GE IS200DAMCG1A | Mark VIe Analog Output Module In Stock

Description

Product Introduction

The GE IS200DAMCG1A is a Mark VIe series analog output module that provides 8 channels of 0-10 V voltage outputs for turbine control applications. This I/O pack is designed for field devices that accept voltage signals, such as certain variable frequency drives, servo amplifiers, chart recorders, and voltage-input positioners. It offers a dedicated voltage-only solution without the additional circuitry required for current outputs.

The DAMCG1A is the voltage-only counterpart to the DAMB series, offering a simpler design for applications that exclusively use voltage signals. The G1A revision provides improved accuracy and temperature stability over earlier DCMC variants. By eliminating the current output circuitry, this module achieves slightly lower power consumption and higher reliability in voltage-only installations. For facilities that have standardized on 0-10 V control signals, the DAMCG1A provides a cost-effective and reliable solution without paying for unused current output capability.

Key Technical Specifications

Key Selling Points & Differentiators

• Dedicated voltage-only design – optimized for 0-10 V applications with lower power consumption and simpler circuitry than dual current/voltage modules.
• 8 high-density voltage outputs – reduces cabinet space by 50% compared to older modules. Simplifies wiring for VFD and servo amplifier applications.
• 14-bit resolution with ±0.1% accuracy – provides precise voltage control for demanding applications such as servo positioning and speed control.
• Lower power consumption – draws 280 mA vs. 320-340 mA for current-output modules. Reduces backplane loading in densely populated racks.
• Rigorous 48-hour burn-in – each unit runs with all 8 channels loaded at 75% span. We verify voltage accuracy against a calibrated reference.
• 3-year warranty on hardware – backed by our in-house repair depot with average 48-hour turnaround. Dedicated DCMC swap-pool ensures rapid replacement.

Frequently Asked Questions (FAQ)

Can I hot-swap this IS200DAMCG1A into a running Mark VIe system?

We strongly advise against it. The DCMC series has shown unpredictable behavior when inserted into a powered backplane. Schedule a controlled outage, de-energize the rack, and swap it during planned maintenance.

What is the difference between the IS200DAMBG1A and the IS200DAMCG1A?

The DAMBG1A provides both current and voltage outputs. The DAMCG1A is voltage-only (0-10 V). The DCMC has lower power consumption, simpler circuitry, and is more reliable for voltage-only applications. Use DAMB if you need mixed current/voltage capability; use DCMC for voltage-only installations.

What is the minimum load impedance for voltage outputs?

The voltage outputs require a minimum load impedance of 2 kΩ. If you drive a lower impedance, the output voltage will droop and accuracy will degrade. For example, a 1 kΩ load at 10 V will draw 10 mA, which exceeds the 10 mA drive capability and will cause voltage droop. Check your field device input impedance before connecting.

Can I use this module to drive a 0-5 V input device?

The module outputs 0-10 V. You can scale the output in your application logic to provide 0-5 V by limiting the output value to 50% of range. However, resolution is reduced by half. If you frequently use 0-5 V devices, consider adding external voltage dividers for better resolution, or check if your field device accepts 0-10 V.

What happens if I short-circuit a voltage output?

The module has built-in short-circuit protection. It will limit the current to approximately 15 mA and set a fault flag in the diagnostic status. The channel will recover automatically once the short is removed. However, repeated short circuits can degrade the output protection circuitry.

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, and PCB inspection for GE-specific markings. We test voltage accuracy and load drive capability. 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, not in the controller. You will need to recalibrate each output channel against your field devices. 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 120,000 hours for the DCMC due to its simpler output stage. Recalibration every 12 months is essential. The lower power consumption also contributes to longer component life.

What happens if the module fails within the warranty period?

We cross-ship a tested replacement from our dedicated DCMC 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 G1A replacement.

Which termination board should I use with this module?

The IS200DAMCG1A mates with GE’s TS200DTC1 or TS200DTC2 termination boards. Do not use DTA-series boards (current only) or DTB-series boards (mixed). Pin assignments differ. Double-check ribbon cable orientation; pin 1 has a red stripe. We include a wiring diagram PDF with every order.
