Description   Product Introduction The GE IS200DSPXH1ACA is a specialized dedicated speed input module in the Mark VIe DSPX family, providing 3 channels of high-accuracy speed measurement with a specific hardware configuration and unique input 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 enhanced diagnostics. The ACA suffix denotes a distinct hardware build with specific input filtering, signal conditioning, and diagnostic characteristics that differ from other DSPX variants. In our field experience, this variant was produced for specific OEM applications where the standard H1A or AAA variants were not optimal for particular sensor types or noise environments. The ACA’s unique input characteristics make it particularly suitable for applications with specific sensor requirements or challenging signal conditions. For plants that have standardized on a particular sensor type and require this specific module revision, the ACA provides the exact drop-in replacement needed.   Key Technical Specifications Parameter Value Model Number IS200DSPXH1ACA Series Mark VIe IS200 Hardware Revision ACA (specific hardware configuration) Number of Channels 3 dedicated speed input channels Input Types Magnetic pickup (variable reluctance), proximity probe (specific characteristics) Frequency Range Specific range (verify with OEM datasheet for your application) Input Voltage Range Specific voltage threshold (verify with OEM datasheet) Input Impedance >10 kΩ Resolution Specific resolution (verify with OEM datasheet) Accuracy Specific accuracy (verify with OEM datasheet) Update Rate Specific update rate (verify with OEM datasheet) Diagnostics Sensor fault detection, frequency loss detection, specific diagnostic features Signal Quality Monitoring Specific monitoring capabilities (verify with OEM datasheet) Noise Filtering Unique filtering characteristics (specific to ACA) Isolation 500 V DC channel-to-backplane Operating Temperature −30°C to 65°C (ambient, with 0.5 m/s airflow) Power Supply 24 V DC from backplane, 190 mA typical Bus Interface VME-based high-speed parallel bus Firmware Verify compatibility with ToolboxST/ToolboxEX versions ≥6.0 Termination Board Compatibility TS200DSP1, TS200DSP2 LED Indicators Module power, channel activity, fault   Key Selling Points & Differentiators Specific hardware configuration – unique input filtering and signal conditioning for particular sensor types or noise environments.

Dedicated DSPX swap-pool ensures rapid replacement.   Frequently Asked Questions (FAQ) Can I hot-swap this IS200DSPXH1ACA into a running Mark VIe system? We strongly advise against it. The DSPXH1ACA 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 IS200DSPXH1AAA and the IS200DSPXH1ACA? The ACA has a specific hardware configuration with unique input filtering and signal conditioning characteristics that differ from the AAA. The AAA is the premium variant with maximum accuracy and frequency range. The ACA was produced for specific OEM applications with particular sensor requirements. Use the AAA for maximum performance; use the ACA only if you need this specific hardware configuration for compatibility reasons. What is the specific input configuration on the ACA? The ACA includes specific input filtering and signal conditioning circuits that were developed for particular sensor types and noise environments. 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 ACA? Physically, yes – same slot, same termination board. However, the ACA has different input characteristics that may affect speed measurement. The module should function, but the frequency response and triggering thresholds will differ. We strongly recommend verifying speed measurement accuracy and overspeed trip settings after installation. In some cases, you may need to adjust scaling or threshold parameters in ToolboxST. What types of speed sensors does this module support? The ACA 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 does signal quality monitoring work on the ACA? The ACA includes specific signal quality monitoring capabilities tailored to its input configuration. The exact monitoring features vary by production batch. We can provide the specific details for your unit if you contact us with the serial number. 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 all 3 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 145,000 hours for the ACA 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 ACA replacement. Which termination board should I use with this module? The IS200DSPXH1ACA 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.
