Product Parameter

Core Hardware and Functional Features

1. High-Horsepower (High-HP) Dedicated Design

G5 hardware revision specifically configured for high-power applications, supporting regenerative/non-regenerative drive modes with an armature voltage range of 240–630V DC .

No onboard snubbers: All buffering components are relocated to external system assemblies. This is a deliberate engineering design for Group G5—not a defect. By removing onboard snubbers and attenuation circuits, power density and heat dissipation efficiency are significantly improved for high-power SCR bridge applications .

2. SCR Power Bridge Interface

Drives high-current SCR power bridges via pulse-transformer-isolated gate signals, providing 1500V RMS galvanic isolation between low-voltage control circuits and high-voltage power sections .

12 plug connectors for forward and reverse gate pulse signals, supporting full-bridge SCR topologies .

Interfaces with DCFB-type power boards and supports Leg reactors and Leg fuses for precise branch-level overcurrent protection .

3. Flexible System Configuration

4 onboard jumpers (JP1, JP2, WP3, WP4) for configuring: card group number, system voltage range, capacitor operation, bridge timing, and voltage feedback .

Fuse-less design: relies on external Leg fuses for overcurrent protection, a design choice that simplifies board replacement and reduces maintenance time .

Compatible with J, K, and M type Mark V rack frames; supports both independent and common bus transformer configurations .

4. Diagnostics and Status Monitoring

LED indicators: PWR (Power), FAULT, TRIP—allowing quick on-site status assessment .

Board-mounted test points for signal verification (gate pulses, CT/VT feedback signals) .

5. Environmental and Reliability Design

Conformal coating for protection against dust, humidity, and chemical exposure in harsh industrial environments .

Operating temperature: -20°C to +60°C (standard industrial range) .

Low power consumption: ≤5W from backplane supply .

Multi-layer PCB design with enhanced EMI immunity .

Communication Interfacing and Protocol Compatibility

1. Supports interfacing with user microcontrollers and PLC equipment; hardware interfaces include RS-232 and RS-485 serial ports, with simultaneous compatibility for Ethernet and wireless communication methods.

2. Features built-in support for multiple communication protocols including PLC-specific protocols, Modbus, I2C, and custom protocols, ensuring broad compatibility with various on-site automation devices.

3. Monitoring and operation screens are developed using HMImaker configuration software, enabling rapid, code-free generation of graphical interfaces .

Architecture and Operational Advantages

1. Fully digital hardware design with no operating system, eliminating the risk of system crashes; the unit boots directly into the operational interface, ensuring stable display performance.

2. High electromagnetic interference (EMI) immunity, making it suitable for installation inside cabinets within high-EMI environments such as power plants and chemical processing workshops.

3. The GE Fanuc DS200PCCAG5AC offers low overall power consumption and rapid screen refresh rates; spare part replacement requires no complex low-level system installation or deployment.

4. The board performs dual functions—display and control—and serves as a critical connection point for high-power power supply systems, acting as an indispensable core component of the drive circuit.

FAQ

Q1: Can the GE Fanuc DS200PCCAG5AC be directly interchanged with a standard version PCCA card?

A: No. This model is a dedicated high-horsepower (High-HP) version with G5 hardware revision. The board itself does not integrate snubber or attenuation components—these are relocated to external system assemblies as a deliberate engineering design for high-power applications . Direct replacement with a standard version (e.g., G1/G2) will result in missing hardware and system anomalies.

Before proceeding: Verify that your system has Leg reactors and Leg fuses installed. Confirm the complete hardware configuration matches the high-power G5 requirement. If unsure, provide your system's Mark V rack serial number and we will assist with verification 

Q2: What are typical on-site symptoms when the board malfunctions?

A: Common failure symptoms include:

Unit fails to start or exhibits abnormal speed regulation

Drive unit trips with SCR bridge-related fault codes

In severe cases, immediate shutdown interlock is triggered

Important: Some failures are latent—no error alarms are displayed, and indicator lights may appear normal. These cases require comprehensive assessment based on system diagnostic data, including gate pulse signal verification and CT/VT feedback checks at board-mounted test points. Do not rely solely on LED indicators for diagnosis 

Q3: What information is required when purchasing this spare part, beyond the full model number?

A: To ensure compatibility, we recommend providing:

Mark V system version and firmware revision (if known)

Unit's power rating and armature voltage range

System rack frame type (J, K, or M)

Whether the part is for a complete unit replacement or for troubleshooting/backup purposes

Current board revision (if replacing an existing board, please provide its full model and revision)

This information helps us verify compatibility and prevent deployment failures caused by version mismatch 

Q4: What simple checks should be performed after receiving the board but before on-site installation?

A: Pre-installation checklist:

Q5: Is this circuit board still in production by the original manufacturer?

A: No. This hardware is a discontinued spare part. GE no longer mass-produces the DS200PCCAG5ACB. Market availability relies primarily on existing inventory.

Selection advice: When sourcing this part, prioritize verifying hardware version compatibility (G5 revision) and system configuration to avoid purchasing an incompatible component. We only supply genuine original boards sourced through formal channels, not refurbished or salvaged units.

Q6: Can the board be hot-swapped while the system is running?

A: No. Mark V systems were not designed for live insertion of PCCA hardware. Pulling the board under power can damage SCR interfaces or backplane connections. Always power down the system completely before removal or installation .
