Features:
- Measures the frequency of one sinusoidal or pulse-train speed sensor.
- Provides separate 16-bit overspeed and 32-bit regulation outputs.
- Detects open sensor wiring and overspeed conditions.
The current configuration is 1C31192G01, the personality-module half of the Ovation speed-detector subsystem paired with 1C31189G01 electronics.
The subsystem converts tachometer frequency into fast low-resolution data for overspeed protection and high-resolution data for speed regulation.
Before installation, match the electronics revision and sensor characteristics, then preserve the documented twisted-pair shield, trip-relay and grounding connections.
Availability is subject to Apter Power inventory and sourcing confirmation.

- Measures rotating-equipment speed from a dedicated tachometer signal.
- Provides a 5 ms low-resolution value for overspeed detection logic.
- Provides a variable-update high-resolution value for closed-loop speed regulation.
- The 16-bit speed value updates every 5 ms across its documented frequency range.
- The 32-bit speed value uses a configurable pulse count to determine its update period.
- Trip-relay status and overspeed indications are available to the configured Ovation points.
- Open sensor wiring can be detected when the source resistance is 5 kΩ or less.
- Overspeed status is evaluated separately from the continuous speed values.
- Input amplitude limits vary with sensor frequency and the revision of the paired electronics module.
- The module operates from 0 to 60°C in the specified Ovation cabinet environment.
- The permissible storage range is -40 to 85°C.
- Humidity must remain from 0 to 95% without condensation.
