- Corrections & Additions for Your Pneumatic Circuit Drawing Pneumatic Valves Each linear actuator must be controlled by a directional control valve (DCV) (e.g., 5/2 or 4/2 valve). The bi-directional motor requires a reversible valve to change rotation direction. Pressure Regulators & Air Supply Include two pressure regulators as per the assignment requirement. Show the main compressed air supply line connecting all components. Limit Switches & Safety Features Attach limit switches to each actuator to detect positions. Implement a two-handed push-button safety system to control actuator movement. Connections Between Components Draw air supply lines linking the compressor, valves, and actuators. Clearly label all inputs and outputs for better understanding. Next Steps: Revise your diagram to include these missing elements. Ensure all components follow correct safety and operational requirements.arrow_forwardFor the following circuit, What is Vout as a function of R and Id assuming the op-amp is ideal.
