How DC/AC output different from relay output

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 is no current through them which are only equivalent to a switch.

The correct wiring is as follow. This is the 1 channel normally open/ closed ac receiver (S1U-AC220) wiring. AC lamp is connected to normally open terminals B&C. And add a wire between terminals B&N and another wire to terminals C&L. At last, wire a plug to terminals L&N. Then, we finish the wiring.

Another customer attempted to install the unit model: 0020483 (S1DA-AC220-ANT2 & CB-2) to time his water heater pump. Everything on the remote unit seems to work OK except that he cannot get voltage from the unit to the pump to make it run.
He installed the wires as follows:
From house/wall AC 120v power black (line) on L, white (neutral) on N.
TO the pump, Black (line) on B, and white (neutral) on C. Timer works fine, however with timer LED light on he get no voltage from A, B, or C. He has checked the terminals with a multi meter and there is no voltage out to the pump. Also he checked the continuity of the cord to the pump--it is OK.
Then why did water heater pump don’t work?
The answer is he didn’t wire the water heat pump correctly.
The receiver he bought is relay output, not AC power output. So the wiring is incorrect. He should also connect black (line) of AC 120v power to terminal C, connect terminal B to Black (line) of the pump, and connect white (neutral) of AC 120v power to white (neutral) of the pump.
Look at this picture, Model: 0020504 (S1U-DC12-ANT2 & CB-2L) , the receiver is relay output, not DC/AC output, the connection is definitely wrong; the lamps didn’t connect any power supply, so it can’t work.

Here is the circuit diagram.
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 lamp work.

This is the correct connection.

Model: 0020424 (S1X-DC06/09/12/24 & C-2) is DC power output, the wiring is easier compare to model:0020504 (S1U-DC12-ANT2 & CB-2L) , which is relay output
When choosing the DC power output unit, you just need to connect DC power to terminals “+” and “-”, and connect lamp to terminals “A” and “B”.
Here is the circuit diagram:

Generally speaking, the wiring differences between relay output and DC/AC output is that you should also connect a power supply to Normally Open terminal when your receiver is relay output model.

Short Description of Toggle / Momentary / Latched Working Modes

Generally there are three working modes for rf remote controls: toggle, momentary, latched. Toggle mode is used most often. Controlling lamp, for example, press the button of remote, turn on the lamp; press the button again, turn off the lamp. Momentary mode can be set to control rolling blind or rolling door. Press and hold the button of remote, open the blind or door; release the button, close the blind or door. Both toggle and momentary mode are motivated by single relay, which means you can work these two modes with single button remote. As regards the latched mode, it is motivated by relay group. For relay group, only one relay will be on at a time, e.g. press remote button A, relay A will be on, and relay B will be off; press remote button B, relay B will be on, and relay A will be off. To be more specific, when you control the lamp by latched mode, you should prepare at least two buttons remote. Press button A, the lamp is on; press button B, the lamp is off. Online s...

Remote Control Electromagnetic Lock

Image
Electromagnetic lock is a locking device that consists of an electromagnet and an armature plate. The principle behind an electromagnetic lock is the use of electromagnetism to lock a door when energized. Essentially it consists of an electromagnet attracting a conductor with a force large enough to prevent the door from being opened. That is to say, if only we could cut off power supply and make electromagnet force between electromagnet and armature plate to disappear, the door would be opened. Furthermore, we just try to use a direct dc output momentary remote and one button transmitter to cut off electric power to open the door. The following demonstration will show. At first, we prepare material. The wiring When we supply power to electromagnetic lock, electromagnet will attract armature plate through magnetic force. The door is locked. When we press button, the power supply will be cut off. The door is open as soon as electromagnetic lock unlock instantly. What’s more, t...

AC Lamp is Controlled by Customized Delay Time RF Remote Controller

Image
We recommend 1channel 110V~220V customized delay time controller (S1RD-AC220+C-2). At first, it must be set delay time in advance. According to your own actual requirement, you can set delay time you want. e. g. delay time: 20 seconds. You cannot change delay time once it is set. It is applied for controlling lights, motors, fans, electrically operated door/ lock/windows/ blinds/ cars or other appliances with AC 110~240V or DC 0~28V. You can turn on/off device on the receiver with transmitter from any place within reliable distance (theoretical distance 100m), the wireless RF signal can pass through wall, floors, doors and other obstacles. Wiring: Initial state: B, C = Normally Open; A, B = Normally Closed. AC lamp is wired to normally open terminals B&C. And add additional ac power to AC lamp. The delay time is set in advance. It is non-adjustable.   Press button 1: Turn on the relay (connect B and C, disconnect A and B) After ...
