Detailed Product Description

Communication Protective Device

Detailed Product Description

1.automatically stop facilities from being damaged by intrution of high voltage and resume the normal operation of communication line

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 of two-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)are listed as follows:

1)To fatally destroy communication bus modules or other electronic devices:terrible attack to all facilities(computers in particular)frecuently occurs owing to the vulnerability of fieldbus

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

3)To affect normal operate of communication system
