Servo Valve Positioner Module (SVPM) – CC-PSV201

Function

This Series C I/O module provides an onboard PID positioning loop for positioning a servo valve typically used in a turbomachinery control application. It can accept LVDT/RVDT/4-20 mA position feedback signals from the control valve, receive a control valve demand remote set point from a C300-20msCEE controller, and execute an onboard PID positioning loop to issue current output to the servo valve coil to control the control valve position.

Notable Features

  • Onboard PID positioning loop execution with overall loop latency within 10 mS
  • Onboard excitation supply for LVDT and support for various configurations of LVDT connections
  • LVDT input channel can be optionally configured to accept 4-20 mA analog input signal
  • Supports a wide range of unidirectional/bidirectional current output to servo valve coil
  • Servo valve output channel can optionally be configured for 4-20 mA analog output signal
  • Accepts two digital inputs, which can be configured to drive servo valve output to a safe value
  • PID execution using the position measurement and remote set point received from the C300 20 ms controller
  • Extensive module-level diagnostics (PV qualification for AI & AO, LVDT excitation frequency drift check, internal reference check, power supply diagnostic, memory diagnostics, etc.)
  • Extensive field-level diagnostics (open wire detection for Servo, LVDT, AI [4-20 mA] and DI; LVDT core fallout; read back current diagnostics for Servo and AO [4-20 mA])
  • Drive Servo output to a safe value on detecting abnormal conditions of control components
  • Point processing at 2.5 mS period for "LVDT/RVDT signal" and PID execution
  • Provides digital dither (current modulation) to compensate stiction in the controlled device (servo valve)
  • Supports servo valve position calibration
  • Supports redundant solution
  • Supplies non-incendive field power

SVPM Supports the Following I/O Interfaces

  • LVDT/RVDT/analog input – 2 channels
  • Digital input – 2 channels
  • Servo/analog output – 2 channels
  • 2 PID blocks
