JDM11-5A

Product overview:

JDM11-5 series digital preset counter can be connected or disconnected according to preset number. It adopts single chip microcomputer program control, digital switch settings, high brightness LED display, counting signal photoelectric clumsy, with strong anti-interference, accurate counting, durable and other characteristics; and with all kinds of sensors such as photoelectric switch, proximity switch. Dry reed, micro-switch, magnetic switch, solid-state components and all kinds of relays, switch contact matching, widely used in printing, packaging machinery, textile machinery, plastic rubber machinery, food machinery, pharmaceutical machinery, photosensitive equipment, wire and cable equipment, all need to automatically detect the number of times, length, revolution Field cooperation counting automatic control.

Functional characteristics:

1. Five-bit high brightness LED display, five-bit preset switch setting, counting signal photoelectric isolation, strong anti-interference, accurate counting, durable. The input of pulse signal is compatible with the counting of contact signal input, and has DC12V power supply at random.

Out for sensor use, can be photoelectric switch, proximity switch, reed, micro-switch, magnetic switch, solid-state components and various relays, switch contacts match.

3. fully functional, reversible A, B, C counting mode, switch through switch, you can choose.

Different counting modes make it more suitable for various occasions.

4. with power off memory, built-in nickel cadmium battery, battery life for more than five years.

Main technical parameters:

Rated power supply voltage: AC110V, 220V, DC12V and 24V.

Power consumption: less than 3W.

Reset mode: manual reset, signal input reset and power off reset.

Output relay life: reliable working 500 thousand times under rated load.

Working environment temperature: -10 ~ +50 degree C (no condensate).

Counting error: no more than 1 pulses.

Working voltage range: rated voltage 85-110%

Count input:

1. Pulse Input: Sensor signals, such as photoelectric switches, proximity switches, etc., are implemented from high level to low level, where UH = 5-30V, UL = 0-2V.

2. Contact input: micro-switch, reed, relay contacts, etc., in the case of frequency not exceeding 10HZ.

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.
