Product Manual：

IS220PPROH1A Protection Input/Output Module
IS220PPROH1A is a GE Mark VIe series dedicated turbine emergency shutdown protection I/O module designed specifically for gas/steam turbine safety protection, with high reliability, strong redundancy, and safety priority.
Specially equipped with GE Speedtronic Mark VIe/VIeS control system for turbine emergency stop protection.
Dual 100Mbps full duplex Ethernet ports, high-speed access to IONet network, supporting redundant communication.
Integrated protection dedicated DI/DO channel, adapted to critical protection signals such as overspeed, vibration, temperature, etc.
Support TMR triple redundancy architecture to ensure high availability and security level of protection functions.
Built in independent protection logic, capable of independently executing emergency shutdown without relying on the main controller.
Electrical isolation between channels, with an isolation voltage of 2500Vrms, enhances system safety and anti-interference.

Industrial grade wide temperature design, working temperature -30 ℃~+65 ℃, suitable for harsh working conditions.
Metal compact shell, anti vibration and anti-interference, suitable for standard cabinet installation.
Support hot swapping, online replacement does not affect system operation and protection functions.
Built in channel level diagnosis, supporting alarms such as disconnection, short circuit, and power abnormality.
The panel LED status indicator facilitates quick on-site diagnosis and status confirmation.
Compatible with IS200 series protection terminal board, easy to expand and connect.
24VDC wide voltage power supply, compatible with 22.5-28.6VDC, suitable for on-site power supply.
Low power design reduces system heat dissipation and energy consumption pressure.
Approved by UL, CE, SIL safety certifications, suitable for hazardous industrial areas.
IS220PPROH1A, with its high safety, strong redundancy, and independent protection capabilities, has become the core module for turbine safety protection in the Mark VIe system.
