Description:

1.automatically stop facilities from being damaged by intrutionof high voltage and resume the normal operation of communicationline

2.never affect the normal operation of fieldbus

3.record the numbers of the intrution of high voltage

4.over-tension protection components with characteristics oftwo-way voltage-stablizing and two -way negative resistance

5.circuit with polymer materials

6.reliable lightining-protection function

7.high voltage intrusion count

The major hazards of high voltage intrusion (110VAC/220VAC)arelisted as follows:

1)To fatally destroy communication bus modules or otherelectronic devices:terrible attack to all facilities(computers inparticular)frecuently occurs owing to the vulnerability offieldbus

2)To accelerate the aging of equipments and chips ofcommunication and shorten the life of communication chips

3)To affect normal operate of communication system
