I/O modules

Product Overview

The GE DS200TCDAH1BGD is a Digital I/O Board designed for the Mark V Speedtronic turbine control system. It manages relay outputs and contact inputs while integrating seamlessly with other boards, such as STCA, UCPB, TCQA, and TCQE. This board ensures precise turbine control and supports ongoing maintenance of legacy Mark V systems.

Hardware Configuration

The DS200TCDAH1BGD includes jumpers, connectors, and configurable input/output interfaces:

Jumpers:

• J1-J3: General configuration settings
• J4-J6: Reserved for IONET addressing, remain at factory settings
• J7: Enables stall timer
• J8: Activates test mode

Connectors:

• JP: TCPS board power signal connector
• JQ: DTBA contact input signals connector
• JR: DTBB contact input signals connector
• JO1: TCRA contact output signals connector
• JX1 & JX2: Daisy-chained IONET network connectors

This labeling system guarantees correct connections and functional integration within Mark V turbine setups.

Installation and Assembly

The DS200TCDAH1BGD installs at the R1 core of the Mark V cabinet. GE designed it for standard assembly and backward compatibility across three revisions. The board works directly with other Mark V modules to maintain accurate control logic and system coordination.
