Product Features
GE IS215VPROH1BD supports vibration sensor (e.g. speed, acceleration), temperature sensor (RTD, thermocouple) and pressure transmitter signal access, and can handle standard signals such as ±10V, 4-20mA.
GE IS215VPROH1BD has 4 C-type relays (normally open/closed optional) + 2 trip contacts (user configurable) for emergency shutdown or alarm triggering.
GE IS215VPROH1BD supports the TMR redundancy system, which realizes redundant signal transmission through dual terminal boards and D-shell connectors to ensure normal operation of the system in case of a single point of failure.
GE IS215VPROH1BD can monitor the turbine speed in real time through a redundant channel independent of the main control system, and trigger a trip immediately when a preset threshold is exceeded.
GE IS215VPROH1BD monitors the phase difference between generator and bus voltage to prevent non-simultaneous grid connection.
GE IS215VPROH1BD monitors the signal validity (e.g. disconnection, short-circuit) in real time and displays the channel status through LED indicators.
GE IS215VPROH1BD supports Ethernet (IONet) communication and can interact with the main controller to realize remote monitoring and parameter configuration.
Product Using Principle
GE IS215VPROH1BD is configurable to measure the operation data of the turbines (e.g. vibration amplitude, bearing temperature, speed) from external devices such as vibration sensors, temperature sensors, etc., which via the on-board circuit are filtered, amplified and then converted into digital signals before transmitting to the Mark VI main controller.
Up to 8 sensors (vibration acceleration sensors) can be connected to the main controller, the signals will be analyzed by the controller according to the preset algorithm (such as API 670 standard ) and when a certain parameter exceeds a threshold value, it will drive a actuated device (such as cutting off fuel supply by actuated valve, triggering a mechanical brake) by 4 relay outputs.and reach a rapid shut down hardware level with two Trip relay output.
Implementation in a TMR circuit with 3 IS215VPROH1BD modules where the signals are processed coherently by the three modules, maintain a common output signal (as long as the majority are not in alarm) the majority voting approach, and failing of an individual module, must be detected in an automatic way and switch automatically to the backup channel.
