General
The Panel Mount MC-II
Plus Flow Analyzer is available in three configurations, ¼
DIN, Double Wide Single Readout and Double Wide Two Readout.
The ¼ DIN unit mounts in the DIN standard ¼ DIN square opening (3.62” X 3.62”).
Due to variations in mounting situations some mounting fasteners are to be supplied
by the installer. Studs (#6-32 X ¾”) and nuts (#6-32) with integral lockwasher are
supplied for mounting the instrument. Mounting dimensions are shown on page A1-
7.
The Double Wide Single Readout unit fits in an industry size rack and is especially
suited for replacement of Double Wide NuFlo Model LO-II Flow Totalizers as well as
new installations. Mounting dimensions are shown on page A1-8.
The Double Wide Two Readout unit fits in the same size rack as the Double Wide
Single Readout unit. This instrument provides two readouts in the same space as
one readout as supplied in the above unit. It is especially suited for replacing one
Double wide NuFlo Model LO-II Flow Totalizer with two Panel Mount MC-II
Plus
Flow Analyzers. It is also suited for replacing two standard width NuFlo Model LO-II
Flow Totalizers in the same space. Mounting dimensions are shown on page A1-9.
Input / Output Features
There are five input/output features available for the Panel Mount MC-II Plus Flow
Analyzer. Each feature is covered individually in the following sections with wiring
diagrams.
Pulse Output
The Pulse Output is provided in the form of an optically isolated open collector
transistor circuit. It can be used in conjunction with any other feature on the Panel
Mount MC-II
Plus Flow Analyzer. A two-conductor cable from the Panel Mount MC-
II Plus Flow Analyzer to the remote location is required with a 5 to 30 VDC power
supply and suitable device for reading the open collector pulse output of the Panel
Mount MC-II
Plus Flow Analyzer. The maximum current rating of the pulse output
circuit is 40 mA @ 30 VDC. The Pulse Output Wiring Diagram is located on page
A1-11.
The section in the manual,
Configuring the Pulse Output , provides information
regarding the setup of the pulse output feature.
