Feature 1 Widely used in industrial automation control systems. Possess super antiinterference, high reliability 2 JDM116H possess the functions of contact calculation, DC level counting and sensor counting 3 Using mathematical filter counting, accurate counting with wide counting range, the highest count is 999999, and has power failure memory function 4 Widely used in petroleum, chemical, textile, machinery, mining, national defense, agriculture, food, printing and other industries, but for the control of valuable equipment or the occasion where the product is damaged and endanger people safety, please do a secondary protection 5 The sensing distance is 30cm(adjustable), when an transparent/opaque object passes through the sensor, it starts countingItem Type: Digital Display CounterModel: BEM-6H-30C4-L-CTPower Consumption: 10WCounting Range: 1-999999Counting Speed: 10 Times/secWorking Method: Continuous working systemCounting Method: Contact count, level count and sensor countOperating Temperature: -5-45Storage Temperature: -20-70Reset Time: 0.5 SecondsPower Restart: 1 SecondInduction Distance: Approx. 30cm / 11.8in(adjustable)Detection Object: Transparent/opaque objectReset Method: Panel resetCounting Error: 1Data Retention: 10 YearsPower Cord Length: Approx. 1.5meter / 4.9ftSensor Cable Length: Approx. 1.5meter / 4.9ftHow to Use: 1. The contact input should be reliable to avoid malfunction caused by contact bounce.2. Reset Function: Press the panel reset button at any time. The counter returns to the initial state, and the reset time is 0.5 seconds.3. The maximum speed of the calculator is the maximum speed when the duty ratio is 1: 1, and the pulse width of on or off is greater than 50 milliseconds.4. In the control system, the counter control line is wired separately from other power lines; in a strong current environment and the counting terminal wire is long, please use a shielded wire.
