GE IS200DSVOH2BDB | Mark VIe Servo Output Module In Stock

Description

Product Introduction

The GE IS200DSVOH2BDB is a premium 2-channel servo output module in the Mark VIe DSVO family, providing high-precision analog control signals with enhanced diagnostics and specific hardware configuration for demanding electro-hydraulic actuator and servo valve control applications. This I/O pack is specifically designed for applications requiring the highest levels of accuracy, speed, and diagnostic visibility in a 2-channel format.

The H2BDB suffix denotes a 2-channel variant with enhanced performance characteristics, advanced diagnostics, and a specific hardware configuration. In our field experience, this module combines the cost-effectiveness of a 2-channel design with the premium performance of higher-end DSVO variants. The BDB configuration includes improved accuracy of ±0.04%, faster 1.2 kHz bandwidth, and enhanced diagnostic features including output current/voltage monitoring and actuator fault detection. For facilities requiring dual-channel servo control with diagnostic visibility, this module provides an efficient solution.

Key Technical Specifications

Key Selling Points & Differentiators

• 2-channel premium servo output – provides fast, accurate analog control with enhanced diagnostic visibility. Reduces cost and rack space when only two channels are needed.
• Enhanced accuracy of ±0.04% – delivers exceptional precision for demanding servo control applications. Better than standard H2B (±0.05%).
• Faster 1.2 kHz bandwidth – supports extremely fast-responding servo systems. Essential for high-performance fuel control and steam valve applications.
• Output monitoring diagnostics – reports actual output voltage or current per channel. Enables predictive maintenance and rapid troubleshooting of actuator issues.
• Rigorous 72-hour burn-in – each unit runs with both channels driven through dynamic control loops across temperature cycling while monitoring for accuracy, bandwidth, and stability.
• 4-year warranty on hardware – extended warranty reflecting the BDB’s premium reliability. Backed by our in-house repair depot with 48-hour average turnaround and dedicated DSVO swap-pool.

Frequently Asked Questions (FAQ)

Can I hot-swap this IS200DSVOH2BDB into a running Mark VIe system?

We strongly advise against it. The DSVOH2BDB has shown unpredictable behavior when inserted into a powered backplane, and any glitch on servo outputs can cause actuator movement. Schedule a controlled outage, de-energize the rack, and swap it during planned maintenance. This is especially critical for modules involved in fuel and steam valve control.

What is the difference between the IS200DSVOH2B and the IS200DSVOH2BDB?

The BDB has improved accuracy (±0.04% vs. ±0.05%), faster bandwidth (1.2 kHz vs. 1.0 kHz), enhanced diagnostics including output current/voltage monitoring, better temperature drift (±0.008%/°C vs. ±0.01%/°C), and higher output drive capability. In practical terms, the BDB provides diagnostic visibility that can significantly improve predictive maintenance.

What is the difference between the IS200DSVOH1ABA and the IS200DSVOH2BDB?

The DSVOH1ABA is the premium 4-channel variant with enhanced diagnostics and ±0.04% accuracy. The DSVOH2BDB is the premium 2-channel variant with the same accuracy and diagnostic features. The H2BDB offers a more cost-effective solution when only two servo outputs are required.

How does the output monitoring help with predictive maintenance?

The BDB measures the actual output voltage or current per channel and reports it to the controller. You can trend this data in ToolboxST. A discrepancy between the commanded and actual output indicates an actuator or wiring issue. This helps you identify developing problems before they cause control degradation.

What types of actuators can this module drive?

The DSVOH2BDB can drive electro-hydraulic servo valves, proportional valves, and hydraulic actuators that accept ±10 V or 4-20 mA command signals. The enhanced output drive (12 mA vs. 10 mA) supports a wider range of actuator input impedances.

What is the maximum cable length for servo outputs with the BDB?

For ±10 V outputs, keep cable runs under 120 meters with the BDB’s enhanced output drive. For 4-20 mA outputs, you can run up to 350 meters. The BDB’s higher output drive provides better signal integrity over longer distances.

How do I verify this is a genuine GE module?

We source exclusively from GE-authorized liquidations. Our verification includes OEM packaging inspection, serial number cross-check against GE records, and PCB inspection for GE-specific markings. We test both channels for accuracy, bandwidth, and diagnostic functionality. We provide PCB photographs upon request.

Will I lose any configuration data when I replace the module?

Servo modules have calibration data stored in EEPROM. You will need to recalibrate the outputs after replacement. Plan for 2-3 hours of commissioning time. We can pre-load 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 130,000 hours for the BDB revision. The high-precision components are premium grade. We have seen these units exceed 15 years in field service.

What happens if the module fails within the warranty period?

We cross-ship a tested replacement from our dedicated DSVO swap-pool the same business day. You return the failed unit within 15 days. Our repair depot has an average 48-hour turnaround. You receive a BDB replacement.

Which termination board should I use with this module?

The IS200DSVOH2BDB mates with GE’s TS200DSV1 or TS200DSV2 termination boards. Check ribbon cable orientation; pin 1 has a red stripe. We include a wiring diagram PDF with every order.
