Description

The GE 531X307LTBAJG1 is a LAN I/O Terminal Board designed for GE’s 531X series drives and exciters, including the EX2000 excitation system and DC-300 drive platform.

Product Description:

The GE 531X307LTBAJG1 is a LAN I/O Terminal Board designed for GE’s 531X series drives and exciters, including the EX2000 excitation system and DC-300 drive platform. Functioning as the field-wiring interface between external control devices and the main drive controller, this board accepts a wide range of discrete input signals, converts them to standardized 24 VDC logic levels, and routes them to the control processor via ribbon cable connections.

The board serves as the primary connection point for interlocks, pushbuttons, indicator lights, and other peripheral control devices. Its hybrid I/O architecture combines high-density plug-in connectors for internal rack routing with heavy-duty screw terminals for rugged field wiring, giving retrofit and legacy systems significant flexibility in signal management.
Key Features:

  • Wide-Range Universal Inputs: Accepts 2–240 V AC/DC discrete input signals and converts them to 24 VDC logic levels compatible with the drive control board

  • 8 Configurable Control Inputs: Provides eight independent input channels via CI1PL–CI8PL onboard plugs for flexible field monitoring

  • 7 Form C Relay Outputs: Equipped with seven low-voltage, low-current Form C (SPDT) relay outputs for alarm, trip, and status signal switching

  • Onboard Diagnostics: Features 15 LED indicators (LED1–LED8 for input status, LED17–LED23 for relay output status) for rapid commissioning and troubleshooting

  • System Integration: Compatible with NTB/3TB terminal boards and routes I/O signals to the LCCBA communication board and DCCA drive controller via ribbon cables
