JM Series Meter Counter
>>Overview
JM series electronic counter adopts the single chip micro-processor with excellent performances as its main control component, has the merits of high accuracy, wide counting range, digital display, soft-contact key operating, permanent data retention when power cut, strong anti-disturbance capability, pretty appearance, etc.JM series electronic meter counter can be used in the industries of packing, printing, textile, papermaking, petroleum, chemical engineering, metallurgy, etc, operating for meter counting display and alarm, or control of film, fabric and wire stock.
>>Features
Adopt the micro-computer as the main control component. The functions are strong and the accuracy is high.Adopt the E2PROM to hold the data in credibility and permanence.Adopting the optimized design with electromagnetism compatibility, so the anti-disturbancecapability is strong.>>Specifications
| Model | Range of counting | Function | Output power supply | Appearance size (H×W×L) | Size of mounting hole (H×W) |
JM72S JM48S JM20S JM80S | 0-999999and 0-9999.9 selected by pressing key 0-999999and 0-99999.9 selected by pressing key | with pre-setting,control output type,output mono- stable time delay keeping data/not keeping data when power cut,counting frequency,step,range,etc are selectable | 12VDC/30mA 12VDC/20mA | 72× 72×75 48×48×85 36×76×100 80×160×80 | 68×68 45×45 33×73 76×152 |
>>Technical Parameters and Functions
| Mounting kind | Panel mounting kind or socket mounting kind |
| Selecting of counting kind | 1.when the meter counting value increases to its set-point,the contact output is produced and the counting keeps on. 2.when the meter counting value increases to its set-value,the contact output is produced and the counting close off. 3.when the meter counting value increases to its set-value,the counting keeps on and resets automatically at its contact output with a mono-stable delay. 4.when counting value increases to its set-value,the counting closes off and resets automatically output with a mono-stable delay. |
Contact capabiltiy of the control output | 3A/250VAC(resistance load) |
| The range of step length of meter counting | 0.0001-1.0000m and resolving is 0.1mm.The step length is the length occupied by one pulse. |
| Holding/not holding data is selectable when power cut,the retention data time: | >10years |
| Counting frequency | high speed is 1000 times/s,low speed is 30 times/s(Signal duty ratio is 1 :1)(Selected by key pressing) |
| Input signals and the frequency ought to be selected | 1.Contact signal:For relay,distance switch,microswitch,the frequency should be selected low speed(30times/s) when the signal duty ratio is1:1. 2.Non-contact signal:For approach switch,photoelectric switch ,etc, the frequency can be selected of either high(1000 times/s)or low(30 times/s) according to requirement. 3. Pulse signal:For TTL circuti and so forth (low level VL=0-1.3V, high level VH=4.5-30V). the frequency can be selected of either high (1000 times/s) or (30 times/s) according to requirement. |
| Input impedance of signal | 5kΩ |
| Reset(clear to zero) kind | The values of display and control output all reset at same 1.Reset with reset(clear to zero)key on the plate(only for the counting statue) 2.Reset with the terminals(make short of the RST and COM pins) 3.Local automatic reset with mono-stable delay:0.1-9.9s is selectable. |
| Power supply | 220VAC+10%/-15% 50Hz±2% |
| Power consumption | ≤5VA |
| Operating environment | temperature 0-50°c, relative humidity≤85% |
