GE IS220PTURH1B IS220PTURH1BF Turbine I/O Pack

The GE IS220PTURH1B IS220PTURH1BF Turbine I/O Pack manages distributed I/O signals for turbine control networks. You will find this compact pack ideal for remote mounting near field devices. Its modular design simplifies installation in tight turbine auxiliary cabinets.

Dimensions, Weight, and Mechanical Layout

This turbine I/O pack measures 14.5 cm in length and 9.8 cm in width. Its height stays at 4.2 cm including the DIN-rail clip. The total weight reaches 0.38 kilograms for easy one-handed handling. A rugged aluminum housing provides excellent electromagnetic interference shielding.

I/O Interfaces and Component Count

The GE IS220PTURH1B IS220PTURH1BF Turbine I/O Pack offers 8 universal analog inputs and 6 digital outputs. You also get two isolated RS-485 ports for Modbus communication. A single CAN bus interface supports high-speed data exchange with the main controller. In total, this I/O pack contains 94 individual electronic components.

Energy Storage and Power Parameters

A 3.3V supercapacitor provides onboard energy storage for 36 hours. This backup retains I/O configuration data during temporary power loss. The pack draws only 3.8 watts from a nominal 24V DC supply. Peak inrush current stays safely below 1.8 amperes.

Memory, Processing, and Environmental Limits

You get 32 MB of flash memory for firmware and scaling tables. The board also includes 16 MB of SRAM for real-time data buffering. A 120 MHz ARM Cortex-M3 processor handles all I/O scanning tasks. Therefore, the operating temperature ranges from -30°C to +65°C. Storage temperatures extend from -40°C to +85°C without damage.

Connectors, Wiring, and Additional Features

Two 10-pin spring-clamp terminal blocks accept 18–24 AWG field wiring. A single 6-pin power connector provides 24V DC input and earth ground. For similar static trip monitoring applications, see the RMS-TSG-TZ-C model from the same manufacturer. However, this turbine I/O pack specializes in distributed turbine control exclusively. Mean time between failures (MTBF) exceeds 110,000 hours in continuous operation.
