<4. ANALYZER COMPONENTS>
The unit acts as a remote interface for the analyzer. Should the physical location of the actual analyzer(s) be
inconvenient for easy access, then the RIU can be used.
It can be mounted up to 100m (330ft) away from the analyzer(s) using the standard 10-BaseT twisted pair
wiring method. It communicates to the analyzer(s) through a Virtual Network Connection (VNC). If there is more
than one analyzer connected to the RIU, then they are routed via an industrial Ethernet switch. Up to four
analyzers can be routed through one RIU switch.
The RIU Enclosure is die cast copper free aluminum grade AL Si 12 alloy (A413.0) with a powder coat exterior
finish. The copper free aluminum alloy is particularly resistant to salt atmospheres, sulfur gases and galvanic
corrosion. An externally hinged door opening to the left incorporates a weather tight gasket seal and four
captive fastening screws (stainless steel). The external dimensions are approx 16” W x 12” H x 7” D (400mm x
300mm x 180mm). Wall mounting brackets are included with the RIU.
The environmental protection rating is considered IP65 (EN 60529) or NEMA 4X. Cable entries are located on the
bottom face of the enclosure. They are typically ¾” Myers hubs that have ¾” NPT female threads. Each has a
ground lug to facilitate the grounding of cable shields to the chassis.
The RIU is supplied with standard integral display and keypad.
RIU Interconnect to Launch Control Unit(s)
When connecting just one analyzer to the RIU there are two twisted pair wires to consider , there
are only four wires to be terminated to make the 10/100 Ethernet connection.
