0~28V or 110V~240V Device is Remote Controlled by 8 Transmitters and One Receiver

Question from customer:
I want to install a set of wireless remote controls, include 8 transmitters in 8 different places (max. 500 m) and one receiver in a specific location. The transmitter transmits a wireless signal to control a closed contact.
Answer:
We recommend normally open/closed contact toggle remote control (S1T-DC12-ANT2+CB-1). According to your requirement, you can choose 8 transmitters (CB-1) to work with the receiver. There are normally open/closed contacts in it which are able to connect device activated by DC 0~28V or AC110~240V. With external extended antenna, its working distance has reached 2000M in the open field. You can use 8 transmitters to remote control receiver from different directions.

This kind of remote control is activated by DC12 power supply. Toggle Mode is the only working mode of it. Here is the wiring diagram. Initial state: A, B = Normally Closed; B, C = Normally Open. Wire your device to normally closed contact A&B terminals. If you do this, your device is turned on always, that is to say, your device will on work all the time.

When you press button on the transmitter (connect B and C, disconnect A and B), turn off device; When you press button again (disconnect B and C, connect A and B), turn on device.
