Terminator T1 Pepper

Product description:

The T1-Pepper provides customizable (active) termination for PROFIBUS segments that do not comply with the standard RS 485 impedance. With rotary switches the impedance of the termination can be set.

Applications

• PROFIBUS communication over non-standard cable.
• Idle voltage increaser for EMC sensitive applications.
• Impedance tuner for poor segments.

2 Rotary switches manipulate the values of the termination network. One for the middle resistor and one for the 2 pull-up resistors. The combination of both set the impedance and the level of the idle voltage. The T1-Pepper is a partner product for the COMbricks SALT repeater that requires termination at the other side of the cable. The rotary switches have to be set identical at both sides.

The T1-Pepper can be used by all fieldbuses that require active termination. It has a redundant power supply and diagnostic LEDs to indicate the status of each power source. It can be installed on a standard DIN-rail.
