Description
Product Introduction
The GE IS200CABPG1A functions as the Cabinet Bus Power (CABP) module within the Mark VIe control platform, providing regulated power distribution to I/O modules within a Mark VIe cabinet. This module interfaces with the Mark VIe controller via ISBus communication and distributes 24 V DC power to up to 8 I/O modules with comprehensive protection and monitoring.
The model number breaks down as: IS200 (Mark VIe platform), CABP (Cabinet Bus Power), G1 (Generation 1), A (Enhanced Configuration). The primary differentiator is the combination of regulated power distribution and diagnostic monitoring—the CABP provides reliable power distribution with per-channel status monitoring and fault detection.

Key Selling Points & Differentiators
- Regulated Power Distribution: Provides stable 24 V DC power to I/O modules—ensures reliable operation of field devices.
- Compact Design: 8 output channels in a compact module—efficient use of cabinet space.
- Comprehensive Protection: Short-circuit and overcurrent protection on each output—prevents faults from affecting other modules.
- Diagnostic Monitoring: Per-channel status and fault detection via ISBus—enables remote monitoring and rapid fault identification.
- Auto-Reset Protection: Outputs automatically reset after a fault clears—reduces downtime.
- Full Live Test Certification: Each unit undergoes a 24-hour burn-in with full load testing, protection verification, and ISBus communication testing. We log the MAC ID and calibration data for traceability.
- Direct Drop-In Replacement: Form-fit-function compatible with IS200CABPG1 and earlier CABP revisions. Existing wiring and terminal assignments remain unchanged.
- 90-Day Warranty: Includes technical support and cross-ship replacement within 24 hours if the module fails to provide power distribution, protection circuits fail, or diagnostics report false faults.
Frequently Asked Questions (FAQ)
Q1: What’s the difference between the IS200CABPG1A and the DS2020UPLAG1A?
The CABP is a power distribution module that distributes 24 V DC power to I/O modules within a cabinet. The UPL is a power distribution module that also provides ISBus communication pass-through. The CABP is for power distribution only (no communication). The UPL combines power distribution with ISBus communication. The CABP is typically used in smaller configurations where ISBus communication is handled by other modules.
Q2: What’s the maximum total current I can draw from the CABP?
The CABP has a total capacity of 5 A continuous. This is the sum of all output channels. For example, if you have 8 outputs, each can draw up to 0.625 A on average, but the total must not exceed 5 A. The module includes over-temperature protection that will trip if the total load exceeds 5 A for more than 10 seconds.
Q3: The CABP shows a fault on channel 3—what could be the cause?
A fault on channel 3 indicates that the output has tripped due to: (1) Short circuit—the output is shorted to ground or 24 V, (2) Overcurrent—the load is drawing more than the channel’s capacity, (3) Over-temperature—the module has exceeded its thermal limit. Access the diagnostic data in ToolboxST to identify the specific condition. The output will attempt to auto-reset after the fault is cleared. Investigate the load and wiring on that channel.
Q4: Can I use the CABP with both AC and DC inputs?
The CABP is designed for 24 V DC input only. It does not accept AC input. For AC to DC conversion, use a UPSA module (which accepts AC or DC input and provides 24 V DC output). The CABP is designed to distribute 24 V DC power from a UPSA, UPL, or external 24 V DC supply.
Q5: What’s the maximum cable length for the outputs?
For 24 V DC outputs, the maximum cable length is limited by voltage drop. With 1.5 mm² cable and 0.5 A load, you can run up to 150 meters before voltage drop exceeds 5% (1.2 V). For longer runs, use a larger cable gauge. The CABP’s outputs are protected against short circuits, but voltage drop will affect the voltage at the load.
Q6: The CABP shows an over-temperature warning—what should I do?
An over-temperature warning indicates that the module’s internal temperature is approaching the limit. Check: (1) Cabinet ventilation—ensure there is adequate airflow, (2) Load—reduce the load if possible, (3) Ambient temperature—ensure the cabinet is not exceeding 60°C. The module will trip if the temperature exceeds the limit. Add cooling or reduce load.
Q7: What’s the typical lead time for the IS200CABPG1A, and do you recommend stocking spares?
The IS200CABPG1A is a commonly stocked module—we maintain 8-12 units in inventory. Standard lead time for orders of 1-10 units is 1-2 business days for shipping after QC verification. For critical power distribution applications, we recommend stocking one spare CABP per cabinet. If you have a fleet of 10+ turbines, a 10% spare ratio is standard practice.
