Information

Overview Manuals Common Applications Product Precautions
Westinghouse 1C31192G01 provides the field interface for the tachometer signal used by the 1C31189G01 Ovation speed-detector electronics module.
  • Provides one speed-sensor interface for the documented speed detector personality module function.
  • Handles tachometer field input through the specified Ovation I/O subsystem.
  • Works with 1C31189G01 speed-detector electronics module.
  • The personality module supports the terminal connection for the documented speed-detector subsystem.

The speed detector personality module belongs in the controlled Ovation I/O subsystem and works with 1C31189G01 speed-detector electronics module. Its field connection, companion hardware and project configuration must be reviewed together before the channel is returned to service.

Important Notice: Use 1C31192G01 only with 1C31189G01 speed-detector electronics module; verify the field interface and controlled configuration before energizing the subsystem.

Westinghouse 1C31192G01 Official Technical Reference Excerpt (PDF)Westinghouse 1C31192G01 Installation & Commissioning Guide (PDF)

The first document covers the product function, system role and technical selection. The installation guide covers identification, connection checks, commissioning and the acceptance record.

Installed-base maintenance
Restores the documented speed detector personality module position without changing the approved system architecture.
Loop or channel service
Supports verification of tachometer field input at the assigned control-system channel.
Planned replacement
Provides an exact-identity replacement path when 1C31189G01 speed-detector electronics module and the field interface have been confirmed.
Commissioning support
Allows the responsible engineer to prove wiring, configuration, status and response for one speed-sensor interface.
Before installing Westinghouse 1C31192G01, confirm the documented system, interfaces and controlled configuration.
1
Match the complete 1C31192G01 marking to the work order and installed position before removal.
2
Confirm 1C31189G01 speed-detector electronics module before making or breaking any field connection.
3
Keep the assigned tachometer field input within the documented subsystem and range.
4
Record terminal designations, polarity, common and shield treatment before disconnecting conductors.
5
Inspect module seating, connector keying, terminal condition and strain relief before power is restored.
6
Restore the controlled channel configuration, range selection and alarm or timeout behavior after installation.
7
Check local indicators and controller diagnostics for internal, communication or channel faults during commissioning.
8
Prove the intended response across one speed-sensor interface and record the acceptance result before release.

Technical notes

Use 1C31192G01 only with 1C31189G01 speed-detector electronics module; verify the field interface and controlled configuration before energizing the subsystem.

FAQ View All FAQ

  • What field signal enters Westinghouse 1C31192G01?
    The personality module accepts the speed-detector subsystem's sinusoidal or pulse-train tachometer connection.
  • Which electronics module requires Westinghouse 1C31192G01?
    Its documented companion is the 1C31189G01 speed-detector electronics module.
  • How does Westinghouse 1C31192G01 support both overspeed and regulation measurements?
    It supplies the common tachometer interface from which the paired electronics develops the 16-bit overspeed and 32-bit speed-regulation values.
  • What overall frequency coverage is associated with Westinghouse 1C31192G01?
    Across the two documented outputs of the paired subsystem, the input coverage extends from 0.72 Hz to 65,535 Hz.
  • Does Westinghouse 1C31192G01 perform the speed calculation?
    No. It provides the sensor-side personality interface; 1C31189G01 performs the speed-detector processing.
  • Why should tachometer waveform type be recorded for Westinghouse 1C31192G01?
    The installed sensor may present a sinusoidal or pulse-train signal, and the replacement wiring and acceptance test must reproduce that actual waveform.
  • What terminal-path check is needed on Westinghouse 1C31192G01?
    Trace the single tachometer input from the field connection through the personality module to 1C31189G01 and confirm the shield and signal conductors retain their assignments.
  • How can Westinghouse 1C31192G01 be accepted after a maintenance change?
    Inject or observe a known tachometer frequency and verify that both corresponding speed values from the paired electronics remain stable and plausible.
