Main Features and Advantages
High-Density Isolated Outputs: The IS220PDOAH1B supports 16 discrete outputs, each isolated to prevent ground loops and electromagnetic interference. This density reduces the need for additional modules, simplifying system architecture in turbine control cabinets . Its fail-safe output configuration ensures outputs default to a safe state during power loss or fault conditions, critical for maintaining process safety in applications like emergency shutdown systems.
Redundant Power Design: With dual 28V DC inputs and automatic failover, the module ensures uninterrupted operation in applications where power outages could trigger turbine trips. Built-in overvoltage protection (OVP) safeguards against voltage spikes, while reverse polarity protection prevents damage from incorrect wiring .
Hazardous Location Certification: UL-listed for both non-hazardous and hazardous locations (Class I, Division 2), the IS220PDOAH1B is ideal for offshore platforms, refineries, and chemical plants where explosive atmospheres are present. Its metal enclosure and wide temperature range ensure reliability in corrosive and high-vibration environments .
Real-Time Diagnostics: LED indicators provide instant feedback on output status, power health, and communication activity. Integration with Proficy™ software enables remote monitoring of output signals, fault logging, and firmware updates, enhancing maintenance efficiency. The module also supports predictive diagnostics, allowing proactive identification of potential failures before they impact operations .
Flexible Terminal Board Compatibility: The module works with a range of GE terminal boards (e.g., TRLYH1B, TRLYH1E), allowing customization for specific actuator types (e.g., relays, solid-state switches). This flexibility enables seamless integration with existing field devices, reducing retrofitting costs .
