Description
Product Introduction
The GE IS200CABPG1B functions as the Cabinet Bus Power (CABP) module within the Mark VIe control platform, providing extended temperature range for 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 in extreme conditions.
The model number breaks down as: IS200 (Mark VIe platform), CABP (Cabinet Bus Power), G1B (Extended Temperature Range -40 to +70°C). The primary differentiator is the combination of regulated power distribution and extended temperature range—the CABP G1B provides reliable power distribution for outdoor, offshore, and extreme climate turbine installations.

Key Selling Points & Differentiators
- Extended Temperature Range: -40 to +70°C operation—designed for outdoor, offshore, arctic, and extreme climate installations.
- 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.
- Gold-Plated Terminals: Corrosion-resistant contacts for reliable connections in harsh environments.
- Full Live Test Certification: Each unit undergoes a 72-hour burn-in with temperature cycling (-40 to +70°C, five cycles), full load testing, protection verification, and ISBus communication testing. We log the MAC ID, calibration data, thermal cycling data, and diagnostic baselines for complete traceability.
- Direct Drop-In Replacement: Form-fit-function compatible with IS200CABPG1A 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, diagnostics report false faults, or temperature specifications are not met.
Frequently Asked Questions (FAQ)
Q1: What’s the difference between the IS200CABPG1B and the IS200CABPG1A?
The G1B variant has extended temperature range (-40 to +70°C) and gold-plated terminals. The G1A variant is standard temperature (-25 to +60°C) without gold-plated terminals. Functionally, both modules provide the same power distribution capability. Choose the G1B for harsh environments—outdoor, offshore, arctic, or extreme climate installations. Choose the G1A for indoor, climate-controlled applications.
Q2: What applications are best suited for the CABP G1B?
The CABP G1B is ideal for: (1) Outdoor turbine control cabinets in cold or extreme climates, (2) Offshore platforms where temperature extremes and moisture are concerns, (3) Desert installations with high ambient temperatures, (4) Remote locations where module replacement is difficult, (5) Any power distribution application requiring maximum environmental robustness.
Q3: The CABP shows a temperature warning at 55°C ambient—is that normal?
A temperature warning at 55°C ambient is expected—the module’s thermal warning triggers at 80°C internal. At 55°C ambient, the internal temperature could be 65-70°C, so a warning is plausible. The module will continue to operate normally—the warning is a heads-up to check cabinet cooling. The extended-temperature components are rated for 70°C ambient, so the module is within specification. The module will not derate until internal temperature exceeds 95°C.
Q4: 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.
Q5: 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.
Q6: 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.
Q7: What’s the typical lead time for the IS200CABPG1B, and do you recommend stocking spares?
The IS200CABPG1B is a specialized, moderate-volume module—we maintain 3-5 units in inventory. Standard lead time for orders of 1-3 units is 4-6 weeks due to the specialized extended-temperature component sourcing, thermal cycling validation, and calibration. For critical power distribution applications in harsh environments, we strongly recommend stocking one spare module per site. If you have a fleet of 5+ turbines, a 20% spare ratio is standard practice. If you need immediate delivery and the G1B variant is out of stock, consider the G1A variant as a temporary substitute—it provides the same functionality but lacks the extended temperature range.
