Remote controll receiver with a floating code.

We are pleased to introduce a high sensitivity receiver with HCS decoder embedded, the compact 4 output channels radiofrequency receiver RX-4MHCS from Aurel.

This is an archive article published 02/26/2010. Some information may no longer be up to date and in line with the current state. Please contact us in case of interest.

This module contains besides RF receiver also integrated circuit, which is used for decoding a floating code generated by HC300 IC (Microchip). For the operation an external antenna is needed to be connected and 5VDC supply voltage to be applied.

To achieve maximum performance we recommend to use 433,92 MHz external antenna for example type T433 . For remote controll of the module you can choose from several AUREL´s key-fob transmitters. Only the keyfobs with HCS encoder shall be recognised by the receiver RX-4MHCS.

If an inductive load is connected to the output (a relay) it is necessary to prevent voltage transients by putting a diode in parallel to the inductive load.

Push buttons in the keyfob are intended for making all outputs active. The receiver can be programmed for up to ten different transmitters with preprogrammed Aurel code.

Features:
  • Reception frequency: 433,92MHz
  • Supply voltage: 5V
  • Supply current: 3mA
  • Modulation: OOK (AM)
  • RF sensitivity: -106dBm
  • Number of output channels: 4
  • Open collector output: 100mA
Suitable applications:
  • Gate door openers
  • Burglar alarms
  • Lighting
  • Home automation applications
  • Wireless identification applications
