BSK-Modul

Fieldbus unit for controlling fire dampers, housing IP54

Application
 The FB4DI.2DO-R is a Fieldbus module for setting up distributed systems (Fieldbus systems) in industry, building services and HVAC. These units are arranged in a decentralised way and read and written by a central CPU (PLC, PC) via interface RS485 and Modbus®-RTU. This module is used to control fire dampers.
