433 MHz 4-channel self-learning receiver – KIT

Description

Four-channel receiver with relay outputs, compatible with four-channel transmitters operating at 433.92 MHz and encoded with MM53200, UM3750, or UM86409 (12-bit encoding), allowing up to 4,096 combinations. The circuit features four independent outputs, configurable to operate in pulse (monostable) or level (latching, i.e., bistable) mode, all associated with a normally open relay, making them suitable for controlling any kind of electrically activatable load or device. The relays can switch voltages up to 60 V and currents on the order of 1 A, but it is possible to drive more demanding loads by having them handled by appropriately rated slave relays, powering their coils via the relay contacts of the circuit. Power supply: between 12 and 14 V – 200 mA.
