FUNCTIONAL DESCRIPTION:
IS210TTSAG1A is a Trip Solenoid Interface Terminal Board manufactured and designed by General Electric as part of the Mark VI Series used in GE Speedtronic Gas Turbine Control Systems. The Trip Solenoid Interface Terminal board (TTSA) provides four sets of power resistors in a configuration to support bipolar currents in trip solenoids. All connections to the board are made through pluggable barrier terminal strips. The board is the functional equivalent of the 194B5725 Servo Module in a smaller physical design. Power ratings are adequate to withstand a high DC line of 145v DC and zero solenoid impedance.
INSTALLATION:
Up to four trip solenoid coils are wired through TTSA to provide a bipolar coil current. All connections are made through the barrier terminal strips to the appropriate tripping board and solenoid coils.
OPERATION:
Fixed 125 V nominal DC power is applied to terminals 11 (positive) and 02 (negative). With no other power, a trip current is applied to the external solenoid coil pair with a magnitude equal to 1⁄2 VDC / (10k + parallel solenoid impedance). If a 1 Ω solenoid coil is used and VDC is 125 V the current in each coil equals 1⁄2 * 125 / (10,000 + 500) = 5.95 mA. When running current is desired in the solenoid coils positive DC is applied to the TS#-POS terminal and negative DC is applied to the TS#-NEG terminal. This causes a reverse current in the coil with a magnitude equal to [1⁄2 VDC / (4.4k + parallel solenoid impedance)] trip current. For the previous example this equals [1⁄2 * 125 / (4,400 + 500)] – 5.95 mA = 6.8 mA

What is a Trip Solenoid Interface Terminal Board?
A Trip Solenoid Interface Terminal Board is a crucial component in turbine control systems and other industrial applications. It serves as a centralized platform for connecting, controlling, and monitoring trip solenoids, which are essential for initiating emergency shutdowns.
How does a Trip Solenoid Interface Terminal Board improve system safety?
The board enhances system safety by providing reliable control over trip solenoids, which are crucial for emergency shutdowns. It ensures that the solenoids receive accurate signals to activate in case of a fault or hazardous condition, thereby preventing potential damage to equipment and ensuring the safety of personnel.
What is the role of LEDs on the Trip Solenoid Interface Terminal Board?
LEDs provide visual indicators of the status of each connection and solenoid. They help operators quickly identify which solenoids are active, if there are any faults and the overall operational status of the board.
