Energy Storage and Noise Filtering Performance
The GE IS200TTURH1C IS200TTURH1CAA stores sufficient energy for signal conditioning. Its twelve capacitors provide 1,200 µF of total capacitance. This storage filters high-frequency noise from field wiring. Furthermore, the suppression diodes clamp voltage spikes at 30 VDC, protecting the main rack electronics.
Role Within the Mark VI Speedtronic System
You will typically find the GE IS200TTURH1C IS200TTURH1CAA mounted near the turbine control panel. It connects to the main rack via three shielded ribbon cables. Moreover, this board supports both analog and digital signal types. Its twenty terminal blocks accept wiring from speed probes, LVDTs, thermocouples, and contact outputs.
Installation and Wiring Guidelines
Use the GE IS200TTURH1C IS200TTURH1CAA as a direct replacement for older TTUR revisions. Always disconnect field power before terminating any wires. This terminal board requires no external power supply for passive signal paths. It needs no configuration jumpers or special tools. Simply secure the board with four mounting screws and connect your field cables to the appropriate terminal blocks.
