Power module 9440/22-01-21-C1243

Ex interface zone: 0, 1, 2, 21, 22 Protocols: Profibus DP V0, Profibus DP V1, Profibus DP V1 HART Redundancy: Full redundancy Nominal voltage: 120 V / 230 V AC Highlights - Suitable for Ex i V0/V1 HART PROFIBUS DP Supporting system redundancy and optical rings CPM in Zone 1 can be 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 - 9440/22 series CPU & power modules (CPM) for Zone 1 are used for the intrinsically safe supply of power to up to eight IS1+ I/O modules and to field circuits. Intrinsically safe RS485-IS with V0/V1 HART PROFIBUS DP is used for communicating with the automation system. These CPMs support system and optical rings and can be replaced while the system is in operation (i.e. hot swapped) in Zone 1/Division 1. A DTM and process bus or service bus are used for asset management integration.
