5.7 AIM104 – PULSE
The AIM104-PULSE board provides 16 opto-isolated digital inputs. Of these, the first 4 inputs may be used
as frequency (0-100 kHz) pulse inputs. The first 10 inputs may be used as low frequency accumulator pulse
inputs. Jumper options are included for each digital input to select a 10ms input debounce filter.

AIM104-PULSE Link Settings

Link settings on the AIM104-PULSE determine where the board's I/O will appear in memory. If more than
one AIM104-PULSE board is used, the first AIM104-PULSE in a Director should be addressed at Board #1,
and the second as Board #2.

Input Filter Selection
Each opto-isolated input channel can be set to include an input filter to reduce input errors caused by switch
contact bounce by setting LK 6 where
• Inputs 1 - 16 are LK6 A – P
Common Positive Input Selection
The positive side of each channel can connected to the positive side of the common isolated supply by
inserting the following links. This reduces the number of wire connections, since only one side (-ve) requires
an external connection. To switch ON the input, the –ve input terminal should be switched to the isolated 0V:
• Inputs 1 - 16 are Links LK4A-P, respectively
0.75 Watts, excluding loop power
-20 to +70 C
16 opto-isolated digital inputs
All may be used as status, or:
Inputs 1-4 may be frequency inputs
Inputs 1-10 may be accumulator inputs
10 V to 36 V
