765 Series Automatic Timing & Controls automatictiming.com 800.727.5646 118 Panel Mounted Digital Timers // 765 Series The ATC 765 Step Controller is the perfect alternative to cam timers and micro PLC’s for simple sequential applications. The 765 is a powerful, compact, economical sequential control that features an extremely user friendly programming format. Microprocessor-based, it offers 100 control levels or steps, 8 programmable relay outputs, functions with count input signals or timed input with 4 timing range values from 0.01 seconds to 99 hours/59 minutes and a host of other primary and secondary keypad functions. A cost-effective control, the Model 765 is an ideal alternative to cam timers and micro PLCs for sequencing operations. Equipped with EEPROM memory, the Model 765 can store programmed information indefinitely, without battery back-up, freeing PLCs from memory storage that can be better applied for more critical data retention tasks. It step advances on the basis of time or count which can be intermixed from one control step to the next if desired. Sealed for the harsh industrial environment, the Model 765 is equally at home in the laboratory for quality control or test applications.
