“I need to operate 3 or 4 devices separately with 2 momentary functions per each. I need one transmitter to function from approx. 100 – 500m – to work all devices. The devices will operate on a 12volt DC system.”
Answer:
We recommend the 2 channel 2000m wireless momentary receiver (S2M-DC12-ANT2) with external antenna, and the long rang transmitter (CB-2). It can control lights, motors, fans, electrically operated doors/locks/windows/blinds/cars or other appliances with AC110~240V or DC0~28V. You can turn on/off the receiver with transmitter (remote control) from any place within a reliable distance; the wireless RF signal can pass through walls, floors and doors. It is momentary mode (Press and hold→On; Release→Off). External Extended antenna, its transmitting can reach about 2000m.
You can wire 4 devices to each relay of two receivers respectively. Two receivers and this transmitter will be set the same code. This receiver is NO/NC contact. Wire device to B terminals to each relay. And supply power to receiver your device respectively.
1) Press and hold big button: Turn on relays on the first receiver (connect B and C, disconnect A and B)
2) Release big button: Turn off relays on the first receiver (disconnect B and C, connect A and B)
3) Press and small button: Turn on relays on the second receiver (connect B and C, disconnect A and B)
4) Release small button: Turn off relays on the second receiver (disconnect B and C, connect A and B)
