Active termination resistor with redundant voltage supply for PROFIBUS and RS-485 bus systems.

Compact design. Electrical isolation between supply and data interface. Bus termination can be

switched. Integrated programming interface.

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.
