APPLICATION
Batch control, cut to length, packaging, blending. The
display may be toggled between total, rate, and grand total.
Programmable K-factor makes keying - in engineering units
easy. Unit accepts pulse, contact closures or analog input
and provides two separate preset controls.

DESCRIPTION
Featuring 8 digits of bright, .55”, alphanumeric display, the
pulse input version of the unit can accept up to 20,000
pulses per second. The analog input version accepts
inputs, such as 4 to 20mA or 1 to 5V. It uses a highly linear
integrator (V to F converter) to generate 0 to 10KHz digital
pulses. The unit has two separate, 8 digit, floating decimal,
“K” factors to convert the inputs to meaningful count and
rate data. The user, with the push of a button, can toggle
back and forth to view the total of the batch, the rate of flow
and the grand total count.
Two controls outputs can be assigned independently by the
user to activate at preset batch count, rate or grand total for
.1 to 9.9 seconds or until reset externally.
A scaled pulse output is also provided by an open collector
driver. Since the output frequency is user selectable at 10,
200, 2K or 20KHz, the unit can transmit the count data to
electromechanical or electronic counters as well as computers, programmable controllers or other monitor equipment.
An optional analog 4 to 20mA output, selectable between
rate or total, allows the user to select 4mA and 20mA rate
settings to control strip chart recorders or other peripherals.
Up to 15 units can be connected to optional RS232 or
RS422 communications port to set control points or access
data. With RS422M up to 256 units can be linked together
and addressed separately to transmit unit states or accept
new set points. The Baud rate is “Auto Ranging” from 300
to 19.2K. It is also OPTOMUX Compatible.
