K108 Pulse
Counter Lite
(freeware) The K108 Relay board from DIY/Kitsrus
(www.kitsrus.com) features 8 computer-controlled relay channels. It also includes 4 digital (on/off) type input ports. This software makes use of the Inputs to count pulses coming from an external device. The external device could be (for example) a photodetector for counting widgets on a factory production line or, it could be the pulse output from a liquid flowmeter, for counting the volume of fluid
flowing through a pipe in a solar heating system.
There is an alarm setting for each Input port, to trigger a warning when a specified count is reached. The alarm can also be
configured to operate a relay if desired.
Software features:
- 4 channels of pulse counting
- display total pulse count and average time between pulses
- configure volume or quantity per pulse, and display total and
average hourly rate
- option to configure alarm setting for max value
- option to operate a relay when max count setting is reached
- count info can be saved to file
- 8 channels of relay control, either manual,
or linked to Inputs or count alarms
- logging of input, relay, and other events
- user-configurable "friendly" names for Inputs and
Relays
- option to add user comments to the Log
- selectable Com port, with option to auto-connect at program start
- config settings are saved to file

Change Log
Jul 03/09 1.1.1 (30)
- fixed bug with Com port config settings
- modified Input state detection to prevent false counting
on long closed states.
- fixed a couple of display bugs with Count info
- added user-config names for relays and inputs
- added simple logging function
- added config settings for Log
- log is saved as tab-delimited text file
- some visual layout adjustments
- updated Help file
Jun 13/09 v. 1.0.1
- First release Notes:
a. The program uses GDI+ for some of the graphics display.
Win2000 (and Win98) may need the gdiplus.dll file to
be downloaded from Microsoft.
b. See the Help file, re load capabilities of the K108
relays for your application.
c. Sample pulse-generating products...
- The DIY/Kitsrus Kit79 and K130 are photodetector circuits that have relay
contacts
that can be used for generating a pulse.
- This page shows a flowmeter that has a pulse output:
