This two channel RF Remote Control Relay Board is an improved
version of our original CK1617 unit. It still uses an auto roll algorithm which makes it almost impossible to steal the code for unauthorized use.
It has 2 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 15 transmitters. This unit makes
remote control very affordable for you next project.
Specifications:
- Range is over 250 feet.
- Transmits on 433.9 MHz
- Transmitter includes battery.
- Receiver Power 12 VDC (power supply not included)
(Need a Power Supply?)
- Circuit draws 9mA in idle state, 1 relay energized 40mA and
2 relays energized draws 70mA.
- 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.
- PCB Board Amperage Rating: 2 Amps Max (Even though the relay contacts
rated below can handle more amperage, the traces on the PCB can't. You
will have to beef up the traces on the board with jumper wire if you want to
switch devices that draw more than 2 amps.)
- Relay Contact Ratings: 24VDC@15A, 250VAC@12A, 120VAC@15A.
