PLC BECKHOFF BC9191-0000 AUTOMATION ROOM CONTROLLER

The compact BC9191 room controller has an integrated PLC and the sensor/actuator interfaces necessary for room automation. This way, it can be used as an autonomous or local controller. Compared with the BC9191-0000, the BC9191-0100 has an RS485 interface so that, for example, room control units, weather stations, electric door openers or DMX slaves can be connected. Communication with the devices generally takes place via the Modbus RTU protocol, but may also take place via a serial protocol which the user can freely define. The K-bus interface makes extension by the entire range of Bus Terminals possible at any time.
