About the DS200TCTLG1A
The DS200TCTLG1A is a Steam Turbine Trip Board, otherwise known as a Steam Turbine Reheat Board, that was initially created by General Electric. This DS200TCTLG1A Steam Turbine Reheat Board's Mark V Series is considered to be one of the final General Electric Mark product series to feature the patented Speedtronic control system technology in its products, which comes in handy for this DS200TCTLG1A PCB's specified applications in the control and management systems of steam, wind, and gas turbine automated drive assemblies.
This DS200TCTLG1A Steam Turbine Reheat Board alters the original DS200TCTLG1 parent Steam Turbine Reheat Board through its attachment of a singular, A-rated functional product revision.
Hardware Tips and Specifications
The DS200TCTLG1A is also known as a turbine trip circuit, and is populated by its own series of hardware components and component specifications to gain its specific Mark V Turbine Control System Series functionality. This DS200TCTLG1A board is a part of the master trip circuit and the protection core within its greater Mark V Series automated drive assembly. This circuit has:
- at least two sets of primary trip relays (PTR1 & 2)
- the PTRs are typically controlled by other boards like the TCQA
- three sets of three emergency trip relays (ETR1 & 2)
- while the ETRs are controlled by TCEA boards
If there becomes an issue with two of the three relays in this system, it will cause the turbine to trip.
The DS200TCTLG1A also has other features than the trip relays. It possesses four auxiliary control outputs that include an oil test solenoid, a mechanical lockout solenoid, an oil reset solenoid valve, and an electrical lockout solenoid. The DS200TCTLG1A can be used to perform the actual electrical overspeed trip test, the mechanical trip piston test, the actual mechanical overspeed trip test, the TMR cross trip test, the electrical overspeed trip test (online), the electrical trip test, the electrical overspeed trip test (offline), and the emergency over speed cross trip test.
Before making a final purchase decision on this DS200TCTLG1A Steam Turbine Reheat Board, it is important to understand that this DS200TCTLG1A product's A-rated functional product revision almost certainly alters its originally-introduced performance specifications and dimensions from their original base-revised state. The assembly of this DS200TCTLG1A Steam Turbine Reheat Board should be well-protected beneath a layer of normal-style PCB protective coating, which is chemically-applied to the base circuit board of this DS200TCTLG1A model and envelops and protects individual hardware elements in a thick rudimentary protective coat based on functional priority to the DS200TCTLG1A board and its greater automated drive.
