What is the differences between relay output and DC/AC output? Carymart will tell you. Relay output: In a switch where the contacts remain in one state unless actuated, the contacts can either be normally open (abbreviated "n.o." or "no") until closed by operation of the switch, or normally closed ("n.c." or "nc") and opened by the switch action. Our remote receiver can be grouped into two types according to its current output modes. They are normally open/closed switch connection or current direct output connection (Controlled device can get power from powered receiver directly). One customer sent a picture of “Normally Open/Closed Receiver Connecting to an AC Lamp” to us to ask whether it is correct or not. Unfortunately, it is a wrong wiring. Please see a red cross to the lamp wiring from the following picture. This red cross points out the wrong wiring. AC lamp should not wire to the normally open terminals of receiver because there...

Many customers have asked us such questions: Why my lights don’t work, did I wire it correctly? Here I want to share with you the differences between relay output and DC/AC power output, and then you can check whether you have wired you lights correctly. Look at this picture, Model: 0020504 (S1U-DC12-ANT2 & CB-2L) , the receiver is relay output, not DC/AC power output, the connection is definitely wrong; the lights didn’t connect any power supply, so it can’t work. Usually, when the receiver is relay output, the wiring operation should be as follow: Connect DC power to terminal “+” and “-“. Initial state of relay output terminals: Terminals B and C are Normally Open; Terminals A and B are Normally Closed. Terminal B and C should also connect a DC/AC power supply to make the lights work. Here is the circuit diagram.   This is the correct connection. Model: 0020424 (S1X-DC06/09/12/24 & C-2) is DC power output, the wiring is easier co...

One of our customer said that he’d like to activate a hot water circulating pump in the upstairs bathroom from his kitchen which required a momentary start signal. The pump had its own power from 110/120V AC and timed operation. We recommend 1 Channel DC RF Momentary Remote Control Switch (S1M-DC12 & C-1) to him. The receiver is relay output (normally open and normally closed). Power supply for the receiver and the water pump are different. That means it will not cause electromagnetic interference during water pump operation. Simple wiring image is as follow: Press and hold the remote button, he can activate the hot water circulating pump. Online shop:  http://www.carymart.com/
