FlexISO-S CAN isolating adapter for galvanic decoupling | STAR ELECTRONICS


Isolation separation adapter for CAN and CAN FD

Article number: 70010757

The FlexISO-S CAN isolating adapter is used for galvanic decoupling of CAN or CAN FD bus systems with a very low signal delay. As a result, the achievable line lengths are only slightly reduced. The adapter is suitable for 12 V vehicles and 24 V test bench applications.

FlexIso-S CAN.



The CAN network is separated by high-speed optocouplers. To operate the module, a power supply of 9 - 36 V is only required on the primary side. The plug-on adapter is extremely fast with a signal delay of 75 ns and ensures the recessive state of the bus level through the integrated logic. The high reaction speed ensures baud rates according to ISO 11898, up to 1 MBit/s for standard vehicle CAN and 8 MBit/s for CAN-FD. The vehicle measurement technology, PC hardware and diagnostic devices are thus reliably protected against short circuits and other errors through the decoupling.
