Model 88 LCD Programmable Indicator AccessoriesThe Model 88 is an LCD Indicator/Controller, with eight 7-segment digits. The display is an 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. The Model 88 Indicator/Controller 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 (8800-0000) can be programmed for - elapsed time, rate, preset count/time, count add/add, count add/sub, or count quadrature . Each base unit is normally powered from a DC voltage of 10-32 V. However, an AC power supply module (200557-002S) can be attached to the rear of the unit that converts 90-250 VAC to 12 VDC, which can be used to power the Model 88 and an external sensor. Another module (200557-001S) can be added that converts the discrete output of the Model 88 base unit to relay contacts. - Features ?NEMA 4X/IP56 Sealed Panel ?UL, cUL Recognized, CE Compliant UL File # E19514 - Options ?Relay Module 200557-001S 2 Form C, 5 Amp Relays ?AC Power Module 200557-002S +90 VAC to +285 VAC, 50/60 Hz (Unit Is Normally Powered From +10 VDC to +32 VDC)
