Detailed Product Description

When a fieldbus is intruded by high voltage (110VAC/220VAC), CPD makes sure

1) to  protect  communication  facilities  AUTOMATICALLY

2) to  never  intefere  communication  line

3) to  prolong  service  life  of  the  facilities

4) to  record  and  alarm  immediately

CPD completely conforms to international standard ( IEC61000-4-5,IEC60939-1-2 )

Characteristics  of  CPD:

1) automatically stop facilities from being damaged by intrution of high voltage and resume the normal operation of comminication 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 lightning-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 operation of communication system

After making best use of CPD, you can

1)     enjoy the safety of your communication devices in case that they encounter the dangerous invader ( 110VAC/220VAC )

2)     ensure smooth operation of communication system

3)     easily pinpoint the troubles existing in wiring  of communication bus

4)     spare your facilities from direct lightning hit or impact of inductive lightning surfing

5)     obtain the timely alarm
