IS200TRPAH1BEC is a Turbine Primary Trip Terminal Board developed by GE. It is a part of Mark VIe control system. The turbine primary trip terminal board plays a crucial role in turbine control systems, particularly within the Mark VIe system. It accommodates either 12 passive pulse rate devices (four per R/S/T section) or six active pulse rate inputs (two per TMR section). These devices sense a toothed wheel to accurately measure turbine speed, providing essential feedback for control and monitoring purposes.
One of the fundamental aspects of speed input management involves the wiring configuration for pulse inputs. With TRPAH1A, there are distinct guidelines for wiring to different sets of pulse inputs, each tailored to specific requirements:
In addition to wiring configurations, jumper settings also play a crucial role in managing speed input connections, particularly for the bottom pulse inputs. Here's a breakdown of jumper configurations:

What is IS200TRPAH1BEC?
It is a Turbine Primary Trip Terminal Board developed by GE under the Mark VIe series.
How are the trip relays constructed?
Trip relays are constructed using sets of six individual form A devices arranged in a voting pattern. Any two controllers that vote to close will establish a conduction path through the set, enabling the relay to actuate.
Why is detection of a shorted relay important?
Detection of a shorted relay is crucial to preserve tripping reliability. In the event of a shorted relay, it's essential to identify the issue promptly to prevent potential malfunctions or safety hazards.
How does the sensing circuit work?
A sensing circuit is applied to each set of relays. When the relays are commanded to open and voltage is present across them, the circuit detects if one or more relays are shorted. This detection signal is then transmitted to the PTUR I/O pack to create an alarm, alerting operators to the presence of a shorted relay.
How does the sensing circuit ensure reliability?
The sensing circuit utilizes relay commands from all three packs to avoid false indications. By incorporating inputs from multiple controllers, the sensing circuit mitigates the risk of false alarms, particularly in scenarios where one PTUR I/O pack votes differently from the others.
