RCI9H2 for Neles™ ValvGuard™ VG9000

Reliable valve status communication

RCI9H2-for-Neles-ValvGuard-VG9000.jpg

RCI9H2 is intended to be used together with the Neles ValvGuard VG9000H. It is needed when a 24 VDC output (DO) is used in the safety system. RCI9H2 is connected between the safety system and the field device VG9000H. The primary function of RCI9H2 is to convert a safety DO into a SIL 3 compatible 4-20mA current signal. RCI9H2 also provides relay outputs for monitoring the test and alarm status of the VG9000H.

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. 

Applications

  • SIL 3 certified according to IEC 61508
  • HART communication
  • Status relays
