General Electric IS220YTURS1A Primary Turbine Protection I/O Module

GE IS220YTURS1A is a Primary Turbine Protection I/O Module. It serves as an electrical interface between the IONet network and devices (such as speed sensors and flame detectors). It focuses on implementing the highest level of safety protection, triggering shutdown upon detection of hazardous conditions, for protect equipment.

Note: The IS220YTURS1A complies with safety standards. If the module fails or if external power or communication is lost, the system can enter a predefined safe state.

Function & Features

• Speed ​​Monitoring: The IS220YTURS1A provides up to four passive magnetoelectric speed sensor interfaces with a wide frequency range (2 Hz-20,000 Hz) for measuring rotor speed, which serves as the basis for overspeed protection.

• Flame Detection: The IS220YTURS1A processes up to eight flame sensor signals. It detects voltage pulses (>2.5V) and counts the pulses within a configurable time window to determine whether a flame is present.

• Electrical Parameter Monitoring: The IS220YTURS1A monitors bus voltage and generator voltage inputs, as well as shaft voltage and current signals (for monitoring bearing insulation condition, etc.).

• Configurable Parameters: Many parameters within the IS220YTURS1A module, such as the flame detection time window, are configurable based on the application. These parameters are indicated by (CFG) in the test documentation.
