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.
