DX-8G型信号继电器
DX-8G型信号继电器产品介绍(中文)
DX-8G型信号继电器是一种专为直流操作的保护和自动控制装置设计的机电一体化设备,主要用于实现机械保持和手动复归的动作指示功能。该继电器采用电磁式工作原理,当线圈通电时,衔铁吸合带动信号牌落下并闭合触点;断电后通过机械结构保持状态,需手动复位信号牌。其核心特点包括:额定电压覆盖DC12V至220V多档可选,电流规格从0.01A至4A共13种细分型号,可满足不同场景的灵敏度需求。产品采用透明壳罩设计,便于直观观察内部动作状态,支持前/后接线方式(JK-5标准壳体),安装灵活性强。技术参数方面,触点容量在250V/5A直流有感负荷下可达50W断开能力,机械寿命超过5万次操作,动作时间≤30ms,功率消耗低于3W(电压型)或0.3W(电流型)。典型应用于电厂、矿山等工业环境的保护回路中,作为故障指示或状态监测的关键元件。15712
DX-8G Signal Relay Product Introduction (English)
The DX-8G signal relay is an electromechanical device specifically engineered for DC-operated protection and automation control systems, serving as a mechanically latched and manually reset action indicator. Operating on electromagnetic principles, its coil energization drives the armature to drop the flag indicator and close contacts, with the status maintained by mechanical latching until manual reset. Key features include: multi-range rated voltages from 12V to 220V DC, 13 current specifications spanning 0.01A to 4A for precision matching with varied sensitivity requirements, and transparent housing for visual operation monitoring. Compatible with front/rear wiring (JK-5 standard enclosure), it offers flexible installation options. Technical specifications highlight 50W breaking capacity at 250V/5A DC resistive-inductive load, over 50,000 mechanical operations, ≤30ms response time, and low power consumption (<3W for voltage type / <0.3W for current type). Widely deployed in industrial protection circuits such as power plants and mining systems for fault indication and status monitoring applications. 571214
产品结构特点
继电器采用模块化设计,电磁系统与触点机构采用拍合式结构,确保动作快速可靠。信号指示器采用机械掉牌设计,具备自保持特性,断电后仍可持续显示动作状态。壳体选用阻燃工程材料,符合工业环境防护要求,内部接线端子采用镀银工艺增强导电性能。特别设计的横向安装方式(DX-8G型)节省控制柜空间,与纵向安装的DX-8型形成系列化解决方案。透明上盖配合红色信号牌形成高对比度视觉提示,便于运维人员快速识别设备状态。91216
Structural Features
The relay adopts modular design with clapper-type electromagnetic system and contact mechanism ensuring swift and reliable operation. Its mechanical flag indicator features self-latching characteristic that maintains tripped status after power loss. The flame-retardant enclosure meets industrial protection standards, while silver-plated terminals enhance conductivity. The unique horizontal mounting (DX-8G model) optimizes panel space utilization, complementing the vertical DX-8 model for systematic solutions. High-visibility design combines transparent cover with red flag for instant status recognition by maintenance personnel. 121619
