IS200EXAMG1A GE Exciter Attenuation Module

IS200EXAMG1A is an Exciter Attenuation Module developed by GE under the Mark VI series. The ground detection system for the EX2100 Excitation Control is provided by the Exciter Attenuation Module IS200EXAM (EXAM) in conjunction with the Exciter Ground Detector Module IS200EGDM (EGDM). The EXAM is housed in the auxiliary cabinet's High Voltage Interface (HVI) module. It attenuates the field bus and the EGDM by sensing high voltage from the bridge and scaling it to a usable level. The Exciter Power Backplane IS200EPBP connects the EXAM and EGDM(s) (EPBP). The EXAM and the EPBP are linked by a single 9-pin cable. The EGDMs connect to the EPBP via a 96-pin connector, P2. For simplex and triple modular redundant (TMR) applications, only one EXAM is required, and the interconnection is the same.

Interfaces with both the Exciter/Regulator Options Board (EROC) and Exciter Ground Detection Module (EGDM).Facilitates field ground testing using attenuation and sense resistors to monitor for faults.Detects dead short conditions within 10 seconds, automatically shutting down the exciter to ensure system protection.Provides relay control with 24 V DC coil for activating and deactivating ground tests.Compatible with the EX2100 Excitation Control system and PGDM standalone simplex ground detector.Reliable fault detection for safe operation in industrial environments.Offers integration with Digital Signal Processor Control Boards (DSPX) for ground detection functionality.

EX2100 Excitation Control System: Interfaces with both the Exciter/Regulator Options Board (EROC) and Exciter Ground Detection Module (EGDM), depending on the model.PGDM Standalone Simplex Ground Detector: Works with interface boards like BGTB and BFGD, and a processor board BPPB for similar functionality.Digital Signal Processor Control Board (DSPX): Provides computational power for the ground detection system in the EX2100.Relay Integration: Compatible with relay activation, with 24 V DC coil for control of ground testing operations.
