Digital Output and Digital Input FET Modules

The Digital Output/Digital Input (DO/DI) FET modules have 16 or 32 configurable user
connections, organized in groups. Each group can be configured as an 8 DO group or as
an 8 DI group.
The outputs are optically isolated current sink FET type with back indication. The inputs
are optically isolated Dry Contact type with internal "wetting" voltage.
In the 32 DO/DI module, the following I/O combinations can be configured in the
ACE3600 STS site configuration:
I/O combination
32 DO
8 DI + 24 DO
16DI + 16 DO
24 DI + 8 DO
32 DI
In the 16 DO/DI module, the following I/O combinations can be configured in the
ACE3600 STS site configuration:
I/O combination
16 DO
8 DI + 8 DO
16 DI
The appropriate combination is selected as the I/O module type, when configuring the
I/Os in the ACE3600 STS site configuration.
Each DI can be configured as Fast Capture DI in the STS advanced I/O configuration.
Fast capture causes the SCAN ladder output operation to get the first change that
occurred since the previous scan. When fast capture is disabled (default), the scan gets
the current value of the DI (in this case DI changes between scans are missed).
Each input has a hardware input filter to make sure that the input reading is stable. The
hardware DI filter range is 0 to 50.8 mS (in 0.2 mS steps). Counter DI filter range is 0 to
12.75 mS (in 0.05 mS steps). The DI filter can be set in the STS advanced I/O
configuration.
Note: In this module, the minimum effective filter value is 1 mS.
