JDM-14/电子预置计数器JDM14
产品概述
JDM14电子预置计数器是一款工业自动化领域广泛应用的智能计数设备，采用微电脑处理器为核心，配合高精度电子电路设计，能够实现稳定可靠的脉冲信号计数功能。该产品具备1-9999的宽范围计数能力，支持正/倒计数模式切换，并采用0.3英寸LED数码管清晰显示实时数值。内置可充电镍氢电池可确保在意外断电时完整保存计数数据，实现长达10年的停电记忆功能。其标准面板尺寸（48×48mm）适合各类工业控制柜安装需求，操作界面简洁直观便于快速设置。1611
核心功能特性
JDM14提供多模式信号处理能力，可兼容机械触点、电平脉冲（DC4-30V有效）及各类传感器（光电/接近/霍尔开关）输入，通过拨码开关可灵活设置N/F/R三种输出制式。产品内置DC12V/30mA辅助电源输出端子，可直接为外接传感器供电。具备25次/秒（低频）和250次/秒（高频）两种计数速度模式，通过端子短接即可切换。特殊设计的抗干扰电路使其在10-55Hz振动环境下仍能保持稳定工作，符合工业场景的严苛要求。101214
应用场景说明
This preset counter is particularly suitable for production line monitoring, material quantity statistics, and periodic operation control in manufacturing environments. Its auto-reset function and preset value triggering mechanism make it ideal for punch press stroke counting, packaging equipment batch control, and conveyor belt product tracking. The dual-input design (CP1/CP2) allows connection with both mechanical switches and solid-state sensors, providing flexibility for different automation scenarios. Clear LED display ensures real-time visibility of counting status even in low-light workshop conditions. 6818
Technical Specifications
The JDM14 features a wide operating voltage range (AC/DC 100-240V) with optional customized voltage versions. It achieves counting accuracy of ±1 pulse through optoelectronic isolation technology. The 4.7KΩ high-impedance input circuit effectively suppresses signal noise. Housing dimensions of 104×52×114mm with front panel IP40 protection level suit most industrial control panels. Relay output contacts support 5A/250V AC resistive loads, capable of directly driving small motors or solenoid valves. User-adjustable parameters include preset value, counting direction (up/down), and output action delay (0-9.9s). 121314
操作与维护指南
Operation involves three simple steps: preset target value via dial switches, select counting mode via function keys, and connect signal sources to designated terminals. The product requires minimal maintenance - occasional dust removal and terminal tightness checks are recommended. Built-in self-diagnosis function alerts users to abnormal input signals through display flashing. For first-time users, connection diagrams are clearly marked on the side panel showing typical wiring configurations with sensors and control devices. 71019
