12-71 EAGLE QUANTUM PREMIER DEVICES
Version 6.0
Digital Communication Unit (DCU)
For gas detectors and other analog inputs
DCU’s are single channel analog input modules for the Eagle Quantum Premier LON. S 3 provides four variations
of software support for DCU’s, as follows:
Explosive •
For use with Det-Tronics catalytic bead combustible gas
detectors.
Oxygen
•
For use with Det-Tronics electrochemical oxygen depletion
cells.
Universal
•
Used with Det-Tronics line of electrochemical cells
measuring a variety of toxic gasses.
The “Universal” DCU can also be used with any standard
4-20ma* analog input and it for allows for the entry of user
assigned units and ranges.
DCU PointWatch
•
Used with Detector Electronics “PointWatch” PIR9400
series infrared point hydrocarbon detectors.
Note
*the actual range digitized by the DCU is between 0 and 24 mA because some field devices utilize the
over-range & under-range areas for diagnostic or other data.
