The entire project is to test the timing of an actuator. I need the actuator to pulse on a 37msec square wave while the timer/counter counts the number of pulses. The actuator is driven from the output of the relay (AC).
So when everything is working - the square wave will go to the relay switching it on and off. The relay will then control the actuator turning it on and off in tiny pulses. The counter will count the number of pulses. The operator will run the actuator 20 degrees then check the number of pulses. It should be within a defined range in order to 'pass'. Then he/she will do the same in reverse or counter-clockwise.
So now, I just got back to my desk from the test bench. The problem is definitely with the SS Relay. I disconnected the relay and my o-scope showed me a beautiful, perfect 14.5V square wave. This was unexpected as I thought my input was only 6V so I checked the input and it too was 14.5V. So I am concluding that the relay is sucking some major amperage. Luckily, my chip didn't burn like the last 5 or 6.
I reconnected the relay and disconnected the timer and got the same 3V square wave as before. So the timer doesn't seem to add any to the problem.
This test was done without being connected to the actuator.
