Price: US $44.00

Add to Cart:   

  • Model: 0020496 (S1U-AC & 2C-2L)

Please Choose:

  • Wireless control, easy to install
  • Waterproof case with waterproof connector
  • Relay output, can control Lights, Motors, Fans, electrically operated Doors/Locks/Windows/Blinds/Cars or Other Appliances with AC110-240V or DC 0~28V.
  • Universal input: support voltage of AC110V (100V~120V), widely used in US, Canada... and voltage of AC220V (200V~240V), used in UK, France...
  • 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
  • Use an 8-bit microprocessor designed and developed with low-power and high-speed CMOS technology.
  • Reliable control: The transmitter (Encoding) and the receiver (Decoding) use an 8-bit code.
  • One/several transmitters can control one/several receivers simultaneously.
  • If you use two or more units in the same place, you can set them with different codes.

Receiver Parameters:
  • Model No.: S1U-AC220
  • Power Supply (Operating Voltage): AC100~240V (110V/120V/220V/240V)
  • Working Frequency: 315MHz / 433MHz
  • Channel: 1 CH
  • Control Modes: Toggle, Momentary, Latched
  • Output: Relay output (Normally open and normally closed)
  • Working Voltage Range of Relay: AC110~240V or DC0~28V
  • Maximum Working Current of Relay: 10A
  • Static Current: ≤6mA
  • PCB size: 90mm x 59mm x 18mm
  • Case size: 100mm x 68mm x 50mm
  • Work with Fixed code transmitters or Learning code transmitters.
  • The receiver can pair different model transmitters, includes model C-1 / C-2 (100M), CWB-1 / CWB-2 (50M, waterproof), CP-1 / CP-2 (500M) and CB-1 / CB-2 (1000M) etc...
  • 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.

  • Model No.: 0021115 (C-2L)
  • With Sliding Cover: Slide up when it doesn’t work (to protect the button). Slide down the button will appear.
  • Shell Color: Wood Color/ White/ Black
  • Channel/Button: 2
  • Button Symbol:1, 2
  • Operating Voltage: 12V (1 x 23A -12V battery, can be used for 12 months)
  • Operating Current: 3mA
  • Operating Frequency: 315Mhz / 433Mhz
  • Encoding Chip: EV1527
  • Encoding Type: Learning code (up to 1 million codes, reducing code collision and unauthorized code scanning possibilities.)
  • Transmitting Distance: 100m / 300ft (theoretically) 
  • The distance of 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 exposed to some interference by other signals. Therefore, the actual distance may or may not reach 100m.
  • If you stretches the telescopic antenna, it can have a further working range, which is twice as much as it used to be.

Package Include:

  • 1 x Receiver: S1U-AC110 / S1U-AC220 (1 Channel / Three Control Modes)
  • 2 x Transmitter: C-2L
  • 1 x User manual


  • The theoretical distance is 100m, which shall be operated in an open ground; no barriers and no any interference. But in actual operation, it is hindered by trees, walls or other obstacles, or interfered by other signals. Therefore, the actual distance can not reach 100m. If you need longer range, please choose other series of remote control, such as CB Serie(1000m/3000ft) - Click here; Or you can add the External Extend Antenna (model: 0020909) on the receiver for improve the range - Click here.
