Description

Application

  • The 7916 backplane is a compact and robust solution that enables a safe and easy connection of PR system 9000 IS device signals into standard automation systems.
  • 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 level of functional safety, even when mounted in the backplane solution.

Technical characteristics

  • Robust, compact high-end design that holds 16 system 9000 units.
  • Digital output indicates status of the 9000 devices and primary/back-up power supplies.
  • Flexible 24 VDC supply voltage and redundant power supply connection solution.

Mounting / installation / programming

  • Flexible horizontal/vertical panel or wall mounting in the Safe or Zone 2 / Div 2 areas.
  • System 9000 devices easily snap ON and OFF using piano keys, and devices can be hot-swapped.
  • Tag number and ID labels are easily mounted and read by using the dedicated piano key spacer.
  • Wide temperature operation range: -20…+60°C.
