西门子流量计和变频器的应用分析

Application Analysis of Siemens Flow-Meter and Transducer

将西门子旋转活塞流量计7MR1110-1DR70-2AA0-Z和脉冲发生器7MV1150-2AA00与2个OMRON H7BR-BV计数器结合用于批量和累积量计数时,通过脉冲信号转换器7MV1070-1AC10-0AA0,其脉冲信号转换器输入端子向脉冲发生器提供8.2VDC电源,脉冲输出为170mA/24VDC,可满足远距离传输及计数器脉冲输入端对脉冲信号的驱动。而通过PLC控制SIMATIC MICROMASTER420变频器可实现给料机的变速和启停。

When Siemens flow-meter （7MR1110-1DR70-2AA0-Z）, pulse generator （7MV1150-2AA00） and two OMRON counters are used in batch and accumulation for activator, impulse signal transducer （7MV1070-1AC10-0AA0）, whose input supplies 8.2V DC power for the pulse generator, and whose output supplies 170mA/24V DC signal, satisfies the needs of long-distance transmission and drive for counter input. The Frequency changer （SIMATIC MICROMASTER 420） controlled by PLC can realize the control for stopping or running and the speed change of the feeder.
