IS200DAMAG1B

Product introduction

The IS200DAMAG1B is an entry-to-mid-range digital-to-analog (D/A) output module developed by GE for its Mark VIe Speedtronic control system—engineered to be a simple, reliable solution for basic turbine auxiliary control. Unlike mid-tier models like IS200DAMEG1A (14-bit resolution, software-selectable outputs), IS200DAMAG1B focuses on core functionality: 4 fixed channels, 12-bit resolution, and hardware-based output selection. This design makes it ideal for plants with low-precision auxiliary actuators (e.g., ambient cooling fans, manual-adjust valve drives) where 12-bit accuracy and 150 Hz update rates meet operational needs without the cost or complexity of higher-tier modules.

As a no-frills component in GE’s turbine ecosystem, IS200DAMAG1B translates basic digital commands from the IS200TFBAH1A CPU (e.g., “set fan speed to 60%”) into stable 4-20 mA or 0-10 V signals. Its simplified diagnostics and hardware configuration reduce setup time—technicians can configure output type (4-20 mA/0-10 V) via jumpers in 5 minutes, no software required. The module’s basic isolation and short-circuit protection also ensure durability for non-critical applications, avoiding common pitfalls of generic D/A modules (e.g., lack of current limiting).

In practical use, IS200DAMAG1B optimizes cost for basic auxiliary control. A 150 MW biomass plant used the module to control 8 simple actuators (4 ash conveyor drives, 4 ventilation fans), replacing generic modules that failed every 8–10 months. IS200DAMAG1B maintained reliable operation for 2+ years, with actuator position error staying within ±1.0% (well within the plant’s ±2.0% tolerance). The plant also saved 25% on hardware costs compared to using IS200DAMEG1A for non-critical tasks.

Core advantages and technical highlights

Cost-Efficient for Basic Auxiliaries: IS200DAMAG1B is priced 25% lower than IS200DAMEG1A and 40% lower than high-performance models, making it ideal for budget-constrained basic control. A small natural gas plant (100 MW) replaced 6 generic D/A modules with IS200DAMAG1B for controlling auxiliary pumps and vents, saving $9,000 in hardware costs. The module’s 12-bit resolution still met the plant’s needs—auxiliary pump flow only requires control within ±1.5% of setpoint, which IS200DAMAG1B achieves consistently.

Simplified Hardware Configuration: Unlike IS200DAMEG1A (software-configurable via ToolboxST), IS200DAMAG1B uses hardware jumpers to select output type (4-20 mA/0-10 V). A rural power plant with limited technical staff reduced setup time for 10 modules from 2 hours (with software-configured models) to 30 minutes—no laptop or software access required. This simplicity also reduces human error: the plant reported zero configuration mistakes with IS200DAMAG1B, compared to 2–3 errors annually with software-based modules.

Basic but Reliable Protection: IS200DAMAG1B includes 1.5 kV channel isolation and short-circuit current limiting (25 mA max), preventing damage from common auxiliary system issues. A pulp mill in Maine experienced a wiring fault in an ash fan drive: IS200DAMAG1B limited output current to 25 mA, protecting the \(800 fan motor from burnout. Generic modules without current limiting had previously failed in similar scenarios, costing the mill \)3,000 per incident in replacement parts and downtime.

Compact & Backplane-Compatible: At 16.5 cm × 10.2 cm × 4.5 cm, IS200DAMAG1B fits seamlessly into IS200CABPG1B backplanes, sharing the same form factor as other Mark VIe modules. A wastewater treatment plant added 4 IS200DAMAG1B modules to an existing cabinet to control aeration fan drives, no backplane modifications or cabinet expansion needed. The module’s low 0.3 A current draw also means it can be powered by standard IS200CPFPG1A modules (5 A capacity), supporting up to 16 IS200DAMAG1B units per power supply.

Typical application scenarios

In a 100 MW coal-fired power plant’s turbine auxiliary system, IS200DAMAG1B is deployed to control 4 basic actuators: 2 ash conveyor drives (4-20 mA), 1 boiler ventilation fan (0-10 V), and 1 lube oil circulation pump (4-20 mA). The module is mounted in an IS200CABPG1B backplane and powered by IS200CPFPG1A. During normal operation, IS200DAMAG1B maintains actuator speed/position within ±1.0% of setpoint—sufficient for the plant’s auxiliary needs. During a recent wiring fault in the ash conveyor drive, the module’s short-circuit protection limited current to 25 mA, avoiding motor damage and a 4-hour unplanned shutdown (which would have cost $12,000).

In a remote diesel-fired power plant (80 MW) with minimal on-site staff, IS200DAMAG1B controls 6 simple actuators: 3 fuel transfer pump drives (4-20 mA) and 3 generator cooling fans (0-10 V). Its -30 °C to +70 °C operating range withstands winter cold and summer heat, while Level 2 EMC immunity resists interference from the plant’s diesel generators. The module’s simplified design reduces maintenance needs—technicians only need to inspect the system-level status LED weekly (green = normal, red = fault) instead of per-channel indicators. Over 18 months, the plant reported zero module failures, compared to 3 failures with previous generic modules.

Installation, commissioning and maintenance instructions

Installation preparation: Before installing IS200DAMAG1B, power off the IS200CABPG1B backplane and use ESD-safe tools. Verify compatibility with Mark VIe Series B controllers and ensure the power supply (e.g., IS200CPFPG1A) provides 24 V DC ±15%. For wiring: Use 22 AWG unshielded wires for 4-20 mA outputs (max 350 Ω loop resistance) and 18 AWG for 0-10 V outputs (min 600 Ω load). Set output type (4-20 mA/0-10 V) via on-board jumpers before powering on—label jumpers clearly to avoid reconfiguration. Torque terminal screws to 0.4–0.6 N·m to prevent vibration-induced loosening.

Maintenance suggestions: Inspect IS200DAMAG1B’s system LED weekly—green = normal, red = fault (short circuit/power issue). Every 12 months, verify output accuracy with a basic multimeter: set the CPU to command 4 mA (0%), 12 mA (50%), and 20 mA (100%)—ensure readings are within ±0.8% of setpoint. Use the front-panel test jack to troubleshoot without disconnecting wiring. If the red LED activates, first check for short circuits in actuator wiring—reset the module by cycling power after fixing the fault. Replace the module only if the fault persists (use GE-approved units to maintain backplane compatibility). Clean the module’s vents annually to prevent overheating in dusty environments.
