It reduces high bridge voltage to a manageable level and provides attenuation between the field bus and the EGDM. The module is installed in the High Voltage Interface (HVI) module within the auxiliary cabinet.\u003c\/p\u003e\u003cp\u003eConnected via the Exciter Power Backplane (EPBP), the EXAM uses a single 9-pin cable, while EGDMs connect through a 96-pin P2 connector. This setup supports both simplex and triple modular redundant (TMR) configurations, requiring only one EXAM regardless of redundancy level.\u003c\/p\u003e\u003ch2\u003eKey Functions and Integration\u003c\/h2\u003e\u003cp\u003eThe EGDM controls a relay on the EXAM for field ground testing and master selection. This relay features a 24 V DC coil with diode suppression and operates with less than 20 mA. In default state, the relay remains de-energized, providing feedback to the M1 section (or sole control in simplex); when energized, it sends feedback to M2.\u003c\/p\u003e\u003cp\u003eIn TMR setups, three EGDMs are configured as Controller (C), Master 1 (M1), and Master 2 (M2). The DSPX board informs EGDM C which master supplies the 50 V AC square-wave signal to the sense resistor in the EXAM. This allows precise monitoring and alarming through a fiber-optic link to the EX2100E controller.\u003c\/p\u003e\u003ch2\u003eInstallation and Setup\u003c\/h2\u003e\u003cp\u003eWhen installing the \u003cstrong\u003eIS200EXAMG1AAB\u003c\/strong\u003e, ensure the board is properly seated in the HVI module.
