Anybus T1 Terminator

Anybus T1 Terminator provides active termination for RS 485-based PROFIBUS segments. It helps manage and reduce termination errors in PROFIBUS DP networks. The 390/220/390 Ohm termination is compatible with all transmission speeds, from 9.6 kbps to 12 Mbps.

The device has a screw terminal for connection to the PROFIBUS DP segment. An additional DB9 port allows signal measurement with diagnostic tools such as ProfiTrace. The two power inputs have dedicated status LEDs: if one power supply fails, the other takes over automatically and without delay.

Why use it

T1 Terminator is ideal for:

• reducing failures caused by termination errors;
• ensuring correct termination at all baud rates;
• keeping the termination active even if one power supply is lost;
• checking power supply status at a glance;
• connecting diagnostic tools for signal measurement;
• increasing the reliability of PROFIBUS DP segments.
