PQM-T20-C-A

PQM-T20-C-A is a PROFIBUS DP protocol fieldbus redundant link module.The following is a detailed introduction to the product:

1.Product Overview

PQM-T20-C-A is provided by many automation equipment companies(such as Xiamen Haitong Huaye Technology Co.,Ltd.,Ruichang Mingsheng Automation Equipment Co.,Ltd.,etc.),and is a redundant link module designed for industrial automation.It can realize the mutual conversion between single bus and redundant dual bus,and can convert single cable bus to redundant Profibus DP bus,or convert redundant Profibus DP bus to single cable bus.

PQM-T20-C-A

2.Main functions and features

Redundant link conversion:

Supports the mutual conversion between single bus and redundant dual bus to improve the reliability and stability of the system.

Rate adaptation:

Dip switch setting rate or rate adaptation is optional,supporting 10 common rates of Profibus DP bus.

Industrial-grade design:

Adapt to a wide range of field environments,with IP30 protection level and corrugated aluminum reinforced housing.

Easy installation:

Adopt 35mm DIN rail installation,which is convenient for installation and disassembly in the control cabinet.

Wide power input:

Supports DC(9-36)V wide power input to adapt to different power supply environments.

Alarm output:

With relay alarm output function,it can send out alarm signals in time when the module fails.

Dual power redundancy:

Provides dual power redundancy design to ensure that the system can still operate normally when a single power supply fails.

Optical coupler isolation:

With optical coupler isolation performance,it reduces interference and improves signal stability and reliability.

III.Application field

PQM-T20-C-A

PQM-T20-C-A is widely used in industrial automation fields,such as manufacturing,power system,transportation system,etc.It is particularly suitable for control systems that require high reliability and stability,such as distributed control systems(DCS),programmable logic controller(PLC)systems,etc.In these systems,PQM-T20-C-A can provide stable data communication and redundant link support to ensure the normal operation of the system and the integrity of the data.
