Servo Motors

Product Overview

The Honeywell CC-PSV201 is a Series C I/O module designed for turbomachinery control.
It provides precise servo valve positioning via an onboard PID loop, supporting LVDT, RVDT, and 4-20 mA feedback signals.
The module ensures high-speed, accurate control and integrates safety and diagnostic features for industrial environments.

Key Features

• Onboard PID Control: Fast 10 ms loop latency for precise valve positioning.
• Wide Input Support: Accepts 3/4/5/6-wire LVDT, RVDT, and 4-20 mA analog signals.
• Flexible Output: Bipolar/unipolar current outputs, configurable 4-20 mA analog output.
• Safety & Redundancy: Two digital inputs drive output to safe value; supports redundant configurations.
• Diagnostics: PV qualification, excitation frequency drift check, open-wire detection, and readback current monitoring.
• Digital Dither: Adjustable 25–60 Hz to reduce servo valve stiction.
