Product description

PROFIBUS or other RS-485 networks can be actively terminated at the end of the bus using the PSI-TERMINATOR-PB. This ensures safe communication even if the bus device is connected/disconnected during operation. In addition, the connectable termination enables the device to be operated as a service interface at any point in the bus system. For the operation of active programming and diagnostic devices, the required power supply is provided at the alternative D-SUB connection.
