Scope of use and product characteristics:

JDM72-4AL type accumulator/preset combination counter is composed of a six-bit accumulator counter, a four-bit preset counter and a suction delay relay. It can turn on or off the circuit according to the preset number. It has the characteristics of high performance, accurate counting and durability, and can be matched with all kinds of sensors such as photoelectric switch, proximity switch, dry reed tube, micro-switch, magnetic switch, solid-state components and all kinds of relays and switch contacts. It is widely used in production line as batch control and cumulative production volume counting. Especially suitable for: printing, packaging machinery, textile machinery, plastic and rubber machinery, food machinery, pharmaceutical machinery, photosensitive equipment, wire and cable equipment, all need to automatically detect the number of times, length, revolution occasions for batch counting automatic control and cumulative total.

Usage and maintenance:

Please confirm whether the nominal voltage of the counter is in line with the supply voltage before wiring and follow the wiring diagram correctly.

When using proximity switch and photoelectric switch sensor as counting signal source, the sensor whose rated voltage matches the counter output voltage for sensor should be selected.

The contacts of relays, switches and other signal sources used for input counting of contact signals should be reliable and no strong arcing. If the wrong counting is caused by contact jitter, please connect 1-10UF capacitor at the input of the counting.

The number of input terminals must not input voltage higher than DC30V, otherwise the counter will be damaged.
