(Fully Assembled)

HD4COMBO


(click picture to enlarge)


This assembled four channel RF Remote Control Relay Board is an improved version of our original CK1616 unit and is similar to our HD2RX but with 2 additional channels.  It uses an auto roll algorithm which makes it almost impossible to steal the code for unauthorized use.  It has 4 relays (channels) that are individually jumper selectable as either latching or momentary.  Each channel has a reset connection, so you could use a limit switch to reset the relay if you desired.  Each channel has led indicators.  Receiver can support up to 6 transmitters.  This unit makes remote control very affordable for you next project.  

Specifications:

  • Range is up to 250 feet.
  • Transmits on 433.9 MHz
  • Transmitter includes battery.
  • Receiver Power 12 VDC (power supply not included)
    (Need a Power Supply?)
  • Circuit draws 10mA in idle state and 4 relays energized draws 120mA.
  • Relays have a Common, Normally Closed (NC), and Normally Open (NO).
  • Each relay has a reset wiring option for use to reset the relay with a limit switch.  (i.e. Garage Door Opener, set relay to latching mode, relay is energized powering door motor, door trips a travel limit switch that is wired back to the relay board turning the relay off.)
  • Each Individual Relay is jumper selectable latching or momentary. 
  • Up to 6 transmitters per receiver board.
  • Relay Contact Ratings: 24VDC@10A, 240VAC@7A, 120VAC@10A. (more info on how relays work)
