Creasol UniRec2: multi-frequency receiver with 2 relay channels

This multi-frequency universal receiver has 2 relay outputs, with 250V and 5A capability, and can be supplied from 9Vdc to 36Vdc, and from 10Vac to 27Vac.

 

The fCreasol UniRec2 universal multifrequency receiver, 433 868 315 MHzcreUniRec2_300requency can be set easily using the Prog button, as like as the relay output that can be configured, indipendently for each channel, to hold-to-run, bistable, bistable ON/OFF (1 button to turn output ON, and another button to turn it OFF), and timer from 0.5s to 60 minutes.

It uses a high performance 32bit microcontroller supporting up to 1000 different remote controls in the same receiver, both fixed and rolling code, AM and FM: the maximum number depends by the code length, for example it supports up to 600 KeeLoq codes.

Programmed remote controls and configuration can be saved in a standard eeprom memory (check that it works at 3V!), so it's possible to save or restore configuration directly from the receiver.

Also, it can receive in one or two different frequencies, even with different modulation.

  • control an electronic board with two pushbutton inputs, or two electronic boards with one pushbutton input/each.
  • activate a motor up/down, for example a roller shutter motor (for this function, set for both outputs the  parameter 7 to 4, to prevent motor coils to be supplied simultaneously).
  • activate an async motor or pump
  • activate one or more lights

Using your existing remote control, it's possible for example to:

  1. open your garage door or gate, using the existing electronic board and receiver, but adding support to new remote controls;
  2. activate / disable the garden lights by using one channel of Creasol UniRec2 receiver in timer mode;
  3. activate / disable the sink pump using the second channel of Creasol UniRec2 receiver in timer mode;
  4. open your entrance door or pedestrian gate, but in this case it's recommended to use the more compact and easy Creasol UniLock device.

The product is made in Europe, provided in a nice transparent resealable recyclable clamshell, with instructions printed in several languages.

Features

  • Can be supplied  from 9 to 36Vdc and from 10 to 27Vac.

  • Frequency selected by the user: 433.42, 433.92, 434.15, 434.42, 868.3, 868.5, 868.8, 315*, 288*, 300*, 303*, 306*, 310*, 318*, 330*, 390*, 403.55*, 418* MHz. Frequencies marked with * cannot be used inside EU. The frequency of the remote control must be stable, so it does not work with remote controls without crystal or saw resonator (some bad remote controls operating around 300 MHz)!

  • OOK (AM) and FSK (FM) modulation is supported: FM with 2 different deviation value, 12 and 24 KHz; AM with standard and narrow bandwidth (higher sensitivity)

  • Twin frequency receiver: the user can select one or two frequencies/modulations as preferred, so it can receive, for example, at one single frequency or both 433 MHz OOK and 868 MHz FSK, or both 868MHz OOK and 315MHz OOK, or any combination of frequencies and modulations.

  • Works with a wide range of remote controls which transmit fixed or rolling code. See the compatibility table.

  • Manages different types of remote controls in the same time.

  • It's possible to learn one or more "master remote controls" that can be use just to enable learning for 10s without the need to access the receiver to press the Prog button.

  • High voltage and current contact rating: relay outputs support up to 250Vac and 5A (1kVA), using resistive load. Relay contacts are protected from overvoltage.

  • Wide output configurations: hold-to-run, bistable, bistable ON/OFF (1 remote control button to activate output, another button to disable output), timer from 500ms to 60 minutes.

  • Optional memory: it's possible to install a cheap optional non-volatile memory to get the programmed remote controls and configuration saved into the external memory: by default the receiver will use the configuration in the external memory, and it's possible to copy external memory to internal and viceversa using parameter 10 (please check the configuration table).

  • 2 relays with 250V 5A switching capacity, supporting up to 2kW non-inductive load per channel

Optional memory chip

The optional memory chip is a standard 24C32 memory, DIP8 package and working at 3.3V, that can be read and written using standard EEPROM programmers.

If not available, the receiver will use the memory inside the microcontroller; alternatively, if the memory is plugged in the socket, the memory inside the microcontroller will be ignored, and the optional memory will be used to store the outputs configuration and the stored radio control codes.

The optional memory can be used to:

  1. store the configuration into a removable memory, for backup purpose (using the EEPROM programmer)
  2. save a copy of the configuration, stored in the internal memory (inside the microcontroller), to the optional memory: to do this you have to push Prog button 10 times, wait for led flashing 10 times, then push Prog button 5 times. This feature is used to have a backup of the receiver configuration in a memory (that will be used in the future to program another receiver), or to copy the configuration to another receiver (see next step).
  3. copy the configuration stored in the optional memory to the internal memory (inside the microcontroller): to do this, you have to push Prog button 10 times, wait for led flashing 10 times, then push Prog button 6 times. Then you can turn OFF the receiver power supply, remove the optional memory and turn ON the receiver having the same configuration of the optional memory.

For big automations with several receivers, it can be useful to save a copy of the configuration on a memory, that will be removed from the receiver and kept by the installer, so in case of problem it's possible to recover the full configuration on another receiver to replace the old one.

UniRec2 used to turn On/Off two lights

The following diagram shows how to use UniRec2 receiver to manage two lights.
Each channel can be configured in hold-to-run (output On while remote control button is pushed), bistable (toggle On/Off), bistable On/Off (one button for On, another button for Off) or timer from 0.5 seconds to 60 minutes (configurable).

As relay output capability is 5A 250V, it can manage up to 2kW non-inductive loads.
Using inductive loads (motors or coils), relay capability is lower (depending by the inductance of the load).

Relays are protected by varistors, to suppress overvoltages during switch-off.
