Note:
The default setting for the optional analog outputs is the 0% offset with output signals
ranging from 0-20mA in current mode or 0-5V in voltage mode.
11.6 Line Frequency Selection
The SCADAPack controller may select a 50 or 60 Hz line frequency for digital and analog input
processing. Switch ‘Options 3’ on SW1 selects this option. On the SCADAPack P4 or P4A, press the
left side of dip switch as shown in the figure below to select the 60Hz line frequency and the other
side of the switch to select the 50Hz line frequency. On the SCADAPack P4B, select these settings
when via software as the 5606 I/O section of the manual.

11.6.1 Digital Input Filters
Each of the three digital / counter (DIN/Counters) inputs on the SCADAPack 32 controller board can
be filtered. Filtering limits the maximum digital input or counter frequency to approximately 30Hz.
• Use a filter for 50 or 60Hz digital inputs and for low speed counting applications that experience
problems due to contact bounce.
• Do not use filtering for high speed counting applications.
SCADAPack 32 controller board SW1, switches Filter 0, Filter 1 and Filter 2 switches control the
input filter functions.
• Filter 0 for DIN/Counters input 0.
