JDMS-98A

Structure and uses:

JDMS-58, JDMS-98, JDMS-98A electronic counting controller, is a three-position counter, a six-position accumulative counter, and a delay relay composed of the counting controller assembly. It uses a single-chip microcomputer program control, high brightness LED display, built-in high-capacity rechargeable nickel-cadmium battery, with no mechanical wear, service life. It is suitable for printing, food, chemical, packaging, hardware, machinery and other automated production processes as batch preset counting and total automatic cumulative counting.

Main technical parameters:

Rated supply voltage: AC 24V, 110V, 220V, 380V, DC 24V.

Working voltage range: rated voltage 85-110%.

Counting input mode: photoelectric input.

Counting range:

Batch count: 0-999.

Cumulative count: 0-999999.

Work mode: add count.

Counting error: not counting with + 1 times.

Power consumption: 5W.

Working environment temperature: -10 ~ +50 C

No condensate.

Zero reset mode: manual reset.

Maximum count frequency: 60 times / sec.

Output contacts: a group of normally open normally closed.

Output contact capacity: AC220V 7A (resistive).

Interval delay range: 0.01-9.99 seconds.

Battery life: over three years.

Working principle:

First set the batch number and batch interval time, then turn on the power supply, the counting signal is transmitted by the photoelectric switch input, the batch counter and the cumulative counter count at the same time, when the counting value and the batch counter preset value coincide, the internal implementation of relay suction, output a group of conversion contact signals and a group of 220V power supply, batch refers to When the delay arrives at the preset time, the internal execution relay is released. Like this, the cumulative counter is increased according to the signal transmitted by the photoelectric switch until it reaches 999999, and then counts again from zero. The counting value is maintained by the internal nickel-cadmium battery, and the nickel-cadmium battery is always in the state of automatic charging when the NC controller works. When the next boot is started, such as the original store count.

No need is needed. It should be cleared according to bulk clearing and accumulative clearing buttons.

Note: JDMS-98A type counting control box is new product, set by light touch switch (see instruction manual).
