Product Introduction of SK-404 Electronic Counting Controller

The SK-404 is an industrial-grade preset counter designed for automation control systems. Key features include: 1) Four-channel independent setting with relay outputs, allowing customized actions like equipment shutdown or valve control upon reaching preset values; 2) High-speed counting capability up to 700Hz with 9999 counting range and decimal point display; 3) Universal input compatibility supporting 5V+ pulse signals from proximity switches, photoelectric sensors (GZ-6C/GZ-20C series) and Hall effect devices (HJ-1BD); 4) Robust construction with LED display and contactless logic circuits ensuring reliable operation in harsh industrial environments. The unit operates on 220V AC power while providing 12V DC supply for sensors, with protection against voltage fluctuations (±15%). Typical applications cover packaging machinery, textile production, metal processing and other scenarios requiring precise length measurement or quantity control.22124

技术参数与设计特点

该控制器采用无触点开关电路设计，具备85%湿度耐受能力，输入波形适应任意脉冲形态。其模块化结构包含：1）主控模块采用抗干扰设计；2）显示模块采用高亮度红色LED；3）输出模块配置4个独立继电器（触点容量5A/250V AC）；4）电源模块集成过压保护。人机交互方面，产品提供直观的预置值设定按钮和运行状态指示灯，维护人员可通过面板快速进行参数调整。特别适用于需要多阶段控制的场景，如当计数达到第一预设值时触发报警，达到第四预设值再执行停机操作的分级控制流程。21721

Application Scenarios and Advantages

In wire and cable production lines, the SK-404 demonstrates exceptional performance in high-speed length measurement, achieving millimeter-level precision when paired with rotary encoders. For packaging applications, its multi-stage control function enables automated batch counting - triggering separator activation at preset quantities (e.g. 100/500/1000 pcs). Compared with conventional counters, the product offers: 1) Wider temperature adaptability (-10~40°C); 2) Lower maintenance requirements due to solid-state design; 3) Flexible input/output configuration supporting various industrial sensors and actuators. The compact panel-mounted design simplifies integration into existing control panels without requiring additional programming devices.3717
