Description   Product Introduction The GE IS200DRTDH1A is a Mark VIe series digital output module that provides 16 channels of solid-state DC outputs for switching field devices in gas and steam turbine control applications. This I/O pack interfaces with DC solenoids, indicator lights, solid-state relays, and other discrete field devices requiring high-speed DC switching. It serves as the solid-state counterpart to the relay output DRLYH series, offering faster response and maintenance-free operation. The H1A revision provides 16 channels of 24 V DC high-side driver outputs, each rated for 0.5 A with built-in short-circuit and over-temperature protection. The module includes per-channel status LEDs for immediate visual feedback of output states. In our field experience, the DRTDH series is preferred for applications requiring fast cycling (e.g., high-speed valve sequencing, purge cycles) where mechanical relay wear and contact bounce are unacceptable. For facilities needing high-speed, maintenance-free DC outputs, the DRTDH series provides a reliable solid-state solution.   Key Technical Specifications Parameter Value Model Number IS200DRTDH1A Series Mark VIe IS200 Hardware Revision H1A Number of Outputs 16 digital output channels Output Type High-side driver (solid-state) Output Voltage 24 V DC nominal Output Current 0.5 A per channel (continuous) Short-Circuit Protection Yes, current limit at 0.8 A typical Over-Temperature Protection Yes, thermal shutdown with auto-recovery Response Time <1 ms (ON and OFF) Diagnostics Output state feedback, short-circuit detection, over-temperature detection 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, 250 mA typical Bus Interface VME-based high-speed parallel bus Firmware Verify compatibility with ToolboxST/ToolboxEX versions ≥6.0 Termination Board Compatibility TS200DRT1, TS200DRT2 LED Indicators Per-channel output state, power, module fault, fault indication Leakage Current <100 µA when OFF   Key Selling Points & Differentiators 16 channels of solid-state DC outputs – maintenance-free switching with no mechanical contacts to wear out. Handles high-speed cycling with no contact bounce. Short-circuit and over-temperature protection – each output is protected against faults. If a short occurs, the output current limits and the channel will not be damaged. <1 ms response time – significantly faster than relay outputs (10 ms). Essential for high-speed valve sequencing and fast control applications. Per-channel status LEDs with fault indication – each output has a dedicated LED. Fault conditions (short circuit, over-temperature) are indicated by a separate fault LED. Rigorous 48-hour burn-in – each unit runs with all 16 channels toggled at 1 kHz with 50% duty cycle while monitoring for output errors and thermal issues. 3-year warranty on hardware – backed by our in-house repair depot with average 48-hour turnaround. Dedicated DRTDH swap-pool ensures rapid replacement.   Frequently Asked Questions (FAQ) Can I hot-swap this IS200DRTDH1A into a running Mark VIe system? We strongly advise against it. The DRTDH series has shown unpredictable behavior when inserted into a powered backplane due to transient currents during power-up. Schedule a controlled outage, de-energize the rack, and swap it during planned maintenance. What is the maximum current per output? Each output is rated for 0.5 A continuous at 24 V DC. The short-circuit protection limits at approximately 0.8 A. For loads above 0.5 A, you need to add an external relay or contactor. Do not parallel outputs to increase current rating. What type of loads can I drive with this module? The DRTDH drives resistive, inductive, and capacitive DC loads up to 0.5 A. For inductive loads (solenoids, relays), the module includes internal freewheeling diodes to protect against back EMF. For lamp loads (incandescent), the inrush current can exceed 0.5 A – use a relay output module or external derating. What is the difference between the DRTDH and the DRLYH series? The DRTDH uses solid-state high-side drivers with 0.5 A capacity and <1 ms response. The DRLYH uses mechanical relays with 2 A capacity and 10 ms response. Use DRTDH for fast switching and maintenance-free operation; use DRLYH for higher current and AC loads. Can I drive 120 V DC loads with this module? No. The DRTDH is designed for 24 V DC loads only. Using higher voltage will damage the output drivers. If you have 120 V DC loads, consider an external interposing relay or a different module. What happens if an output short-circuits? The output will limit current to approximately 0.8 A and the over-temperature protection will shut down the channel after a few seconds if the short persists. The channel will auto-recover once the short is removed and the channel cools. This prevents damage to the module. 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 16 outputs for current capability and protection functionality. We provide PCB photographs upon request. Will I lose any configuration data when I replace the module? Digital output modules have no user-configurable parameters stored locally. Once you install the replacement module, the controller will recognize it and resume controlling the outputs. No calibration or configuration is required. What is the expected lifespan of this unit? We see MTBF around 150,000 hours for the DRTDH series. There are no mechanical contacts to wear out. The output drivers have a virtually infinite life under normal operating conditions. We have seen these modules exceed 20 years in field service. What happens if the module fails within the warranty period? We cross-ship a tested replacement from our dedicated DRTDH 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 DRTDH replacement. Which termination board should I use with this module? The IS200DRTDH1A mates with GE’s TS200DRT1 or TS200DRT2 termination boards. Check ribbon cable orientation; pin 1 has a red stripe. We include a wiring diagram PDF with every order.
