>>Overview
JC Series Electroinc Counter is a high accurate counter, which adopts the single chip micro-processor with excellent performances as its main control component. Is has the advantages of high accuracy, wide counting range, digital display, soft-contact key operating, permanent data retention when power cut, strong anti-disturbance capability, pretty apprarance, etc.
Counter can be used in the industries of packing, printing, pharmacy, food, papermaking, ceramic, petroleum, chemical engineering, metallurgy, etc. operating for counting and display. It can also display and control the rotating revolution, lenth and other parameters.
>>Features
Adopting the microcomputer as its main control component in design. It is considered to replace hardware with software if possible, so that the reliability of the meter is improved obiviously.Adopting the E2PROM to hold the data in credibility and permanence.Adopting the optimized design with electromagnetism compatibility, so the anti-disturbance capability is strong.>>Specifications

>>Technical parameters and Functions
| Mounting kind | panel mounting kind or socket mounting kind |
| Selecting of counting kind | (1)When the counting value increases to its set point,contact output is produced and counting keeps on. (2)When the counting value increases to its set value,contact output is produced and counting closes off. (3)When counting value increases to its set-value, counting keeps on and the meter clears to zero automatically during its contact output with a mono-stable delay. (4)When counting value increases to its set-value , counting closes off and the meter clears to zero automatically during its contact output with a mono-stable delay. |
| Contact capability of the control output | 3A/250VAC (for resistance load) |
| Keeping data/not keeping data is selected when power cut data retention time | >10 years |
| Counting frequency | high speed is 5000 times/s, low speed is 250 times/s (signal duty ratio is 1:1) |
| Input signals and the frequency that ought to be selected | (1)Contact signal:For delay,distance switch,microswitch,the frequency should be selected in low speed(30 times/s) (2)Non-contact signal:For approach switch, photoelectric switch, etc. the frequency can be selected in either high(1000 times/s) or low(30 times/s) according to requirement. (3)Pulse signal:For TTL circuit and so forth(low level VL=0-1.3V, high level VH=4.5-30V). the frequency can select either high(1000 times/s) or low(30 times/s) according to requirement. |
| The input impedance of signal | ≥5kΩ |
| Reset(clear to zero) kind | The values of display and control output all reset at same (1)Reset with the reset(clear to zero)key on the surface panel(only for the counting statue) (2)Reset with the terminals wiring(make short of the RST and COM pins) (3)Local automatic reset with mono-stable delay:0.1-9.9s is selectable (for JC80-Z, this function is without) |
Power supply | 220VAC (+10%,-15%) 50HZ+2%;(special order is required for 24VDC or other voltage) |
| Power consumption | ≤4.5VA |
| Operating environment | temperature 0-50°c ,relative humidity≤85% |
