General features

Module MREL-2s is a component of the Ampio Smart Home system. It has two independent relay outputs.

On the front of the module there are LED indicators. Green LED indicates communication over CAN-Bus:

• one regular flash every second – CAN-Bus communication in order.
• two regular flashes every second – the module is not receiving information from other modules.
• three regular flashes every second – the module cannot send information to CAN-Bus.

The module is controlled via CAN bus. Its power supply requires 11-16V DC.

Two device outputs enable independent control of eight receivers. Each output is an independent relay contact, so it is possible to connect them in such a way that one section controls 230V AC voltage, and the other one 12V DC, etc.

Typical application

  • lighting control
  • controlling propulsion machinery and any other devices with a maximum voltage of 230V AC and energy consumption not exceeding 6A.


The module can be programmed with the Ampio System Configurator available to authorised technicians. This software allows for setting up the module’s response to input signals and other information from the CAN bus.
