Description
The Model 88 is a family of LCD Indicators/Controllers, with eight 7-segment digits that are 0.35” [9mm] in height. The standard display is a backlit LCD,
providing red characters on a dark background. An optional reflective LCD with dark characters on a light background is available. Unit programming
is accomplished using four front-panel switches, or programming can be done using the optional serial data interface and dedicated PC-based software
(Redi-Ware), which is available from Redington free of charge. Upon power up, the Indicator/Controller performs internal diagnostics and flashes all seg-
ments of the display “ON” and “OFF” several times. The Indicator/Controller then configures itself per previous programming, loads the internal Counters
and Timers with their values prior to power down, and begins normal operation.
The Model 88 Indicator/Counter is capable of receiving counts and/or analog inputs, processing those inputs in a number of different selectable ways,
and then providing outputs in several formats. Base units, i.e. #8800-0000, 8802-0000, or similar units can be programmed for Elapsed Time, Rate,
Preset Count/Time, count Add/Sub, or Quadrature. The count inputs can be prescaled from -9.9999 to 99.9999. On the 8802 units, the prescale can be
further multiplied by 10
be either prescaled count per hours (PPH) or per minute (rpm). The two independent control outputs are open-collector (NPN) outputs that can be con-
trolled by either count inputs, time, rate, the analog input, or combinations of these inputs. Based on two inputs, the indicator is capable of displaying two
counts, a rate indicator and an elapsed time at the same time. The base unit provides the display, programming, and processing functions for the final
configuration as well as the counter I/0 function. I/0 functions and installed modules are available that allow the user to configure complex functions into
a small enclosure. Other models add analog input/output functions to the base unit, and serial communication functions, which supports RS232/RS422/
RS485, providing the user with a broad selection of configurations.
Each Model 88 base unit is normally powered from a DC voltage of +10V to + 32 V. However, an AC power supply module # 200557-002S can be at-
tached to the rear of the unit that converts +90VAC to +250VAC, to +12VDC, which can be used to power the Model 88 and an external sensor. Another
module, 200557-001S, can be added that converts the discrete outputs of the Model 88 base unit to relay contacts.

Predetermining
Preset units provide two discrete outputs which can
be controlled as a function of count, rate, elapsed
time, or analog input. Each control output can be set
by any of the four functions and reset by the same
or a different function. For example, control output
1 could be set when a specific count is reached and
reset when an analog input level is reached.
