Product Overview

The GE DS200RTBAG3AHC is a relay terminal card used in legacy GE turbine and drive control cabinets. It provides a cabinet-level interface for relay-based switching, allowing control logic to energize relays and present their contact states to field wiring through clearly defined terminal points. This type of board is typically installed in a Mark V control/drive rack where relay outputs are used for permissives, interlocks, alarms, and device actuation.

As a terminal-style relay board, the DS200RTBAG3AHC supports maintainable panel wiring by concentrating relay contact terminations on a single assembly, reducing point-to-point wiring complexity and improving troubleshooting efficiency.

Key Technical Characteristics

• Model / Part number: DS200RTBAG3AHC

• Module category: Relay Terminal Card

• Platform association: Mark V / Speedtronic legacy control assemblies

• Relay population: 10 on-board relays for discrete switching functions

• Termination capacity: 52 field terminal points for contact and control wiring

• Contact form: includes Form C relay contacts (NO / COM / NC) on designated relays (e.g., K20 referenced in documentation sets)

• Drive method: relays can be actuated via pilot relay interfaces or cabinet control wiring depending on system design

• Replacement practice: match full part number and revision code to maintain wiring and rack compatibility

Operational Use Cases

• Discrete relay output termination for Mark V turbine control panels supporting gas, steam, or wind applications

• Alarm, trip, and permissive relay circuits requiring Form C dry-contact interfaces to plant wiring

• Retrofit maintenance where existing relay logic must be retained while replacing aging terminal assemblies

• Control cabinet refurbishments aimed at restoring reliable relay switching and stable field terminations
