2 Channel AC110V/220V Radio Memory Remote Control RF Receiver

Feature:
Application: It can be used in industry automation, agriculture automation and home automation, such as factory, house, farm, pasture, vehicle, ship, offshore operation, aerial vehicle, field call, etc. It can remote control equipments on land, water and air, such as remote control lights, sirens, locks, motors, fans, winches, blinds, linear actuators, doors, windows, electric solenoid valves, security alarm, business signs and various devices.
Wireless control, easy to install
Waterproof: The receiver has waterproof case and waterproof connector, it can be installed outdoors.
Universal input: Support voltage of AC110V (100V~120V), widely used in US, Canada... and voltage of AC220V (200V~240V), used in UK, France...
Relay Output: This receiver is relay output, it can be used to operate both DC and AC equipments. The terminal is NO / NC (normally open / normally closed), which serves as a switch. That means you should also connect a separate power supply to it.
With manual terminals: The receiver allows you to connect external devices, sensors, or manual switches to control the receiver.
With the external antenna, it can have a further working range.
Use an 8-bit microprocessor designed and developed with low-power and high-speed CMOS technology. 
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. 
With characteristics of reverse power protection and over current protection.
Reliable control: The receiver only works with the transmitter which use same code.
One/several transmitters can control one/several receivers simultaneously.
You can use two or more units in the same place.
With a transmitter (such as C-2) to form a complete set, the working distance can reach 100m in an open ground. The maximum working distance 100m is a theoretical data, it shall be operated in an open ground, no barriers, no any interference. But in the practice, it will be hindered by trees, walls or other constructions, and will be interfered by other wireless signals. Therefore, the actual distance may or may not reach 100m. If you need longer range, please choose powerful transmitters, such as CB Series (1000m/3000ft); or you can add the external antenna to the receiver for improving the range.

If you want to have a further working range, you can install an external antenna to the receiver, such as magnetic mount antenna (model 0020909), which working range is three times as much as it used to be. Or telescopic antenna (model 0020918), which working range is twice as much as it used to be.

Usage (with the transmitter):
The receiver can be used to control both DC 0~28V and AC 110~240V equipments.
Notice: The receiver is relay output, not DC/AC power output. Initial state of relay output terminals: Terminals B and C are Normally Open; Terminals A and B are Normally Closed.

If you want to control a DC 12V lamp, do as following:
1) Connect the live wire of the AC power supply to terminal “L / +”, and the neutral wire of the AC power supply to terminal “N / -“.
2) Connect terminal C to the positive pole of the DC power supply, connect terminal B to the positive pole of the DC lamp, and connect the negative pole of the DC lamp to the negative pole of the DC power supply.

If you want to control an AC 220V lamp, do as following:
1) Connect the live wire of the AC power supply to terminal “L / +”, and the neutral wire of the AC power supply to terminal “N / -“.
2) Connect terminal C to the live wire of the AC power supply, connect terminal B to one side of the AC lamp, and connect another side of the AC lamp to the neutral wire of the AC power supply.

Setting different control modes (We have set the receiver as Self-locking control mode before delivery. If you want to use other control modes, do as following operation):

Function of memory:
When the relay is on the status of "ON", it will shift to the status of "OFF" when the power is cut off.
Once the power is restored, the relay will return automatically to the previous status of "ON".

Manual control terminals:
The receiver has manual control terminals, you can connect external devices, sensors, or manual switches to control the receiver.
1) Signal input:
You can connect external devices (with low level output signal) to terminals “1”, “3”, the external device’s output signal can control the receiver.
When the external device outputs low level signal to terminal “1” and “3“, turn on the relay1 (connect terminals B and C, disconnect terminals A and B).
When the external device does not output  signal to terminal “1” and “3“,  turn off the relay1 (disconnect terminals B and C, connect terminals A and B).
You can connect external devices (with low level output signal) to terminals “2”, “3”, the external device’s output signal can control the receiver.
When the external device outputs low level signal to terminal “2” and “3“, turn on the relay2 (connect terminals B and C, disconnect terminals A and B).
When the external device does not output  signal to terminal “2” and “3“,  turn off the relay2 (disconnect terminals B and C, connect terminals A and B).

2) The manual switches:
You can connect one manual switch to terminals “1”, “3”, and then you can use this manual switch to control the receiver.
When connect terminals “1” and “3”, turn on the relay1 (connect terminals B and C, disconnect terminals A and B).
And when disconnect terminals “1” and “3”, turn off the relay1 (disconnect terminals B and C, connect terminals A and B).
You can connect one manual switch to terminals “2”, “3”, and then you can use this manual switch to control the receiver.
When connect terminals “2” and “3”, turn on the relay2 (connect terminals B and C, disconnect terminals A and B).
And when disconnect terminals “2” and “3”, turn off the relay2 (disconnect terminals B and C, connect terminals A and B).
