Description
Product Overview
The 1C31179G02 (P/N: 1C31179G02) and 1C31227G01 (P/N: 1C31227G01) are specialized S-series FOUNDATION Fieldbus H1 interface cards engineered for the Emerson DeltaV environment. These modules serve as a bridge between the digital control network and field instrumentation, featuring a dual-segment architecture with integrated power conditioning. By merging the H1 controller and power supply into a single footprint, this hardware minimizes cabinet footprint, simplifies wiring complexity, and enables high-resolution device diagnostics alongside synchronized control-in-the-field capabilities.

Technical FAQ
What distinguishes the 1C31179G02 from the 1C31227G01 variant?
The 1C31227G01 (1C31227G01) is specifically identified as the variant featuring integrated segment power conditioners. This allows the card to directly energize the fieldbus loop. In contrast, the 1C31179G02 (1C31179G02) may be utilized in configurations where external power supplies are already present or required by specific loop designs.
Is redundancy supported for these H1 cards?
Yes. Both the 1C31179G02 (1C31179G02) and 1C31227G01 (1C31227G01) support 1:1 hardware redundancy. When installed in a redundant carrier, the standby module takes over communication immediately upon primary failure to prevent process disruption.
How is device configuration managed?
All connected Fieldbus instruments are configured via DeltaV Control Studio. The interface facilitates the transparent flow of data to AMS (Asset Management Solutions) for deep-level device calibration and health monitoring.
