GE 750-P5-G5-D5-HI-A20-R Analog Output Module | Mark VIe Distributed Control System
Engineering Background
The GE 750-P5-G5-D5-HI-A20-R is a high-integrity analog output module designed for GE’s Mark VIe Distributed Control System (DCS) platform — the industry-standard turbine and power plant control architecture deployed across gas turbines, steam turbines, combined-cycle plants, and critical process industries worldwide. Built to GE’s stringent reliability specifications, this module delivers precision 4–20 mA analog output signals with full channel isolation, making it the preferred choice for demanding continuous-process control loops.
Product Positioning
Engineered for procurement engineers and control system integrators who require a verified, drop-in replacement or expansion module for existing Mark VIe installations. The 750-P5-G5-D5-HI-A20-R eliminates compatibility risk and reduces commissioning time by maintaining full backward compatibility with GE’s Mark VIe I/O architecture.

Engineering Advantages
- High-Integrity Isolation: Each output channel is individually isolated, eliminating ground loop interference and protecting field instrumentation from cross-channel faults.
- Precision Signal Fidelity: 4–20 mA output maintains accuracy across full cable runs, critical for valve positioners, variable-speed drives, and transmitter setpoints.
- Mark VIe Native Compatibility: Plug-and-play integration with existing Mark VIe I/O racks — no firmware patching or hardware modification required.
- Redundancy Support: Compatible with Mark VIe TMR (Triple Modular Redundancy) and simplex configurations.
- Reduced MTTR: Hot-swap capable within Mark VIe architecture, minimizing plant downtime during module replacement.
- Long Service Life: GE industrial-grade components rated for continuous 24/7 operation in harsh plant environments.
System Architecture & Signal Flow
The 750-P5-G5-D5-HI-A20-R interfaces directly with the Mark VIe I/O pack via the IONet Ethernet backbone. The controller issues setpoint commands over IONet; the module converts digital setpoints to precision 4–20 mA analog signals delivered to field devices (control valves, actuators, VFDs). Each channel’s isolated output prevents common-mode noise from propagating across the control loop, ensuring signal integrity in electrically noisy plant environments.
Signal path: Mark VIe Controller → IONet → 750-P5-G5-D5-HI-A20-R AO Module → Terminal Board → Field Device (4–20 mA)

Technical FAQ
Q: Is the 750-P5-G5-D5-HI-A20-R compatible with Mark VI (non-VIe) systems?
A: No. The Mark VIe IONet architecture is not backward compatible with Mark VI IONET. Confirm your controller generation before ordering.
Q: How many analog output channels does this module provide?
A: Channel count is defined by the I/O pack configuration. Please contact us with your terminal board part number for exact channel mapping confirmation.
Q: Can this module be used in a TMR (Triple Modular Redundancy) configuration?
A: Yes. The 750-P5-G5-D5-HI-A20-R is compatible with Mark VIe TMR I/O pack configurations when paired with the appropriate terminal board.
Q: What is the lead time for this part?
A: In-stock units ship within 2–5 business days. For large quantity orders, contact us for availability confirmation.
Q: Do you provide a warranty?
A: Yes. All modules carry a 90-day functional warranty. Extended warranty options are available upon request.
