- Description Product Introduction The GE IS200DAMDG2A is a Mark VIe series analog output module providing 8 channels of isolated 4-20 mA outputs with enhanced load drive and diagnostic features. This I/O pack is designed for demanding actuator and valve control applications where channel isolation and extended load drive are essential for reliable turbine operation. It serves as an upgraded alternative to the DAMDG1A with improved diagnostic capabilities. The G2A revision builds upon the G1A with enhanced diagnostic features, including load impedance monitoring and output current verification. In our field experience, the DAMDG2A provides the same 850 Ω load drive and per-channel isolation as the G1A, but adds real-time load monitoring that enables predictive maintenance and faster troubleshooting. The G2A’s additional diagnostic visibility can significantly reduce downtime when control loops begin to show instability. Key Technical Specifications Parameter Value Model Number IS200DAMDG2A Series Mark VIe IS200 Hardware Revision G2A (enhanced diagnostics) Number of Outputs 8 analog output channels Output Range 4-20 mA (software configurable per channel) Resolution 14-bit DAC (0.006% of span) Accuracy ±0.1% of span at 25°C (calibration required every 12 months) Drift ±0.025% per °C typical Load Impedance 0-850 Ω (maximum) Isolation 500 V DC channel-to-channel, 500 V DC channel-to-backplane Diagnostics Open-loop detection, short-circuit protection, load impedance monitoring, output current verification Load Monitoring Reports actual loop impedance per channel to controller Operating Temperature −30°C to 65°C (ambient, with 0.5 m/s airflow) Power Supply 24 V DC ±10% from backplane, 335 mA typical Bus Interface VME-based high-speed parallel bus Firmware Requires ToolboxST/ToolboxEX version 6.2 or higher Termination Board Compatibility TS200DTD1, TS200DTD2 (check ribbon cable orientation) Response Time <10 ms to 90% of final value Key Selling Points & Differentiators 850 Ω load drive capability – supports cable runs up to 500 meters with standard positioners. Critical for large turbine installations with distributed field devices. Per-channel isolation – eliminates ground loops and common-mode noise issues. Essential for plants with complex grounding or high-EMI environments. Diagnostics with load impedance monitoring – reports actual loop impedance per channel. Enables predictive maintenance and rapid troubleshooting. Field technicians can isolate wiring issues without meters. 8 high-density outputs – reduces cabinet space by 50% compared to older modules. Cuts I/O rack count and simplifies wiring. Rigorous 48-hour burn-in – each unit runs with all 8 channels loaded at 75% span. We test each channel against a calibrated reference resistor and verify load drive to 850 Ω. 3-year warranty on hardware – backed by our in-house repair depot with average 48-hour turnaround. Dedicated DAMDG2A swap-pool ensures rapid replacement. Frequently Asked Questions (FAQ) Can I hot-swap this IS200DAMDG2A into a running Mark VIe system? We strongly advise against it. The DAMDG2A series has shown unpredictable behavior when inserted into a powered backplane, and the isolation circuitry makes it particularly sensitive. Schedule a controlled outage, de-energize the rack, and swap it during planned maintenance. What is the difference between the IS200DAMDG1A and the IS200DAMDG2A? The DAMDG2A adds enhanced diagnostics including load impedance monitoring and output current verification. The G2A also requires ToolboxST 6.2 or higher to access the diagnostic data. The load drive and isolation specifications are identical (850 Ω, 500 V). Choose the G2A if you want diagnostic visibility; choose the G1A if diagnostics are not required. What is the difference between the IS200DAMAG1A and the IS200DAMDG2A? The DAMAG1A is a standard 4-20 mA output with 750 Ω load drive and no per-channel isolation. The DAMDG2A provides higher load drive (850 Ω), per-channel isolation, and diagnostics. Use the DAMDG2A for long cable runs, challenging grounding conditions, or where diagnostic visibility is needed. How do the load impedance diagnostics work? The DAMDG2A measures the total loop impedance (cable field device) and reports it to the controller through diagnostic registers. A sudden change in impedance indicates a wiring problem – loose connection, corrosion, or failing positioner. You can trend this data in ToolboxST. We include a quick-reference guide for interpreting impedance values. 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 isolation resistance (>10 MΩ) and load drive to 850 Ω. 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 DAMDG2A. The additional diagnostic circuitry adds slight complexity. Recalibration every 12 months is essential. What happens if the module fails within the warranty period? We cross-ship a tested replacement from our dedicated DAMDG2A swap-pool the same business day. You return the failed unit within 15 days. Our repair depot has an average 48-hour turnaround. No restocking fees. You receive a DAMDG2A replacement. Which termination board should I use with this module? The IS200DAMDG2A mates with GE’s TS200DTD1 or TS200DTD2 termination boards. Do not use DTA-series boards. Pin assignments differ. Double-check ribbon cable orientation; pin 1 has a red stripe.
