VI.Application Scenario

A-B 1746-NI16I analog input module is mainly used to connect analog process variables to measure their amplitude,and is often used for monitoring or as a feedback signal for closed-loop control systems.It can achieve manual or automatic control by using the usual proportional integral derivative(PID)algorithm control method.Without this feedback signal,automatic control cannot be fully achieved.

The company mainly imports PLC modules,programmable controllers,servo control systems and DCS spare parts,such as:ABB,AB(Rockwell),GE(General Electric),Bentley,Honeywell Er),Emerson.),Motorola,Invensys,Westinghouse,etc.The company has established close cooperative relations with many world-renowned PLC and DCS product maintenance service providers.We can purchase goods directly from abroad and provide equipment and spare parts from different countries and manufacturers.
