Four Transmitter and One Receiver-One to Many Series

Question from customer:
I need a unit that can receive from four transmitters, and switch 4 relays. Each transmitter controls each channel.
Answer:
We recommend the model of 4 Transmitters and 1 Receiver Kit (S4C-DC12 & 4C-1), which belongs to “One-to-many series”. “On-to-many series” include one-transmitter-to-many-receiver system and one-receiver-to-many-transmitter system. It is often used for controlling two or more electrical devices in different places by one transmitter; or one electrical device by two or more transmitters.
If you want to remote control one device with different transmitter from different places, this kit is your better choice.

Here is the wiring diagram for your reference.
The receiver is normally open & closed contact. A,B terminals are normally closed. B,C terminals are normally open. So you can wire your devices to B terminals and negative terminal of power supply. And add DC 0-28V or AC 110-240V to your devices. Supply DC 12V to receiver.

Its transmitting distance is about 100m (in the open field). You can set different working modes according to your need.
1) Setting control mode Latched: Disconnect Jumper-1 and Jumper-2.
Control mode Latched (Relay 1~4):
Press transmitter 1, light 1 ->On; other lights Off;
Press transmitter 2, light 2 ->On; other lights Off;
…
2) Setting control mode Momentary: Only connect Jumper-1.
Control mode Momentary (Relay 1~4):
Press and hold button of any transmitter-> light is on;
Release button -> light is off.

3) Setting control mode Toggle: Only connect Jumper-2.
Control mode Toggle (Relay 1~4): Press button of any transmitter -> light is on;
Press button of any transmitter again -> light is off.

4) Setting control mode Momentary + Toggle: Connect Jumper-1 and Jumper-2.
Control mode Momentary (Relay 1, 2):
Press and hold buttons of transmitter 1 or 2 -> light 1 or light 2 is on;
Release buttons of transmitter 1 or 2 -> light 1 or light 2 is off.

Control mode Toggle (Relay 3, 4):
Press buttons of transmitter 3 or 4-> light 3 or light 4 is on;
Press buttons of transmitter 3 or 4 again -> light 3 or light 4 is off.

AC 220V Output Remote Controller for Electric Shutter

Overview:
I want to buy a radio system for my 9 shutters (220 V), wireless control, 9 receivers and 1 remote, climb or descend in all my components by one remote.

Solution:
We recommend ac power output controller (S1FM-AC220), which is designed for controlling motor specially. It can remote control many kinds of motor, rolling blinds/ doors, projection screens, awnings, winches, conveyors… 10amps is its maximum current. And when it works with the long distance transmitter (CB-2), the whole kit’s transmitting distance will reach 1000m.

Connect live wire to terminal “L” and neutral wire to terminal “N”. Then connect AC motor to terminals “UP”, “COMMON” and “DOWN”. You can exchange “UP” and “DOWN” wires of motor to change rotating direction of motor. 9 shutter motors should be wired to 9 receivers respectively. 9 receivers will be programmed the same code so that they can work together with one remote.

There is only one working mode in this controller. It is inversion control mode(Press and hold big button→positive rotation; press and hold small button→reversal rotation )
Press and hold big button, terminals UP and COMMON directly output AC 220; 9 shutter motors rotate continuously in positive direction at the same time.
Release big button, stop 9 shutter motors simultaneously.
Press and hold small button, terminals DOWN and COMMON directly output AC 220; 9 shutter motors rotate continuously in reverse direction at the same time.
Release small button, stop 9 shutter motors simultaneously.

Run RC Motor Forward and Backward Wirelessly

Overview:
My plan is to be able to remotely control an RC motor forward and backward wirelessly with the remote. I was thinking one receiver and one remote, but which products would I be able to do this with.
Solution:
We recommend the model of DC power motor controller (S1FC-DC12&CV-4-2) to you. This DC RF motor remote control features in forward-reverse-stop capability. You can rotate the motor in positive or reversal direction by transmitter from any place within a reliable distance, wireless signal pass through walls, floors and doors. It is suitable for any RC motors of rolling blinds / doors, projection screens, awnings, pumps, winches, conveyors or other appliances and mechanicals. The kit’s transmitting distance is up to 500M.

Connect power wire to terminals “+” and “－”. Connect DC radio-controlled motor to terminals “UP” and “DOWN”. You can exchange “UP” and “DOWN” wires of the motor to change rotating direction of the motor.

Set Momentary control mode: Do not connect Jumper.
Press and hold button ▲ on transmitter or receiver: Terminals UP and DOWN output +DC12V (UP:+, DOWN:—), RC motor rotates continuously in positive direction.
Release button ▲ on transmitter or receiver: Stop the RC motor.
Press and hold button ▼ on transmitter or receiver: Terminals UP and DOWN output +DC12V (UP:—, DOWN:+), RC  motor rotates continuously in reverse direction.
Release button ▼ on transmitter or receiver: Stop the RC motor.
Set Latched control mode: connect Jumper.
Press button ▲ on transmitter or receiver: Terminals UP and DOWN output +DC12V (UP:+, DOWN:—), RC motor rotates continuously in positive direction.
Press button ■ on transmitter or receiver: Stop the RC motor.
Press button ▼ on transmitter or receiver: Terminals UP and DOWN output +DC12V (UP:—, DOWN:+), RC motor rotates continuously in reverse direction.
Press button ■ on transmitter or receiver: Stop the RC motor.
