6.7 Configuration
Switches
The SCADAPackl32 SCADAPack 32P SW1 is an eight position DIP switch. The first seven
switches on SW1 are used to configure digital / counter input filtering and analog input and output
ranges. SW1 is shown in the following diagram. Refer to
5232 Controller Board Field Wiring
for the location of SW1 on the SCADAPack 32P SCADAPack 32P.

6.7.1
Digital Input Filters
Each of the three digital / counter (DIN/Counters) inputs on the SCADAPack 32P SCADAPack 32P
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 32P SCADAPack 32P SW1, switches Filter 0, Filter 1 and Filter 2 switches control the
input filter functions.
•
Filter 0 for DIN/Counters input 0.
•
Filter 1 for DIN/Counters input 1.
•
Filter 2 for DIN/Counters input 2.
