Active termination resistor


Active termination resistor for PROFIBUS and RS-485 networks.

PROFIBUS and RS-485 networks can now be actively terminated easily using the PSI-TERMINATOR-PB-TBUS termination resistor. The device relies on permanent termination to ensure interference-free communication, particularly in applications that involve alternating bus devices. This prevents an open cable end through which reflections overlap the telegrams. When several devices are installed in combination, the supply voltage is easily routed through the DIN rail connector.

The PSI-TERMINATOR-PB-TBUS active termination resistor is available with ATEX and UL approvals. Thanks to the UL approval, the device can also be used on the US market without restrictions. The ATEX approval allows the device to be used in Ex Zone 2.
