- Description Product Introduction The GE IS200DAMEG1A is a Mark VIe series analog output module that delivers 16 channels of 4-20 mA control signals in a single I/O pack, making it the highest-density analog output module in the Mark VIe lineup. This module is designed for turbine control applications requiring a large number of analog outputs in limited rack space, such as combined-cycle plants with multiple actuators, complex steam temperature control systems, and facilities with extensive valve and positioner networks. The G1A revision provides 16 channels of 14-bit resolution output with ±0.1% accuracy and 750 Ω load drive. By doubling the channel count compared to 8-channel variants, the DAMEG1A allows you to reduce rack count and cabinet space significantly. In our experience, this module is the go-to choice when you need more than 8 analog outputs per rack and want to minimize hardware costs and cabinet footprint. For large control systems with 30 analog output points, the DAMEG1A can cut rack count in half compared to using 8-channel modules.

Reduces I/O rack count by up to 50% in large installations. 14-bit resolution with ±0.1% accuracy – provides precise control for all 16 channels. Suitable for demanding turbine control applications. 750 Ω load drive – supports cable runs up to 400 meters with standard positioners. Adequate for most turbine installations. Single-slot footprint – packs 16 outputs into the same physical space as 8-channel modules. Maximizes rack utilization. Rigorous 48-hour burn-in – each unit runs with all 16 channels loaded at 75% span. We verify accuracy and load drive on every channel. 3-year warranty on hardware – backed by our in-house repair depot with average 48-hour turnaround. Dedicated DAMEG1A swap-pool ensures rapid replacement. Frequently Asked Questions (FAQ) Can I hot-swap this IS200DAMEG1A into a running Mark VIe system? We strongly advise against it. The DAMEG1A draws significant current (450 mA) due to the 16 channels, and hot-swapping can cause backplane voltage dips. Schedule a controlled outage, de-energize the rack, and swap it during planned maintenance. How many of these modules can I put in a single rack? This depends on your backplane power supply. Each DAMEG1A draws 450 mA at 24 V. A standard Mark VIe backplane power supply can typically support 5-6 modules depending on other cards in the rack. We recommend keeping total 24 V loading under 80% of supply capacity. Calculate your total rack loading before ordering multiple units. What is the difference between the DAMEG1A and using two DAMAG1A modules? The DAMEG1A provides 16 channels in a single slot, saving rack space and reducing backplane connectivity. Two DAMAG1A modules would provide the same channel count but occupy two slots and consume more backplane bandwidth. However, the DAMEG1A uses group isolation (channels share a common reference), while the DAMAG1A has individual channel isolation. Choose DAMEG1A for space savings and lower cost; choose DAMAG1A for channel isolation. What is the maximum cable length with the 750 Ω load capability? With 18 AWG shielded cable (approximately 0.024 Ω/meter) and a typical 250 Ω positioner input, you can run up to approximately 400 meters (1,310 feet) and still stay within the 750 Ω limit. Total loop resistance = cable (both conductors) positioner any series resistors. For 400 meters, cable resistance is roughly 19 Ω total, so the loop would be 250 Ω 19 Ω = 269 Ω, well within the 750 Ω limit. Send us your loop specs for confirmation. Is there per-channel isolation on this module? No. The DAMEG1A uses group isolation, meaning all 16 channels share a common reference. This is a key difference from the DAMAG1A and DAMDG1A series, which have per-channel isolation. Group isolation is adequate for most applications but does not eliminate ground loops as effectively as per-channel isolation. Use per-channel isolated modules if you have complex grounding or high-EMI environments. 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 channels for accuracy and load drive. 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 all 16 channels. Plan for 4-6 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 90,000 hours for the DAMEG1A due to the higher component density and power consumption. Recalibration every 12 months is essential. The densely packed design runs hotter, so ensure adequate cabinet airflow. What happens if the module fails within the warranty period? We cross-ship a tested replacement from our dedicated DAMEG1A 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 DAMEG1A replacement. Which termination board should I use with this module? The IS200DAMEG1A mates with GE’s TS200DTE1 termination board, which is specifically designed for the 16-channel high-density configuration. Do not use DTA-series or DTD-series boards – they are not compatible with the 16-channel pinout. Double-check ribbon cable orientation; pin 1 has a red stripe. We include a wiring diagram PDF with every order.
