VSG1.RS485
Fieldbus unit for controlling valves
Application
The VSG1.RS485 is a field bus module for setting up distributed systems (field bus 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 thermal valves.
