GE IS220PAICH1A 336A4940CSP3 Product Specification
Product Overview
The GE IS220PAICH1A 336A4940CSP3 is a high-reliability analog I/O pack designed for GE’s Mark VIe Speedtronic Turbine Control System, optimized for hazardous and non-hazardous industrial environments. This variant of the IS220PAICH1A series integrates advanced signal conditioning, power management, and safety certifications to meet the demands of critical applications in oil & gas, power generation, and chemical processing. The 336A4940CSP3 designation likely represents a specific configuration or revision optimized for hazardous locations, with enhanced power supply requirements and compliance with rigorous safety standards 1518.
Featuring 16 isolated analog inputs (4–20 mA, 0–10 VDC) and 8 relay outputs (24 VDC/2A max), the module interfaces with sensors (e.g., pressure transmitters, RTDs) and actuators (e.g., solenoid valves, contactors) while maintaining 500 Vrms electrical isolation to prevent ground loops. Its dual Ethernet ports support high-speed communication with Mark VIe controllers, enabling real-time data exchange in simplex or triple modular redundant (TMR) architectures 3612. The 27.4–28.6 VDC power supply (nominally 28 VDC) ensures stable operation in environments with voltage fluctuations, a key distinction from standard IS220PAICH1A models 15.
Constructed with a triple-layer conformal coating and IP65-rated enclosure, the IS220PAICH1A 336A4940CSP3 withstands extreme temperatures (-30°C to +65°C), humidity (5–95% non-condensing), and vibration (75 G peak). Its hot-swappable design allows field maintenance without system shutdowns, while front-panel LEDs (Power, Run, Fault) provide real-time diagnostics 17. The module’s compact form factor (263 × 58 × 28 mm, 0.36 kg) facilitates integration into space-constrained industrial racks 118.
