IS220PPRFH1B
Main Features and Advantages
Robust Communication Capabilities
The GE IS220PPRFH1B is equipped with a PROFIBUS RS – 485 interface provided by the COM – C module. Functioning as a PROFIBUS DP master, it can support up to 125 slaves, each capable of handling 244 bytes of inputs and outputs. With transmission rates ranging from 9.6 kbaud to 12 M baud, it enables high – speed and reliable data transfer. This makes it suitable for complex industrial setups where a large number of field devices need to be connected and controlled.
Redundancy Options
It offers multiple redundancy options. There’s the option of a single I/O Ethernet connection for a single I/O pack (no redundancy), a single I/O pack with two Ethernet connections for the I/Os, and hot – backup Ethernet connections with two ports. In a hot – backup system, two IS220PPRFH1B units are used, one active and communicating with slave devices via PROFIBUS, while the other remains passive in standby mode, ready to take over immediately in case of an active master failure. This redundancy significantly enhances the system’s reliability and uptime.
Compatibility and Ease of Installation
The IS220PPRFH1B is mounted on the PROFIBUS Master Gateway Terminal Board (SPI DG 1A), which also provides an electronic ID. The interface to the module is straightforward, with indicator LEDs on the front face of the module providing visual diagnostics. This makes it easy for maintenance personnel to quickly identify any issues. Additionally, the module’s design allows for easy integration into existing systems, reducing installation time and costs.
Wide Operating Temperature Range
With an ambient temperature rating of – 20 to + 55 °C (- 4 to + 131 °F), the GE IS220PPRFH1B can operate reliably in a variety of environmental conditions. Whether it’s in a cold industrial freezer or a hot power plant environment, this module can maintain its performance, ensuring continuous operation of the turbine control system.
Safety Certifications
The module holds ATEX Zone 2, Group IIC certification (UL Demko 12 ATEX 1114875X) and UL E207685 non – hazardous certification. These certifications ensure that the IS220PPRFH1B can be used safely in potentially explosive atmospheres as well as non – hazardous locations, expanding its application scope in different industrial settings.
