hi,
i'm looking to control a double solenoid directional control valve the will reciprocate a cylinder on a mobile robot. i've tried to build a circuit to do this off of 27vdc using national instruments multisim program, but it keeps crashing after just on cycle or less. the solenoids will be 24vdc, but i'm not positive about the wattage, i saw one that had 3.5watt, but i have not decieded if i will us it or not.
i am thinking of using transistors as switches that are controlled by a limit switch.
any advice (or better yet, schematics) that you could give me would be great.
thanks in advance
