Achieving stable high-speed drive and high-precision control.
■Features The CA350-011 is a servo amplifier for driving direct-acting servo valves. It controls the displacement of the servo valve's spool position in proportion to the command input voltage. It employs a PWM method for output, enabling stable high-speed drive. The displacement signal from an LVDT sensor installed on the spool part of the servo valve is fed back as a voltage value, allowing for high-precision control. The main circuit board is housed in a compact and lightweight resin case measuring 100×139mm. The input voltage is +24V, and power can be supplied either from the rear connector or the bottom DIN rail. When using the DIN rail, it is also possible to connect and configure multiple amplifiers in parallel to power the entire system collectively. For command signal input, either the BNC terminal on the panel or the D-sub terminal for monitoring can be selected. The monitoring output uses this D-sub terminal to output displacement monitor values and current monitor values as voltage equivalents. Additionally, by using an externally connected switch, the output can be directly turned on or off.

Company information
Our company is engaged in the research, development, design, manufacturing, and sales of high-precision pneumatic servo valves. In addition to our existing lineup, we also accept development requests tailored to customer needs and applications. In the field of pneumatics, where fine control is extremely challenging, we have achieved high-precision servo control, which is primarily adopted in semiconductor manufacturing equipment and railway vehicles. We also manufacture some hydraulic equipment, and our servo valves are actively used in testing machines, general industrial machinery, and robotics. Furthermore, we handle not only the hardware aspects such as servo valves and actuators but also the software components like drive amplifiers and controllers, allowing us to provide these as an integrated system. We have established a factory within the company, creating an environment where we can deeply pursue manufacturing and quickly realize our customers' requests. We will continue to strive daily to be a professional group in pneumatic servos. Please feel free to contact us with any requests.
