Product Description
| Application: | the 7908 backplane is a compact and robust solution that enables a safe and easy connection of up to 8 PR system 9000 IS device signals into standard automation systems |
| Functions: | standard automation system cables and connectors are used to link the backplane to the I/O cards the backplane can be used for Direct, Redundant, Duplicate signalling including HART I/O System connectivity (HART MUX) the system 9000 devices isolate and convert AI, AO, DI and DO signals coming from, or going to the I.S. classified area, and routes those signals to a system automation I/O card the system 9000 units maintain a SIL2/SIL3 level of functional safety, even when mounted in the backplane solution |
