【English Version】
JDM12A Electronic Preset Counter is an intelligent counting device specifically designed for industrial automation scenarios. Utilizing microprocessor control technology, it delivers precise and reliable counting performance. Equipped with a high-sensitivity signal reception module, the product supports multiple sensor input modes including photoelectric, proximity switches, and mechanical contacts, catering to diverse industrial counting requirements.
Featuring a 1.8-inch high-brightness LED display, the device offers preset value functionality and power-off memory mode. Users can easily set target values through panel buttons. When the actual count reaches the preset value, the system automatically triggers relay output signals with optional audible/visual alarms. Specially designed anti-interference circuits effectively resist electromagnetic disturbances in industrial environments, ensuring stable operation under challenging conditions including dust, oil contamination, and vibrations.
Core functions include: Bidirectional counting mode (freely switchable between addition/subtraction), cumulative data storage (supports up to 999,999 counts), adjustable response time (5ms-200ms), and multi-channel signal parallel processing. The flame-retardant engineering plastic housing with IP54 front panel protection makes it suitable for industrial applications requiring precise counting, such as automated production lines, packaging machinery, textile equipment, and stamping presses.
Humanized design elements include real-time count display, data reset, and parameter lock functions. Sealed button structures prevent accidental operation and liquid ingress. With compact dimensions (48×48×78mm), the device allows for space-efficient embedded installation. Rear-mounted DIN rail clips and wall-mounting holes provide flexible installation options to meet various on-site requirements.
