Electro-Pneumatic Positioner

An I/P module with consequent pneumatic intensifier is utilized to control the pneumatic actuator. The well-demonstrated I/P module relatively changes over the lasting electrical setpoint motion from the CPU into a pneumatic flag used to change a 3/3-way valve. The wind current for pressurizing or depressurizing the actuator is persistently balanced. Subsequently, fantastic control is accomplished. 
When achieving the set point, the 3/3-way valve is shut in focus position to limit the air utilization. Four diverse pneumatics adaptations are accessible: for single-acting or twofold acting actuators, each with "safeguard" or "come up shortstop" work.
