CC-PSV201 Honeywell Series C Servo Valve Positioner

CC-PSV201 Honeywell Series C Servo Positioner

Product Introduction

This Honeywell servo positioner represents a specialized solution for critical turbomachinery control within the Experion PKS architecture. Primarily, the unit provides an integrated PID positioning loop that executes with a total latency of less than 10 milliseconds. For instance, the CC-PSV201 can accept feedback from LVDT, RVDT, or standard 4-20 mA analog signals to ensure accurate valve placement. Furthermore, the hardware manages high-speed current outputs to drive servo valve coils across various industrial ranges. Specifically, the onboard processor calculates the necessary adjustments based on remote set points received from a C300-20msCEE controller. Additionally, this module includes advanced digital dither functionality to compensate for mechanical stiction in the controlled device. Finally, the CC-PSV201 supports redundant configurations to maximize system uptime in mission-critical applications.

Technical Specifications for CC-PSV201

The SVPM hardware utilizes high-resolution 16-bit DACs to deliver precise control signals to the connected servo valves. Specifically, the module supports both  Chaotic and unipolar current ranges, including values up to 320 mA. Meanwhile, the input section features an ultra-fast scan rate of 2.5 milliseconds for LVDT and RVDT signal processing. Regarding analog capabilities, the CC-PSV201 provides two dedicated channels that users can configure for standard 4-20 mA inputs or outputs. Moreover, the unit includes two digital inputs that operators can program to drive the valve to a pre-defined safe state. Specifically, the LVDT interface provides an internal excitation supply of 8 V RMS at frequencies up to 3.2 KHz. Consequently, the CC-PSV201 ensures reliable feedback even in electrically noisy industrial environments.

Mechanical and Environmental Parameters

The physical design of this servo module focuses on safety and signal integrity for demanding power and energy sectors. For instance, the hardware provides galvanic isolation of ±500 VDC to protect internal circuitry from field-side voltage spikes. Additionally, the CC-PSV201 performs extensive self-diagnostics, including memory checks and power supply monitoring, to ensure continuous operation. Specifically, the field-level diagnostics can detect open wires in the servo, LVDT, and analog input circuits. Meanwhile, the module maintains a low temperature drift of 300 ppm per degree C for its current output channels. Furthermore, the system includes non-incendive field power supplies to enhance safety in hazardous areas. Therefore, the CC-PSV201 maintains high accuracy while operating within standard Series C environmental specifications.

Installation Guide for CC-PSV201

Installing this positioner module requires careful attention to wiring configurations for various LVDT types and servo coils. First, mount the CC-PSV201 onto the Series C I/O termination assembly while ensuring the power is switched off. Specifically, verify the LVDT wiring follows the 3, 4, 5, or 6-wire setup required by your specific field instrument. Next, configure the PID parameters and dither settings within the C300 controller software to match the valve's mechanical properties. Furthermore, users should perform a full calibration of the servo valve position using the integrated software tools provided. Specifically, check the resistance of the servo coil to ensure it falls within the allowed limits for your selected current range. Finally, test the digital safety inputs to confirm the module drives the valve to its fail-safe position correctly. For related parts, visit our Honeywell Series C section.
