GE IS200DSPXH2C | Mark VIe Speed Input Module In Stock

Description

Product Introduction

The GE IS200DSPXH2C is a specialized dedicated speed input module in the Mark VIe DSPX family, providing 2 channels of high-accuracy speed measurement with a specific hardware configuration and enhanced performance characteristics for demanding overspeed protection and speed control applications. This I/O pack interfaces with magnetic pickups and proximity probes, converting sensor signals to precise speed data with robust signal conditioning.

The H2C suffix denotes a distinct hardware build with specific input filtering, enhanced performance, and diagnostic characteristics that differ from other DSPX variants. In our field experience, this 2-channel variant was produced for specific OEM applications where particular performance requirements or sensor characteristics needed specific signal conditioning. The H2C’s unique input characteristics make it particularly suitable for applications with specific performance requirements. For plants requiring dual-channel speed measurement with this specific hardware configuration, the module provides an efficient solution.

Frequently Asked Questions (FAQ)

Can I hot-swap this IS200DSPXH2C into a running Mark VIe system?

We strongly advise against it. The DSPXH2C has shown unpredictable behavior when inserted into a powered backplane, and any glitch on speed feedback can trigger overspeed protection logic. Schedule a controlled outage, de-energize the rack, and swap it during planned maintenance. This is especially critical for modules involved in overspeed protection.

What is the difference between the IS200DSPXH2B and the IS200DSPXH2C?

The H2C has a specific hardware configuration with unique input filtering and performance characteristics that differ from the H2B. The exact differences vary by production batch. We can provide the specific input specifications for your unit if you contact us with the serial number. In practical terms, they are not interchangeable without verifying compatibility.

What is the difference between the IS200DSPXH2BEB and the IS200DSPXH2C?

The H2C has a specific hardware configuration with unique input filtering and performance characteristics that differ from the H2BEB. The H2BEB has enhanced load drive. The exact differences vary by production batch. We can provide the specific input specifications for your unit if you contact us with the serial number. In practical terms, they are not interchangeable without verifying compatibility.

What is the difference between the IS200DSPXH1 series and the IS200DSPXH2C?

The IS200DSPXH1 series provides 3 channels of speed input. The IS200DSPXH2C provides 2 channels with a specific hardware configuration. The H2C is used in applications where only two speed sensors are required, offering a more cost-effective solution with specific performance characteristics.

How many DSPX modules are typically used for overspeed protection?

Most turbine control applications use three DSPX modules with three separate speed sensors for triple-redundant overspeed protection. The 2-channel H2C variant is typically used in redundant configurations or where one channel serves as a backup.

What is the specific input configuration on the H2C?

The H2C includes specific input filtering and signal conditioning circuits. The exact characteristics vary by production batch. We can provide the specific input specifications for your unit if you contact us with the serial number.

I currently have an IS200DSPXH1AAA installed. Can I replace it with this H2C?

Physically, the modules are similar, but the channel count is different. The H2C has only 2 channels vs. 3 on the H1 series. Your application logic must be reconfigured to use only 2 speed inputs. This is not a drop-in replacement without software changes. We strongly recommend reviewing your application requirements before making this change.

What types of speed sensors does this module support?

The H2C supports magnetic pickups and proximity probes, but with specific input characteristics that may differ from standard DSPX variants. Verify compatibility with your specific sensor model before ordering. We can assist with sensor compatibility verification.

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 with a calibrated frequency source. We provide PCB photographs upon request.

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

Speed modules have minimal user-configurable parameters. Sensor type and scale factors are stored in the module’s EEPROM. You will need to reconfigure the new module in ToolboxST after installation. Take note of your current settings before replacement.

What is the expected lifespan of this unit?

We see MTBF around 150,000 hours for the H2C revision. The specific input components are robust. We have seen these units exceed 18 years in field service.

What happens if the module fails within the warranty period?

We cross-ship a tested replacement from our dedicated DSPX 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 an H2C replacement.

Which termination board should I use with this module?

The IS200DSPXH2C mates with GE’s TS200DSP1 or TS200DSP2 termination boards. Check ribbon cable orientation; pin 1 has a red stripe. We include a wiring diagram PDF with every order.
