Introduction to JC20S Electronic Counter

The JC20S is a high-performance preset electronic counter featuring microprocessor control technology, with wide counting range (0-999999), clear digital display and user-friendly operation. It reliably records pulse signals and displays real-time values, equipped with power-off data retention function to prevent data loss. The intuitive panel layout ensures quick mastery of operational logic. 313

Key Features

This counter supports both increment/decrement modes with max 5000 counts/sec (high-speed mode), compatible with contact signals, non-contact sensors (e.g. proximity switches) and TTL pulses. The tactile buttons allow flexible preset value configuration, while four output control modes (continuous counting, stop counting, auto-reset delay, etc.) meet diverse automation needs. Industrial-grade anti-interference capability and 0~50℃ operating temperature ensure reliability. 516

Applications

Widely used in packaging, printing, textiles, papermaking, petrochemical and metallurgical industries for production line counting, equipment rotation monitoring and material length measurement. Typical scenarios include real-time product counting on automated packaging lines or precise fabric length control in textile machinery. Modular design supports both panel-mount and socket installation. 1014

Design Highlights

Features dual-row LED display for clear visibility, rugged housing and ergonomic key layout. Low-power circuitry (≤4.5VA) integrates 12VDC sensor power supply. Three reset methods (manual button, terminal trigger, monostable delay) provide operational flexibility. The compact 36×76mm front panel suits standard industrial control cabinets. 615
