IS220PPRFH1A 336A4940CSP20

IS220PPRFH1A is a PROFIBUS DP V0 Class 1 Master Gateway I/O Pack designed by GE exclusively for the Mark VI/VIe control system. Its core function is to map, convert protocols, and bridge communication between PROFIBUS DP slave devices (sensors, actuators, third‑party instruments) and Mark VIe controller I/O Ethernet networks. It enables fieldbus signal integration, data acquisition, and control command output, suitable for distributed I/O and bus communication in gas/steam turbines and power plants, and is certified for hazardous area installation.

Product Overview

IS220PPRFH1A is a PROFIBUS DP V0 Class 1 Master Gateway I/O Pack designed by GE exclusively for the Mark VI/VIe control system. Its core function is to map, convert protocols, and bridge communication between PROFIBUS DP slave devices (sensors, actuators, third‑party instruments) and Mark VIe controller I/O Ethernet networks. It enables fieldbus signal integration, data acquisition, and control command output, suitable for distributed I/O and bus communication in gas/steam turbines and power plants, and is certified for hazardous area installation.

Core Functions

  1. PROFIBUS Master Communication: Acts as a PROFIBUS DP V0 Class 1 master, connects slaves via DE‑9 D‑sub RS‑485 interface, supports baud rates from 9.6Kbps to 12Mbps, connects up to 125 slaves, max 244 bytes I/O per slave.

  2. Protocol Conversion & Data Mapping: Converts PROFIBUS slave data to Mark VIe I/O Ethernet standard data for seamless interaction between controller and fieldbus devices.

  3. Redundancy Configurations: Supports three redundancy modes: single pack single network, single pack dual network, dual pack hot backup (automatic active/standby switchover) for high‑reliability communication.

  4. Status Diagnosis & Indication: Onboard LED indicators for real‑time communication, power, and fault status; configurable and diagnosable via ToolboxST software.

  5. Industrial‑Grade Safety Protection: Electrical isolation, surge suppression, compliant with hazardous area explosion‑proof/safety standards, adapted to harsh industrial EMI environments.

Technical Specifications

  • Power Supply: 28.0VDC (range 27.4–28.6VDC), max current 0.18ADC

  • Communication Interfaces: PROFIBUS DP RS‑485 (DE‑9), dual I/O Ethernet (10/100Mbps)

  • Operating Temperature: -20°C to +55°C (-4°F to 131°F)

  • Hardware: Common processor board + Hilscher COM‑C PROFIBUS communication daughterboard

  • Installation: Standard Mark VIe cabinet mounting, plugs directly into IS200SPIDG1A terminal board

  • Certifications: UL E207685, ATEX Zone 2 Group IIC, Class I Div 2 Groups A‑D

Typical Applications

  • PROFIBUS fieldbus integration for gas/steam turbine control systems

  • Bus communication gateway for Mark VIe distributed I/O and third‑party instruments/actuators

  • Hazardous area bus communication in power plants, combined‑cycle stations, industrial turbines

  • Hot‑backup redundant PROFIBUS master to ensure continuous and reliable unit control communication
