Neles RCI9H2 Remote Communication Interface for Valvguard VG900H

Brand: Valmet
Request Information
Favorite

Remote Communication Interface RCI9H2 is intended to be used together with the Neles ValvGuard VG9000H intelligent safety solenoid. 

When 24 Vdc output (DO) in the safety system or logic is used RCI9H2 is needed between the DO and VG9000H field device. 

The primary function of RCI9H2 is to convert binary signal to SIL 3 compatible 4/20mA current signal. 

RCI9H2 also provides relay outputs for monitoring the test and alarm status of the VG9000H and a discrete input for commanding VG9000H to start a PST (Partial Stroke Test). 

Additionally, RCI9H2 includes an isolator barrier and can be used in intrinsically safe applications. 

RCI9H2 provides HART communication for diagnostics and configuration of the VG9000H. 

The HART communication is available when a 24 Vdc power supply is connected, also during the emergency trip.
