Ship approval: ABS, BVIS, EU RO MR (DNV), KR, LR
Installation: Zone 1/Division 1
Protocols: Profibus DP V0, Profibus DP V1, Profibus DP V1 HART
Redundancy: Full redundancy
Nominal voltage: 24 V DC
Highlights:
Suitable for Ex i Profibus DP V0/V1 HART
Supports system redundancy and optical rings
CPM in Zone 1 can be replaced without having to disconnect the power supply (i.e. hot-swapped)
Integration in plant asset management systems via ServiceBus and FDT/DTM
Integrated Ex i power supply for up to 8 I/O modules
Functional Description:
Series 9440/22 CPU & power modules (CPM) for Zone 1 are used to supply up to 8 IS1+ I/O modules and field circuits with intrinsically safe power. Intrinsically safe RS485-IS with PROFIBUS DP V0/V1 HART is used for communicating with the automation system. The CPMs support system redundancy and optical rings and can be replaced during operation (i.e. hot-swapped) in Zone 1/Div. 1. A DTM and process bus or ServiceBus are used for asset management integration.
