2.Functional characteristics

PROFIBUS DP protocol support:PQM-T20-C-A is a PROFIBUS DP protocol fieldbus redundant link module that can realize the mutual conversion between single bus and redundant dual bus.It can convert a single cable bus to a redundant Profibus DP bus,and it can also convert a redundant Profibus DP bus to a single cable bus.

Rate setting:The device supports setting the rate through the dip switch or selecting the rate adaptive mode to adapt to different communication needs.

Supports common rates of Profibus DP bus:PQM-T20-C-A can support 10 common rates of Profibus DP bus,ensuring wide compatibility and flexibility.

Industrial-grade design and protection level:The device adopts industrial-grade design,has IP30 protection level,and can adapt to a wide range of field environments.Its corrugated aluminum reinforced housing and 35mm DIN rail installation method further enhance the reliability and durability of the device.

Power supply and alarm output:PQM-T20-C-A supports DC(9-36)V wide power input and has relay alarm output function,which can promptly issue an alarm signal when the device fails.

Dual power supply redundancy and isolation protection:The device also has the advantages of dual power supply redundancy and isolation protection,which further improves the stability and safety of the device.

III.Application scenarios

PQM-T20-C-A is widely used in the field of industrial automation,especially in scenarios where fieldbus redundant links need to be implemented.It can be placed directly behind the Profibus DP master station to convert a single cable bus into a redundant bus;it can also be placed in the slave station to convert a redundant bus into a non-redundant cable.At the same time,its optical coupling isolation performance can reduce interference and ensure the stability and reliability of communication.
