Description

GE DS200LRPAG1A Mark V Relay Output Board

The GE DS200LRPAG1A, also cataloged as the DS200LRPAG1A Relay Output Board, operates as a dedicated hardware component for electromechanical relay signal execution within the GE Mark V SpeedTronic turbine control system. The board converts low-level control signals into isolated field relay contact outputs for external switching circuits.

Industrial Control Backplane and Drive Interface Characteristics

The DS200LRPAG1A operates within the GE Mark V control architecture through ribbon cable header interfaces connected to the control core. Logic-level commands received from the processor section activate relay driver circuits, which energize the corresponding relay coils.

The board supports industrial control execution through electromechanical contact switching. Relay outputs provide physical isolation between control electronics and external field circuits connected to actuators, alarms, contactors, and interlock devices.

The GE Mark V hardware platform uses modular rack communication and interface cards. The DS200LRPAG1A implementation requires correct firmware and hardware revision compatibility when installed in existing control configurations.

Frequently Asked Questions

Q: Does the DS200LRPAG1A provide direct solid-state field outputs?
A: No. The board provides electromechanical relay contact outputs. The relay contacts change state after the internal relay coil is energized by the control signal interface.

Q: What diagnostic method is available for relay channel verification?
A: Each relay channel includes an LED status indicator that allows visual confirmation of relay energization during commissioning and maintenance procedures.

Q: Can the DS200LRPAG1A be installed without checking rack compatibility?
A: No. Installation requires verification of Mark V rack configuration, connector alignment, revision compatibility, and field wiring requirements before replacement or commissioning.

Field Installation Guidelines

• Verify the card rack position and connector orientation before inserting the DS200LRPAG1A module.
• Disconnect field power sources before removing or installing relay interface boards.
• Confirm ribbon cable header connections are fully seated and mechanically secured.
• Maintain separation between low-level control wiring and high-voltage field wiring to reduce electrical interference.
• Use appropriate grounding methods for the control rack and panel enclosure.
• Inspect relay contact wiring for correct polarity, load type, and external protection requirements before energizing the system.
• Confirm LED indication behavior after installation through controlled functional testing.
