GE IS200DAMAG1BCB | Mark VIe Analog Output Module In Stock

Description

Product Introduction

The GE IS200DAMAG1BCB is a Mark VIe series analog output module that delivers 8 channels of 4-20 mA control signals with a specific hardware configuration that sits between the G1B and BBA variants. This I/O pack is designed for turbine control applications requiring extended load drive capability with a particular output stage configuration that is not available in other DAMA variants.

The BCB suffix indicates a unique hardware build that combines the extended load drive of the G1B lineage with a specific DAC reference circuit and output filter configuration. In our experience, this variant was produced for specific OEM applications where the standard G1B or BBA characteristics were not optimal. The BCB’s output stage characteristics make it particularly suitable for installations with specific positioner compatibility requirements where other DAMA variants show marginal performance. For plants that have standardized on a particular valve positioner family and find the standard G1B response too aggressive or the BBA too damped, the BCB often provides the optimal solution.

Key Technical Specifications

Key Selling Points & Differentiators

• Unique hardware configuration – specific output stage and filter design not available in other DAMA variants. Essential for applications with specific positioner compatibility requirements.
• Extended load drive capability – handles up to 880 Ω loop impedance. Supports cable runs up to 500+ meters with standard positioners.
• 14-bit resolution with ±0.08% accuracy – provides precise control with a specific output response profile optimized for certain field devices.
• Rigorous 48-hour burn-in – each unit runs with all 8 channels loaded at 75% span. We verify accuracy at three points (4 mA, 12 mA, 20 mA) and test load drive to 880 Ω.
• 3-year warranty on the hardware – backed by our in-house repair depot with 48-hour average turnaround. Dedicated DAMA swap-pool ensures rapid replacement.

Frequently Asked Questions (FAQ)

Can I hot-swap this IS200DAMAG1BCB into a running Mark VIe system?

We strongly advise against it. The DAMA series has shown unpredictable behavior when inserted into a powered backplane. Schedule a controlled outage, de-energize the rack, and swap it during planned maintenance.

What is the difference between the IS200DAMAG1B, BBA, and this BCB?

The BCB has a unique output filter and DAC reference configuration. Load drive is 880 Ω (between G1B at 850 Ω and BBA at 900 Ω). The BCB’s response characteristic is different from both – it has a specific RC filter that changes the output transient behavior. In practical terms, the BCB was produced for specific OEM applications. Use the G1B for general applications, BBA for maximum performance, and BCB only if you need this specific hardware configuration for compatibility reasons.

I currently have an IS200DAMAG1B installed. Can I replace it with this BCB?

Physically, yes – same slot, same termination board. However, the BCB has different output response characteristics due to its unique filter design. Your tuning parameters may need adjustment because the BCB will respond differently to PID output changes. Plan for a 2-3 hour commissioning window to verify loop performance. In some cases, no retuning is needed; in others, significant retuning is required. We recommend having a tuning engineer available.

How do the output characteristics of the BCB differ from the G1B?

The BCB uses a different output filter that changes the rise time and settling behavior. The G1B has a faster initial response with some overshoot; the BCB has a slightly slower rise with less overshoot and better damping. This makes the BCB particularly suitable for positioners that are sensitive to step changes. The BBA is between the two. We can provide the actual step response data for your specific unit upon request.

How do I verify this is a genuine GE module and not a counterfeit?

We source exclusively from GE-authorized liquidations and maintain full traceability. Our verification includes OEM packaging inspection, serial number cross-check against GE records, PCB inspection for GE-specific markings, and functional testing. The BCB’s unique filter configuration is difficult to replicate. We provide PCB photographs upon request.

Will I lose my existing calibration data when I replace the module?

Yes – calibration constants reside in the module’s EEPROM. You will need to recalibrate each output channel. Plan for 2-3 hours of commissioning time. We can pre-load your calibration constants if you send us your old module’s data file from ToolboxST.

What is the expected lifespan of this unit?

We see MTBF around 100,000 hours for the BCB revision. Recalibration every 12 months is essential. The BCB’s specific filter components have a similar lifespan to other DAMA variants.

What happens if the module fails within the warranty period?

We cross-ship a tested replacement from our dedicated DAMA swap-pool the same business day. You return the failed unit within 15 days. Our repair depot has an average 48-hour turnaround. We test your repaired unit back to full BCB specification. You receive a BCB replacement – not a different revision.

Which termination board should I use with this module?

The IS200DAMAG1BCB mates with GE’s TS200DTA1 or TS200DTA2 termination boards. Do not use the older TS200DTA0 – it lacks proper shielding. Double-check ribbon cable orientation; pin 1 has a red stripe. We include a wiring diagram PDF with every order.
