Features:
- Combines 16 configurable analog channels (16-bit, 10 kHz) with PROFIBUS DP master capability (125 slaves, 12 Mbps) in single pack
- Supports dual Ethernet, hot-backup, <1 ms network failover, and IEEE 1588 clock synchronization for uninterrupted operation
- Rated ATEX Zone 2, Class I Division 2 with 2.5 kV isolation, -20°C to +55°C operation, and MTBF >150,000 hours
The IS220PPRFH1A consolidates two critical functions into a single Mark VIe I/O pack: a PROFIBUS DP-V0 Class 1 master gateway and 16 channels of software-configurable analog I/O (4-20 mA or ±10 V). Traditional architectures required separate PROFIBUS gateway modules and analog input/output cards, consuming multiple rack slots and increasing wiring complexity. The IS220PPRFH1A eliminates this by integrating both functions on one board, reducing cabinet space by up to 30% and simplifying engineering . The PROFIBUS interface supports up to 125 slave devices at transmission rates from 9.6 kbps to 12 Mbps, with each slave handling up to 244 bytes of I/O data .
The IS220PPRFH1A is engineered for mission-critical turbine control applications where communication downtime is unacceptable. It offers three redundancy configurations: simplex (single I/O pack with one Ethernet connection), dual Ethernet (one pack with two network connections), and hot-backup (two packs each with dual Ethernet connections). In hot-backup mode, one IS220PPRFH1A operates as the active PROFIBUS master communicating with slave devices while a second pack remains in passive standby . The system continuously monitors the active pack's health; if a failure is detected, the standby pack assumes mastership with network switchover completing in less than 1 millisecond .
The IS220PPRFH1A is purpose-built for the demanding conditions of power generation facilities, including gas turbine decks, offshore platforms, and combined-cycle plants. It carries ATEX Zone 2 Group IIC and CSA Class I Division 2 Groups A,B,C,D certifications, allowing installation in potentially explosive atmospheres where flammable gases may be present under abnormal conditions . The pack provides 2.5 kV isolation between field channels and ground, and 500 V between channels, protecting the control system from lightning-induced surges and switching transients from large motors or switchgear .
The IS220PPRFH1A GE PROFIBUS Master may still be available for purchase and support from Apter Power beyond
End-Of-Life (EOL) by the manufacturer (OEM).
