The CX300 is a microprocessor based timer/counter housed in a standard 15 terminal CYCL-FLEX plug-in case which allows easy removal for programming changes and replacement. Time or count operation, time range, and the type of start input switch operation are programmed with 7 miniature rocker switches located inside the unit housing.
The front panel of the CX300 is a sealed membrane keypad which provides excellent protection for most industrial environments. The time or count setpoint is entered using the increment and decrement keys for each digit position. The SET and ENT keys provide access to the setpoint, as well as to the front panel programmable software functions. These programmable functions control the pulse output length, setpoint to zero or zero to setpoint cycle progress indication, and count input scale factor. The software programming functions are indicated by prompts to help the user program these functions without the need for written instructions.
The timer/counter has a keypad lock function that allows viewing of setpoint, but does not allow unauthorized changes. It's 4.5 digit (19999) liquid crystal display has 0.5 inch tall digits which allow for clear and unmistakable numbers. It also has annuciators (right of the display) that flash to indicate timing or counting. The counter/timer also has 2 form C instantaneous contacts and 2 form C programmed contacts. You can program upto 5 time ranges from 19.999 seconds to 199 hours and 59 minutes. The CX300 also has three count input rate speeds which are programmable with a maximum count display of 19999. This can be extended with a count input scale factor. It runs off of 24, 120, or 240VAC operations. There are counting inputs available for the 120VAC or low voltage AC/DC operations. When programmed as a timer, the CX300's count input serves as a time inhibit without resetting the unit.
