The CX200 and CX300 are microprocessor based timer/counter housed in a standard 15 terminal CYCL-FLEX® plug-in case. Time or count operation, time range, and standard or reverse start operation is selected by 7 miniature rocker switches located inside the unit housing. Time or count setpoints are entered into the unit using a sealed membrane keypad on the front of the unit. Each digit in the setpoint is individually increased or decreased by pressing the appropriate keypad switch.
Time or count setpoint and progress is displayed on the front of the unit by a 4 1/2 digit liquid crystal display with .5 inch digits. Time or count subtracts from the setpoint and the output changes state at zero. Operational mode annunciators also appear in the display area on the front of the unit. The mode annunciator flashes when the unit is timing or counting.
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 CX series has 2 relay outputs,; 2 form “C” instantaneous contacts, and 2 form “C” programmed contacts. The relays are socket mounted for easy replacement. Outputs can be programmed to operate in one or four lead sequences
