GE IS220PPRAS1B Turbine Input/Output: Turbine Backup Protection

Function Description

IS220PPRAS1A is a HART enabled analog input/output module developed by General Electric and is part of the Mark VIe control system. 

It serves as a critical connection point, providing electrical interfaces between one or two input/output (I/O) Ethernet networks and analog input/output terminal boards. 

This package includes a standardized processor board suitable for all Mark VIe distributed I/O packages, 

as well as a customized acquisition board for specific requirements of analog input functionality. 

With powerful analog input capabilities, HART communication support, and a range of connection options, 

it is a valuable supplement for industrial systems that rely on precise analog signal management and communication with intelligent field devices.

Features

Analog input capability:capable of managing up to 10 analog inputs, 

making it a valuable component for processing various analog signals within industrial systems.

Current loop input: For current loop input, the load terminal resistor is conveniently located on the terminal board.

PHRA can sense the voltage across these resistors, which helps to accurately measure and interpret current loop signals.

The IS220PTURH1A has a black outside shell with air circulation holes. 

This case contains various LED indicators on the front, as well as an IR receiver (infrared port.) This bundle does not use this port. 

A CPU board, a second board dedicated to turbine control, and an analog acquisition auxiliary board are all housed within this case.

The TTURH1C terminal board is used to mount the pack. Two 10/100 Ethernet ports, flash memory, RAM, a read-only chip for identification, 

an internal temperature sensor, and a reset circuit are all on the processor board.

The IS220PTCCH1A offers a maximum software error/conformity error of .25 degrees Fahrenheit. 

Common mode voltage is +/- 5 volts with AC common-mode rejection of 100dB @50/60Hz. 

Common mode rejection includes filtering for both hardware and software. 

The unit also includes normal mode rejection of 250 mV RMS @ 50/60 Hz (+/-5%) and high/low hardware and software limit checks. 

The unit is designed for operation in ambient conditions from -22 to +149 degrees Fahrenheit.

The IS220PTCCH1A can perform multiple self-diagnostics including power-up self-tests of flash memory, RAM, processor board hardware, 

and Ethernet ports. It also offers continuous monitoring of its internal power supplies to ensure proper functions. 

Additional information about the IS220PTCCH1A, including important handling and installation instructions and warnings, 

can be found in GE product manuals and guides.Generally, this IS220PTCCH1A device's voltage suppression and limitation strategy 

involves its normal Mark V Series assembly's acceptance of various series-standardized limiting hardware component such as various styles of capacitors, 

resistors, transistors, diodes, and specialized integrated circuits.
