PRODUCT INFORMATION
Product Overview
The General Electric IS220PPROH1A is an I/O Protection Module for Mark VI and Mark VIe systems. This turbine-specific I/O pack interfaces directly with dedicated turbine field devices and emergency trip systems. It is deployed in aeroderivative turbine emergency trip configurations and monitoring architectures. The unit supports both Triple Modular Redundancy and simplex backup protection schemes across turbine control platforms.
The module includes a high-speed processor, a watchdog timer, and an internal temperature monitoring sensor. Dual independent 10/100 Ethernet ports provide network connectivity via ENET 1 and ENET 2 channels. Hardware-implemented trip logic calculates speed signals for deceleration, acceleration, and overspeed detection. The circuit board features H1 conformal coating for operating protection in demanding industrial environments.
