1–7 Overview of the CFM Module
Publication 1771Ć6.5.99 - December 1995
The CFM module has four assignable outputs. These outputs are
designed for applications that require fast response. The outputs:
•
are electrically fused/current limited to 3A (output combinations
are limited to 7A)
•
can be assigned to any input channel with user-selectable turn-on
and turn-off values
•
are current sourcing at 5-40V dc (1A maximum per output)
•
must be connected to an external power supply
•
are in groups of two — this lets you use two separate external
power supplies if desired (one for outputs 0&1 and one for
outputs 2&3)
Outputs may be forced on or off independent of count or
frequency value. They may be forced on and off by setting bits in the
BTW configuration block.
Important: You can assign as many as four outputs to a given
channel; however, you can not use the same output with
two different channels.
In this mode
of operation
You can assign outputs that are programmable to trigger
Totalizer
on total, rate, rate change (acceleration), total overflow or
prover status
Nonresettable Totalizer on total, rate, rate change (acceleration), total overflow or
prover status
HighĆresolution
Frequency
on frequency or frequency rate of change (acceleration)
Direction Sensor
on either CLOCKWISE or COUNTERĆCLOCKWISE direction,
acceleration or frequency (outputs are triggered ON only)
