Reliable valve status communication
Features
- 24 VDC input from ESD system
- 4/20 mA output to VG9000H
- Two status relays (test, alarm)
- PST start via separate 24 VDC input
- HART communication
- Isolated Ex barrier
- Up to SIL3 acc. to IEC 61508
Benefits
RCI9H2 for VG9000H provides reliable and safe status information of ESD valves for shutdown systems. Included isolated barrier eliminates additional component need in intrisically safe applications.
