Description

The Model 88 is a programmable LCD Totalizer, 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 Totalizer performs internal diagnostics and ﬂashes all segments of the

display “ON” and “OFF” several times. The Totalizer 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 Programmable Totalizer is capable of receiving input pulses, processing those input pulses in a number of different, selectable ways, and

then displaying the results. The Totalizer is capable of operating in a single-up count mode, as well as add-subtract, directional counting, add-add, and

three levels of quadrature. In addition, the unit can support independent counting of tow separate inputs. Counts can be pre-scaled by scale factors rang-

ing from -9.9999 to 99.9999 or from -9.9999 x 10

dual count mode. Maximum input speed can be limited by enabling an analog ﬁlter on each input, thereby protecting count integrity from unwanted noise.

The input format can also be selected. In addition, a serial data interface option is available to report counts from remote locations or to program the

Totalizer. 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 attached 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.
