JC Series Electric Counter – User Manual
General Description
JC series electronic counter provides excellent performance by
using the single chip micro-processor with high accuracy, wide
counting range, digital display, soft contact operating key, data
protection during blackout, strong anti-disturbance capability,
modern design of appearance, etc.
JC series electronic counter can be used in many industrial
applications such as packaging, printing, pharmacy, food, textile,
papermaking, ceramic, petroleum, chemical engineering, metallurgy,
etc. It can also display and control other parameters like rotating
revolution and length.

5.
Input signals and the frequency options:
⑴
.Contact signal
：
For relay, distance switch, micro switch, the
frequency should be set to low speed (30 times/s) when the signal
duty ratio is 1:1.
⑵
.Non-contact signal
：
For proximity switch, photoelectric switch,
ect, the frequency can be set to either high (1000 times/s) or low(30
times/s) according to requirement when the signal duty ratio is 1:1.
⑶
.Pulse signal: For TTL circuit and impulse voltage (low level VL
=0~1.3V, high level VH=4.5~30V). The frequency can be set to
either high (1000 times/s) or low (30 times/s) according to
requirement.
6.
Modes for control output
mode: When the meter counting value reaches its preset value, the
output contact is emitted and continue counting.
mode: When the meter counting value reaches its preset value, the
output contact is emitted and counting stops.
mode: When the meter counting value reaches preset value, display
is reset to zero automatically and meter counting repeats, and the
control contact is activated until the mono-stable time is elapsed.
( R)
mode: When the meter counting value reaches its preset
value, counting stops ,control contact acts as output, the control
contact is activated until the mono-stable time is elapsed
，
display
is reset to zero automatically and meter counting repeats.
