About the DS3800NFIB1D1C

The DS3800NFIB1D1C is a printed circuit board by General Electric which was designed to fulfill a function of the Speedtronic Mark IV series. The Mark IV series is a system of turbine controls. These systems regulate the operation of gas and steam turbines. The Mark systems have been counted on for five decades to control turbines since the first Mark I series made in the late 1960s. The technologies utilized in the Mark systems have been developed, refined, and perfected since the 1940s. The Mark IV controls liquid and gas fuel within the parameters of the turbine’s load control and speed requirements. The Mark IV regulates temperature and water and steam injection. The Mark IV controls the automatic turbine operations of cool down, shut down, and startup. A very useful diagnostic system is featured on the Mark IV. This diagnostic system is very important for troubleshooting.

The DS3800NFIB1D1C is what is called a fan loss printed circuit card. A fan loss circuit card’s main function is to protect the turbine system from the dangers of overheating. Contacts open in the case that a power unit fan stops functioning. If there is a fan loss, the turbine operations in a drive stop circuit is stopped by the thermostat contacts. This minimizes the danger of the turbine overheating due to functioning under load without cooling of forced air provided by a fan. Overheating due to operating without sufficient air flow can cause damage to the power unit.

Technical support and troubleshooting as well as datasheets and user manuals for the DS3800NFIB1D1C were originally provided by GE.
