Description
DS3800NTEA1C1A: Product Overview
The DS3800NTEA1C1A is a daughterboard-grade termination interface that occupies a 6BA05 slot in the GE Speedtronic Mark IV rack. It acts as the physical landing point for field cables—power, analog, and digital—while buffering, isolating, and routing those signals to the appropriate daughterboards inside the rack. The card is passive (no active silicon) and deterministic, making it suitable for safety-related signal marshalling when triple-redundant.
Physical implementation includes screw-terminal or quick-connect blocks, modular keyed connectors, 1500 V AC galvanic isolation, and TVS surge suppressors. Retention levers ensure blind-mate insertion in crowded card cages. Front-edge LEDs (green = power OK, red = field fault) give real-time wiring health—no multimeter required during commissioning.
Environmental qualification meets –20 °C to +70 °C, IEEE 344 seismic, and CE emissions, giving >20-year service life in baseload duty.

Core Features & Customer Value
High-Density Field Landing Without Active Silicon
Passive design means no firmware crashes, no latch-up, and no thermal runaway—ideal for safety-critical cable marshalling that must survive CPU reboots.

Surge-Hardened for Turbine Deck
TVS diodes clamp >500 V spikes from lightning, VFD switching, or exciter flash-over. 1500 V isolation prevents ground-fault propagation to CPU cards, reducing unplanned replacement by >60 % compared with commercial terminal blocks.

Typical Applications
Gas Turbine Field-Cable Landing
Primary termination for Frame 7/9 heavy-duty units: lands power, analog, and digital cables from turbine deck, routes them to servo, ADC, and I/O daughterboards, ensuring deterministic signal integrity during start-ups and load ramps.
