Barrier card SRC RP302

توضیحات محصول

Barrier card SRC RP302

تکرار کننده سیگنال برای پروتوکول Fieldbus برای بازه گسترده ای از تجهیزات ابزار دقیق از جمله پوزیشنرها و دیگر کاربردها است.

Compatible with IEC 61158-2, 31.25 kb/s, FOUNDATION Fieldbus H1, and Profibus PA
Allow extension of the network length beyond the 1900m Fieldbus specification.
Built-in terminators jumper selectable on both sides.
Low leakage current ( < 1 uAdc ) will not interfere with network power.
Galvanic isolation between networks will block noise-jitter propagation.
Small size and light weight enclosure for DIN mounting rail.

Technical Characteristics
* Complies with the IEC61158-2 Physical Layer definition for Fieldbus.
** Applies only to networks wired in series.
