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
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.
