Active termination resistor for PROFIBUS and RS-485 bus systems, redundant power supply,

routing of the supply voltage via DIN rail connector, electrical isolation, switchable termination,

integrated programming interface

Product Description

PROFIBUS or other RS-485 networks can be actively terminated at the bus end using the PSI-TERMINATOR-PB-TBUS. 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 devices, the required

power supply is provided at the alternative D-SUB connection. When several devices are installed in combination, the supply voltage can be

conveniently routed through the DIN rail connector.
