Microprocessor Based Solid State Timer / Counter

Model : CX312A6

Maker : Eagle Signal Controls

Descriptions :

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.

- Keypad lock function allows viewing of setpoint, but does not allow unauthorized changes
- 4 1/2 digit (19999) liquid crystal display - .5 inch high digits
- Annunciators (right of the display) flash to indicate timing or counting
- Two form C instantaneous contacts and two form C programmed contacts
- Five time ranges from 19.999 sec. to 199 hr.: 59 min.
- Three count rate input rate speeds are programmable with a max. count display of 19999 - can be extended via count
   input scale factor
- 24, 120, or 240 VAC operations
- Count input available for 120 volt AC or low voltage AC/DC  operations
- When programmed as timer, count input circuit serves as time inhibit (without resetting the unit)
- Non-volatile memory data retention
