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.
