RCI9H is intended to be used together with the Neles ValvGuard VG9000H safety valve controller. It is needed when a 24 VDC output (DO) is used in the safety system. RCI9H also includes an isolated barrier and can thus also be used for intrinsically safe applications. RCI9H 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. 24 VDC input from ESD 4/20 mA output to VG9000H Isolated barrier Line fault detection (LFD) Up to SIL3 acc. to IEC 61508 IEC61508 certificate RCI9H is approved by exida to be used in safety applications up to and including safety integrity level 3 (SIL3).

ADDITIONAL ACCESSORIES Power feed modules KFD2-EB2 The Pepperl+Fuchs power feed module is used to supply the device with 24 V DC via the Power Rail. The fuse-protected power feed module can supply up to 100 individual devices depending on the power consumption of the devices. A galvanically isolated mechanical contact uses the Power Rail to transmit collective error messages.
