MeloAuto-Trusted PLC & DCS Parts Supplier
The GE DS200TBQGG1A DS200TBQGG1AAA gas turbine termination card connects field wiring to Mark V control system. This card provides a reliable interface between turbine sensors and the main controller. You will find this termination card in gas turbine control cabinets and auxiliary panels. Its high-density design accommodates 40 field wiring points.
Termination Architecture
This termination card provides 40 screw terminal connections for field wiring. Consequently, you can connect many sensors without additional terminal blocks. The GE DS200TBQGG1A DS200TBQGG1AAA supports both digital and analog field devices. Moreover, each terminal includes a clearly marked identification number. You can terminate wires quickly using standard slotted screwdrivers.

Field Wiring and Terminal Design
The unit uses high-quality screw clamp terminals for reliable connections. Therefore, wires stay secure even under vibration from gas turbine operation. This card replaces the DS200TBQGG1AAA version without any wiring changes. Simply remove the old card and install this one. GE designed this termination card for single-slot installation. Hence, it fits directly into existing Mark V rack positions.
Four PCB layers separate field wiring traces from backplane signals. Two connectors handle all signal and ground connections. The GE DS200TBQGG1A DS200TBQGG1AAA includes a dedicated ground bar for cable shields. Accordingly, you can terminate shield wires without additional hardware. This feature improves noise immunity in electrically noisy turbine environments.
Installation and Wiring Guide
You can terminate both stranded and solid copper wires easily. The screw clamps accept wires without special ferrules or lugs. The GE DS200TBQGG1A DS200TBQGG1AAA works with all GE Mark V I/O boards. Always strip 6-8 mm of insulation before inserting wires. Proper torque on terminal screws prevents loose connections over time.
Each terminal position corresponds directly to a specific I/O channel. The card includes four configuration jumpers for input type selection. The GE DS200TBQGG1A DS200TBQGG1AAA simplifies field wiring for gas turbine systems. Installation requires only a flathead screwdriver for terminal connections. This card operates reliably in non-condensing environments with adequate clearance.
