The H1 card requires external fieldbus power supplies to power the fieldbus devices. The H1 with Integrated Power card provides the fieldbus power required for most applications. Emerson recommends the use of the H1 with Integrated Power card for most fieldbus applications because it requires less cabinet space and wiring, resulting in lower installation costs. In addition, the H1 with Integrated Power card provides individual integrated segment power diagnostics to complement existing hardware alerts and segment communication statistics without additional components or wiring.
