WSP300
Intelligent Segment Protector for FOUNDATION™ fieldbus, PROFIBUS-PA
The WSP300 offers spur protection against short circuits (between + and – terminals), limiting the short circuit current in each spur. During a short circuit situation there is no effect in the other spur or the main trunk. There is a LED to indicate short circuits and WSP300 has an integrated bus terminator in the models F and P.
In normal operation, each short circuit protector consumes less than 3 mA. After removing the short circuit, the spur goes back to normal operation, the protection circuit is disabled and the LED is dimmed.
- Intelligent Segment Protector for fieldbus installations in compliance with the IEC61158-2 standard (PROFIBUS PA and FOUNDATION™ fieldbus);
- 4, 6 or 8 spurs;
- Intelligent protection against short circuit in each spur, preventing the short circuit propagation. After removing the short circuit, the spur goes back to normal operation;
- For panel mounting or field installation in junction boxes;
- Integral part of JB400 – Intelligent Junction Box;
- Quick and easy installation;
- Maintenance during operation.
To better serve your application, the intelligent segment protector WSP300 is available in the following models:
- F – For FOUNDATION™ fieldbus networks
- P – For PROFIBUS PA networks
