The termination of Profibus networks is now performed by the new active PSI-Terminator-PB-TBUS termination resistor from Phoenix Contact.
This device relies on permanent termination to ensure interference-free communication, particularly in applications that involve alternating bus devices.
The bus line can be connected either via a plug-in double spring terminal block or a D-SUB socket. Alternatively, the active programming and diagnostic devices can be supplied with voltage using the D-SUB connection. This also makes the device suitable for use as a defined service and measuring-device connection within a bus system. LED displays with bus activity and the redundant power supply are available to the user for local diagnostics.
When several devices are installed in combination, the supply voltage can be conveniently routed through the DIN rail connector. The extended temperature range from -40°C to +70°C makes it suitable for use under industrial ambient conditions. The housing saves space in the control cabinet thanks to its compact design.
