Hier ist alles, was Sie wissen müssen
The Analog Output Module (cat. no. 1771-OFE1) is an intelligent block transfer module that converts binary or four-digit BCD values (supplied by your processor) to analog signals at its four module outputs. The module accomplishes the data transfer with block transfer programming.
Block transfer write (BTW) programming moves up to 13 words of data from the processor to the module for digital to analog (D/A) conversion in one program scan. This information is converted to analog signals and is sent to the appropriate output channels. A block transfer read (BTR) moves five words of data from the module to the processor data table, if desired, for diagnostic purposes.
The module has a scaling feature that converts data sent to the module in engineering units to the proper analog signals. You may connect up to four analog output devices--such as valve positioners, motor speed controllers, signal converters or recorders--to the analog output module’s four channels. All analog output device inputs should conform to the voltage or current ratings of each module output channel.
In the programmable controller system, the analog output module provides the following functions:
