4.6 Analog Output (FMA) Selector
4-13
Chap. 4 BLOCK DIAGRAMS FOR CONTROL LOGIC
The block diagram shown in Figure 4.5 shows the process for selecting and processing the analog signals to be
outputted to the analog output terminal [FMA]. Function code F31 determines the signals to be outputted to
[FMA]. Function code F30 scales the output signal to a level suitable for the meters to be connected to the [FMA]
terminal.
The output voltage range is 0 to 10 VDC and the maximum allowable load current is 2 mA. This is capable of
driving two analog voltmeters with a common rating.
The test analog output is full-scale voltage output that adjusts the scale of the connected meter.
