Core Monitoring Function for Power Generation
The GE IS200TGENH1A is a Generator Monitor (TGEN) terminal board for the Mark VI and Mark VIe Speedtronic control systems . This module interfaces directly with the VGEN processor to monitor three-phase generator voltages and currents . It calculates essential parameters like real power, reactive power, apparent power, and power factor . Consequently, this terminal board provides the critical electrical data needed for safe and efficient generator operation.
Comprehensive Input Configuration and Protection
The IS200TGENH1A accepts two three-phase PT inputs and three single-phase CT inputs, each with magnetic isolation up to 1500 V RMS . It also includes four configurable analog inputs that support 4-20 mA, ±5 V DC, and ±10 V DC signals . The CT terminations feature non-pluggable terminal blocks with captive lugs to prevent open circuit conditions . Furthermore, this board includes surge suppression, noise filtering, and self-diagnostics for robust system reliability .
Technical Specifications and Physical Attributes
Engineers designed this module for seamless integration into Mark VI VME racks and cabinets. It communicates with the VGEN processor via 37-pin D-Sub cables and supports both simplex and TMR applications . The following table details its key physical and functional parameters.
