Description
PROSOFT AN-X2-AB-DHRIO Communication module
AN-X2-AB-DHRIO used PROSOFT s7-200 PLC, a total of five I / O modules can be configured, each module on a total of 8 points, to meet the design needs. The general-purpose frequency converter adopts the IF 1.2.2K model in the SAMCO-i series. The given frequency of the inverter is given through the panel and controlled by the output terminals of the PLC.
PROSOFT AN-X2-AB-DHRIO according to the requirements of different frequencies to determine the frequency converter terminals FR, 2DF, 3DF and PLC output terminal connection method. Table 1 shows that there are four kinds of frequencies: 25Hz, 35Hz, 45Hz and 50Hz. By the PLC output signal to the inverter corresponding terminal combination to produce the above four kinds of frequency.
PROSOFT AN-X2-AB-DHRIO uses a transistorized DC output module. As the output stage of this non-contact switching circuit is an optocoupler, its power supply and the power supply of the internal control circuit of the frequency converter are isolated from each other, so there is no need to connect other devices to ensure that no malfunction will occur.
