Sawtooth generator
You can adjust the current source value and get accordingly output voltage of the pulse.
Pulse output voltage - current source value
1.01V - 02mA
1.51V - 03mA
2.01V - 04mA
2.52V - 05mA
3.02V - 06mA
3.52V - 07mA
4.02V - 08mA
4.53V - 09mA
5.03V - 10mA
Thank you @UncleRick for explaining the working of relay :)
