Product Introduction

The GE is a dedicated input terminal board for the GE Mark VI Speedtronic turbine control system. This GE module connects directly to field sensors, eliminating the need for intermediate instrumentation.

Designed for high-noise environments, this GE board features built-in hardware filters to suppress high-frequency interference. It mounts securely in standard VME card racks and uses 12-pin connectors for reliable field wiring.

Key Technical Specifications

Quality Control Process

Terminal boards require meticulous electrical validation. We bench-test every GE using precision signal generators and oscilloscopes. We verify the hardware noise filters by injecting high-frequency interference and confirming signal attenuation. All 12-pin connectors are inspected for pin tension and continuity. We also inspect the PCB for thermal damage or cold solder joints. Each board ships in anti-static shielding with a traceable test report.

Replacement Pitfall Guide

❗ Hardware Filter Configurations: The J3 and J4 circuits on this GE have different filter breakpoints (500 rad/sec vs. 72/500 rad/sec). Wiring a high-speed sensor to the wrong terminal block will distort your signal.

❗ Connector Seating Force: The pluggable 12-pin terminal strips require even pressure. Never use excessive force on one side. Misaligned pins will cause intermittent faults that mimic sensor failures.

❗ VME Backplane Alignment: When inserting this board into the rack, ensure the rear connectors align perfectly with the backplane. Forcing a misaligned board can bend backplane pins and require a costly chassis replacement.

❗ Cable Shield Grounding: Since this board bypasses intermediate panels, field cable shields must be terminated correctly at the terminal board. Poor shielding turns this I/O interface into an antenna for turbine electrical noise.

Keep these in mind and you’ll cut 90% of rework time.

Compatibility Matrix & Benchmarks
