9.6 The 466 Analog Input Module
9.6.1 Design
The module is designed as a plug-in PCB for central controllers and
expansion units with a backplane connector and with a blade connector to
accept a plug-in front connector. You can directly connect the process signal
lines to the front connector, which is available separately, with screw or
crimp terminals.
9.6.2 Special Features of the 466 Analog Input Module
The 466 analog input module processes the digital input signals by encoding
the instantaneous value; periodic system interference is therefore not
suppressed.
You select the measuring ranges with a switch setting for every four
channels.
9.6.3 Startup
The mode of the 466 analog input module must be set exclusively via
switches on the board. Figure 9-26 shows the designations and locations of
switches on the board.
