1.High performance 2.Manufacture 3.72*72* / 48*48 / 36*76 / 80*160 Min order: 5 piese

>>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.

>>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 signal5kΩ 
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.
