Relay modules

WB-MR are relay modules (contactors) controlled via Modbus RTU. They are used for switching various load types: lighting, ventilation, heated floors, equipment power supply units etc.

The product line includes modules with a large selection channels and load capacities. We are particularly proud of our relay modules designed for direct control of loads with high inrush current (up to 800A) eliminating the need for a separate contactor: LED lighting, incandescent lamps etc.

The majority of modules are equipped with discrete inputs that can be used for direct control of the relay channels or as general purpose inputs.

Each output is rated 10A and can withstand inrush current as high as 80A and continous load of up to 16A.

The module has a built-in power supply that allows:

  • Save space and simplify installation in small installations without a controller: no need for an external power supply and wires for it. At the same time, you will receive local control from the buttons and a reserve for future automation.
  • Ensure that the relay operates when the low-voltage RS-485 bus is disconnected or damaged — module will automatically switch to the internal power supply and continue to work in the mode specified during configuration.
  • Emulate relays with normally closed contacts, but much more current than such relays traditionally switch.

Also used as general-purpose discrete input/output module.
