DS3820RPSA

GE Speedtronic Mark IV DS3820RPSA is a Servo Module and is part of the gas turbine control systems with Mark IV Series and functions as an Overtempt trip module. The DS3820RPSA component is a circuit board with a metal frame attached to it. Two short sides and two taller sides make up this frame. Top and bottom hat flanges finish the two taller sides. The bottom flange has screw mount cutouts, whereas the top flange is drilled in multiple places. A number of stab-on connectors with surface wired connectors are included on the DS3820RPSA circuit board.

There are several high-voltage capacitors, as well as resistors and diodes, in this circuit. The board contains 10 connectors on the surface that can be used to connect to other components. Servos are used to convert low-power command signals into higher-voltage and higher-current signals.
