Optimus™ Control Module
The Optimus™ control module is not suitable for use in hazardous areas and is normally
situated in the control cabinet in the safe area. It can be mounted using top hat 35mm
DIN rail.
Each PRI150 radiation detector in the sys
tem connects to the Optimus™ control module
via an isolated HART 4-20mA repeater power supply. Proprietary algorithms and
processing are performed on the system data to provide the system level as a passive 4-
20mA loop current signal or via the HART 7 interface where additional diagnostic
information including an indication of vessel build up is also available.
