Relay control for up-and-down slope circuit

Published:2011/7/12 9:54:00 Author:John | Keyword: Relay, up-and-down slope

Relay control for up-and-down slope circuit is as shown, for which the DG387 CJ solid state relay has been used to achieve the switch from the upper slope to the lower slope. When the servo is at the new zero position, it slows down. The slope rate depends on the regulation position between R1 and R2. The circuit is with a low cost but to ensure the best response of the servo system. When input signal detected by A1 is not zero, the optical isolator A3 is started to drive the A4 to do the switch. Positive slope generated by A5 drives the system load to move towards the desired position. Thus, the control input voltage of servo feedback is driven to reduce input power.   (View)
