Functional Description

IS230TNPAH1A is a Primary Trip DIN-Rail Module manufactured by General Electric. It is a part of the Mark VIe Control System. The module is specifically designed to facilitate primary trip functions within the Mark VIe Control System. Primary trip functionality refers to the system's capability to initiate the shutdown or trip of equipment or processes in response to predetermined conditions or events. These conditions could include abnormal operating parameters, safety concerns, or critical fault occurrences. As a DIN-rail module, it can be easily mounted on DIN rails, which are standardized metal rails widely used for the installation and organization of electronic components within control cabinets or control panels. DIN-rail mounting ensures secure and efficient integration of the module into the overall control system. The module's primary purpose is to provide a reliable and efficient mechanism for executing the primary trip function within the Mark VIe Control System. This entails responding to specific triggers or signals and initiating the necessary actions to shut down or trip the equipment or process in a controlled and safe manner. The module is designed to interface seamlessly with other components of the Mark VIe Control System to ensure precise and accurate execution of the primary trip function.


  • Feedback from the shorted contact detector: The feedback from the shorted contact detector is checked to ensure that the control signal is functioning correctly. If there is a problem with the control signal, indicating a shorted contact, an alarm is generated to alert the operators or maintenance personnel of the issue.
  • Feedback from the ESTOP/TRP input: The feedback from the Emergency Stop (ESTOP) or Trip (TRP) input is monitored to ensure the proper functioning of the signal. If there is a problem with the signal, indicating a fault or failure in the ESTOP or TRP circuit, a fault indication is generated to highlight the issue and initiate the necessary actions.
  • Feedback from speed pickup fanning jumpers: The feedback from the speed pickup fanning jumpers is checked to ensure that the intended speed pickup configuration matches the actual position. If there is a mismatch between the intended and actual positions, indicating a potential misconfiguration or wiring issue, an alarm is created to prompt investigation and resolution.
  • If any of the above diagnostic signals are found to be unhealthy or indicate a fault, a composite diagnostic alarm called DIAG_PTUR is generated. This alarm serves as an overall indication that there is a diagnostic issue within the terminal board or associated components.
  • The diagnostic signals can be individually latched, meaning that once an unhealthy signal is detected, it remains latched even if the signal returns to a healthy state. These latched signals can then be reset using the RESET_DIA signal once the underlying issue has been resolved and the signals return to a healthy state.

What is IS230TNPAH1A?
It is a Primary Trip DIN-Rail Module manufactured and designed by General Electric

What should be done if the user does not require or use an ESTOP?
If an Emergency Stop (ESTOP) function is not needed or utilized, it is recommended to jumper the local TRP power source (P24O/R) to the respective TRP inputs at the terminal board. This effectively connects the power source to the TRP inputs, ensuring proper functionality of the associated relays.

What type of power source should be used for the ESTOP function?
The ESTOP function should be connected to a clean DC power source, such as a battery or a rectified AC source with less than 5 percent ripple. Using a clean power source helps ensure the reliability and stability of the ESTOP function, minimizing potential interference or false trips.

What is the minimum voltage requirement for the TRP inputs?
To ensure proper operation, there must be a minimum of 18 V DC at the TRP inputs. This voltage level is necessary for reliable performance and allows for adequate signal detection and relay activation.
