power source to power both your original target circuit and our wireless receiver.

Despite the simplicity, you will need to pay attention to power rating or polarity of both your target and our receiver, to make sure the power source doesn’t damage component during running.
