GE DS3800NGRA1L1E

Connectors: It has 2 34 - pin male connections and 2 40 - pin male connections.
Components: There are 25 circuits on the board. It mainly uses ceramic - covered metal film resistors, polyester film capacitors (such as.047 + / - 10% m/e ae 80 V, 708a1 m/e 100V 2.0 + / - 10%, and 708a1.33 + / - 10% a/e 200 V), ceramic capacitors, and fixed vacuum capacitors. The board also includes components like voltage comparators that can operate from a 5.0 V single - power supply, retriggerable one - shots, hex inverters, quad spst cmos analog switches, and precision operational amplifiers with low input bias and offset currents.

Functional Features:

The board’s components, such as voltage comparators and precision operational amplifiers, enable it to perform functions related to voltage regulation and signal processing. The retriggerable one – shots can generate output pulses with a wide range of durations, and the analog switches and inverters help in signal manipulation and control.
As a regulator board in the Mark IV series, it plays a role in regulating and controlling the relevant parameters in the steam/gas turbine management system.

Application Scenarios:
It is used in the Mark IV series system for steam and gas turbine management. It can be applied to automate the startup, shutdown, and cooldown procedures of turbines, and ensure that the entire system operates within safe parameter ranges.
