DS3800DFPF is a Firing Circuit Daughter Board manufactured and designed by General Electric as part of the Mark IV Series used in GE Speedtronic Gas Turbine Control Systems. A firing circuit daughter board is a component of an electronic system that is responsible for controlling the firing or activation of certain devices. Here are some key points about firing circuit daughter boards:


Firing circuit daughter boards are often used in applications where precise control of the timing and duration of electrical pulses is crucial. This can include applications like motor control, power inverters, or any system where controlled firing of electronic switches is necessary.

Electronic Switching:

These boards are commonly associated with controlling semiconductor devices such as thyristors, SCRs (Silicon-Controlled Rectifiers), IGBTs (Insulated Gate Bipolar Transistors), or MOSFETs (Metal-Oxide-Semiconductor Field-Effect Transistors). These devices are often used in power electronics for switching high voltages and currents.

Timing and Triggering:

The firing circuit daughter board is responsible for generating the necessary signals to trigger these electronic switches at precise moments in the electrical cycle. This ensures the efficient and controlled operation of the overall system.

Isolation and Protection:

In some applications, the firing circuit board might include isolation and protection features to safeguard the control system from electrical noise, voltage spikes, or other potential issues.


Depending on the specific application, these boards may need to be customized for different control strategies, voltage levels, and current requirements.


The daughter board is typically integrated into a larger system, and it communicates with the main control unit to receive instructions and feedback about the status of the system.

Cooling and Thermal Management:

In high-power applications, thermal management is crucial. Firing circuit boards may include components for cooling, such as heat sinks or fans, to ensure proper operation under varying load conditions.

Feedback and Monitoring:

Some firing circuit daughter boards may incorporate feedback mechanisms to monitor the performance of the controlled devices, enabling the system to adjust its operation based on real-time conditions.
