GE IS220PDIIH1B 336A5026ADP1 Mark VIe Digital Input Module
Product Overview
The GE IS220PDIIH1B 336A5026ADP1 is a high-reliability digital input module designed for GE’s Mark VIe control system, serving as a critical interface for monitoring digital signals in industrial automation. As part of the IS220 Series, this module converts discrete electrical signals from sensors, switches, and relays into digital data for processing by the system’s central controller, enabling real-time status monitoring of machinery and processes. The IS220PDIIH1B 336A5026ADP1 integrates seamlessly with other Mark VIe components (e.g., analog output modules, communication cards), forming a robust control architecture for mission-critical applications in power generation, oil & gas, and manufacturing.
Featuring 32 independent digital input channels, the GE IS220PDIIH1B 336A5026ADP1 supports 24 V DC input signals, with galvanic isolation (2500 V RMS) between channels to prevent electrical interference. Its 16-bit processing core ensures fast signal detection (response time <1 ms), critical for capturing rapid state changes in safety systems and high-speed machinery. The module’s rugged design includes a conformal coating and compliance with MIL-STD-810G for vibration, shock, and temperature extremes (-40°C to +70°C), making it suitable for harsh environments like offshore platforms and power plant turbine halls.
In automation ecosystems, the IS220PDIIH1B 336A5026ADP1 monitors critical statuses such as valve positions, limit switch triggers, and emergency stop signals, feeding data to the Mark VIe controller for decision-making. Its support for triple modular redundancy (TMR) configurations enhances system reliability by cross-verifying inputs across three redundant modules, ensuring fault tolerance in safety-critical setups. The hot-swappable design allows maintenance without system shutdown, minimizing downtime in 24/7 operations—an essential feature for industries where unplanned outages incur significant costs.
