FUNCTIONAL DESCRIPTION:
IC3600SSZA1 is a Servo Valve Control Card manufactured and designed by General Electric as part of the Mark II Series used in GE Speedtronic Control Systems. This card functions as an analog amplifier designed to receive an analog input voltage of +/- 10V, which is used to control servovalves. The amplifier adjusts the current output, which can be fine-tuned through a set of DIL switches on the board. These switches allow for current adjustments in 10mA steps, with a maximum output of 300mA. The current output is regulated in a closed-loop configuration, ensuring precise control regardless of the power supply's stability or the resistance variations in the solenoids. Additionally, the card is equipped with an embedded auxiliary power supply, providing both positive and negative voltages to support the operation of an external potentiometer. This ensures reliable and consistent performance in a range of applications where precise current control is required.
SERVO VALVE CIRCUITS:
In applications requiring precise control of position, speed, or force, such as rolling mills that manage metal thickness to within ±0.0005 in. at speeds of 2500 to 3000 ft/min, on/off or proportional solenoid valves are inadequate. Achieving these tight tolerances demands more than basic hydraulic control systems.
Servo directional valves are the only hydraulic valves capable of precisely controlling oil flow and pressure at high speeds. These 4-way, 3-position spool valves block all ports in the center position. Typically, servovalve spools are controlled by high-pressure pilot oil, and many are equipped with feedback mechanisms to ensure accurate and repeatable positioning from a given input.
SERVOVALVES FOR ACCURATE POSITIONING OF ACTUATORS:
The ability of a servocircuit to provide real-time feedback and adjust the position based on this data makes it highly effective for processes requiring rapid and repetitive movement. The closed-loop feedback ensures minimal deviation from the target position, compensating for any variations that might occur due to factors like pressure fluctuations, load changes, or resistance in the system. In applications where a cylinder must rapidly move to various positions with high accuracy, typically within a tolerance of less than ±0.020 in, a servocircuit is the optimal solution for achieving this level of precision.

What is a Servo Valve Control Card?
A Servo Valve Control Card is an electronic device used to control the operation of a servo valve. It regulates the flow and pressure of hydraulic fluids in a closed-loop system, enabling precise control of the position, speed, and force of actuators such as cylinders or fluid motors.
What is the typical input for a Servo Valve Control Card?
The typical input for a Servo Valve Control Card is an analog signal, often in the range of ±10V, which corresponds to the desired position or speed of the actuator. The card then processes this signal and adjusts the valve to meet the specified requirements.
How precise is the control provided by a Servo Valve Control Card?
Servo Valve Control Cards provide highly precise control, with tolerance levels often as tight as ±0.020 in. in applications like rolling mills or high-speed CNC machines. The closed-loop feedback ensures that the valve adjusts continuously to maintain the desired position or force with minimal deviation.
