ABSTRACT:
A control circuit for driving solenoids protects these devices from failure due to overheating caused by frequent on-off cycling. Control signals are passed through logic gates. A timer responds to the termination of a control pulse and disables the logic gate that passes signals to the load for a predetermined time, thus restricting the minimum off time of the solenoid. Minimum on time or maximum on or off times are not affected.
