I am working on a project that requires basically 5 timers.
It is for the clocking of a sequencer. The sequencer basically works like this:
There are 5 sets of contacts on the sequencer that open and close at different time intervals.
Applying the appropriate voltage to the sequencer starts a timer. After 1-30 seconds a set of contacts close, then another, then another...etc.
The way that contacts close is by a Thermal heater that heats a thermal disk conected to the contacts. The conatcts are "GANGED" together, and the sequencer is built by choosing different time rated contacts at the time of assembly.
I would like to use a Picaxe controller as a base for the tester that checks these devices for proper operation.
My requirements would be that it monitor 5 sets of contacts, Provide an output to control a power relay (through a transistor or driver) to turn on the power (24VAC), and provide the timing of these units to either a computer screen or an LCD display.
Can someone recommend a Picaxe controller that would work for this application? Also any other information/Advice would be welcomed.
