GE IS220PAOCH1A Mark VIe Analog Output Module
Product Overview
The GE IS220PAOCH1A is a high-precision Analog Output Module designed for GE’s Mark VIe control system, engineered to deliver accurate and reliable analog signals for industrial automation applications. As part of the IS220 Series, this module plays a critical role in converting digital control signals into precise analog outputs, enabling seamless interaction with actuators, valves, and other analog-controlled devices. The IS220PAOCH1A is optimized for harsh industrial environments, featuring rugged construction, high-resolution outputs, and redundant configurations to ensure uninterrupted operation in mission-critical systems.
Featuring 8 independent analog output channels, the GE IS220PAOCH1A supports both 4–20 mA and 0–10 V signal ranges, with 16-bit resolution and ±0.05% accuracy to provide precise control over industrial processes. Each channel includes galvanic isolation (1500 V RMS) to prevent electrical interference and ensure signal integrity, even in noisy industrial environments. The module’s hot-swappable design allows for maintenance without system shutdown, minimizing downtime in continuous-operation environments. With support for triple modular redundancy (TMR) configurations, the IS220PAOCH1A provides fault tolerance and enhances system reliability by voting on outputs from three redundant channels.
In industrial settings, the IS220PAOCH1A is commonly used to control variables such as temperature, pressure, and flow rate in gas turbines, steam turbines, and other critical equipment. Its high-speed update rate (up to 100 Hz) ensures responsive control, while diagnostic features monitor channel health and detect faults such as open circuits or short circuits. The module’s conformal coating and compliance with MIL-STD-810G for vibration, shock, and temperature extremes (-40°C to +70°C) make it suitable for deployment in harsh environments such as offshore platforms, mining operations, and power plants.
