IS210TRELH1A is a Large Steam Turbine Emergency Trip Terminal Board manufactured and designed by General Electric as part of the Mark VI Series used in GE Speedtronic Gas Turbine Control Systems. The emergency over-speed protection for big steam turbines is provided by the Large Steam Turbine Emergency Trip (TREL) terminal board. Three emergency trip solenoids that can be attached between the TREL and TRPL terminal boards are powered by TREL, which is controlled by the VPRO in the protection module. The solenoids are supplied with the positive side of the 125 V dc by TREL and the negative side by TRPL. The I/O controller controls the nine relays on TREL, which are organized into three groups of three and connected to vote inputs that control the three trip solenoids. It also performs emergency stop functions and emergency over-speed protection. Emergency trip groups 1, 2, and 3 are the names of the three groups.
The first I/O terminal block is wired with the three trip solenoids. The second terminal block can accommodate up to seven trip interlocks. The following figure displays the wiring connections. Three power buses from TRPL are carried by connector J2, while the excitation voltage for the seven-trip interlocks is carried by connector JH1.
The only connections to the turbine control are the J2 power line and the trip solenoids. TREL is totally controlled by the VPRO protection module. When a turbine trips in simplex systems, a third cable transmits a trip signal from J1 to the TSVO terminal board, which operates a servo valve clamp.
