Long Range 500m Transmitter Triggered by 12V 24V DC Power ON OFF (Model: 0023005)

Package Include:
1 x Transmitter: CK-DC
1 x User manual

Working Principle:
Transmitter CK-DC is a special remote control that is triggered by 12~24V DC Power ON and OFF conditions. It has 2 input wires for connecting devices with DC voltage 12V~24V signal output, such as solar controllers, sockets, alarm hosts, detectors, sensors, programmable logic controllers (PLC), etc.
When a DC voltage of 12V~24V is supplied to the two input wires of the transmitter CK-DC, the transmitter will transmit a wireless signal "ON". 
When the two input wires of the transmitter CK-DC stop getting DC voltage of 12V~24V, the transmitter will transmit a wireless signal "OFF".

Application:
You can use this transmitter and receiver to long range remote control the AC or DC devices by the DC voltage signal of another device.

Feature:
Wireless control, easy to install.
Triggered by 12~24V DC Power ON / OFF.
Wireless RF signal can pass through walls, floors, doors or windows.
Reliable control: The signal has thousands of different combinations, and the receiver only works with the transmitter which use the same code.
Waterproof: The transmitter has waterproof case and waterproof connector, it can be installed outdoors.
One/several transmitters can control one/several receivers simultaneously.
You can use two or more units in the same place.

Transmitter Parameters:
Model: CK-DC
With 2 input wires.
No batteries are required for operation.
Triggered by 12~24V DC voltage signal.
Triggering method: When the input wires get the DC voltage signal, after 1 second, the signal LED on the transmitter flashes slowly once and then flashes quickly, the transmitter sends a wireless signal "ON". After the transmission is completed, the signal LED keeps flashing slowly. When the input wires lose the DC voltage signal, the transmitter immediately sends a wireless signal "OFF". After the transmission is completed, the signal LED flashes slowly for 30 seconds and then goes out.
Signal Transmission Time: 1 second
Operating Frequency: 433.92MHz
Transmission Distance: 500m / 1500ft (theoretically)
Case size: 110 x 86 x 40 mm

Working Range:
With a receiver to form a complete set, the maximum working distance may reach 1500 feet or 500 meters in an open area.
The maximum working distance is based on theoretical data without obstacles and any RF interference. In practice, it will be hindered by trees, walls, or other construction, and will be interfered with by other wireless signals. Therefore, the actual working distance may not reach this maximum distance.

Wiring:
1. Connect device with 12~24V DC voltage signal output to the two input wires of the transmitter CK-DC.
2. Connect the AC/DC power supply to the input terminals of the receiver.
3. Connect the controlled device to the output terminals of the receiver.

Operation:
When a DC voltage of 12V~24V is supplied to the two input wires of the transmitter CK-DC, the transmitter will transmit a wireless signal "ON". When the receiver receives this signal, thereby turning on the device connected to the receiver.
When the two input wires of the transmitter CK-DC stop getting DC voltage of 12V~24V, the transmitter will transmit a wireless signal "OFF". When the receiver receives this signal, thereby turning off the device connected to the receiver.
