PANEL MOUNTED DIGITAL TIMERS 651 Series Multi-Function Multi-Range Timer WIRING The ATC 651 is a microprocessor-based device that is selectable between four different timing modes and five different timing ranges. The timing modes include On-Delay, Reverse Start Delay, Momentary Start Single Cycle Flip Flop, and Accumulator. The timing ranges allow for delays from 1 millisecond to 199 hours 59 minutes. The timing modes and ranges are selected using a DIP switch assembly located on the inside of the timer. The time setting is entered through the keyboard located in the timer faceplate while the time value is displayed on the LCD readout. The timer keyboard can be disabled to guard against acci- dental time changes. The 651 timer is housed in a standard 15-terminal plug-in round case and will directly replace an existing electromechani- cal or electronic plug-in round case timer. A sealed faceplate allows this timer to be used in harsh environments. Both instantaneous and timed contacts are provided and timers are available for operation on either 120VAC or 240VAC..
