The way of Circuit Connection:
Please Note: the Receiver Switch Module part number KR1204-4 have 3 ways of working mode.The OUTPUT signal have 2 Voltage Level. It decided by the IMPUT of the COM pin.
OUTPUT mode 1:
Connect the COM to the Power Supply by DC12V, the Output pin will create DC12V Signal. Please check below diagram for better understanding.
OUTPUT mode 2:
Connect the COM pin with any other Additional Power Supply，the output will create the same Voltage signal as the Additional Power Supply. it can be Direct Current or Alternating Current. Decided by the Additional Power Supply.
BUT, Please note: the additional Power Supply should be in the range of the Receiver Switch Module-(DC5-12V, AC 85-240V).
Please check below diagram for better understanding.
OUTPUT mode 3:
Mix work mode: You can also make 2 channel work under the DC output mode, and 2 with the AC output. Please check below diagram for better understanding.
