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
產(chǎn)品結(jié)構(gòu)特點
繼電器采用模塊化設(shè)計,電磁系統(tǒng)與觸點機構(gòu)采用拍合式結(jié)構(gòu),確保動作快速可靠。信號指示器采用機械掉牌設(shè)計,具備自保持特性,斷電后仍可持續(xù)顯示動作狀態(tài)。殼體選用阻燃工程材料,符合工業(yè)環(huán)境防護要求,內(nèi)部接線端子采用鍍銀工藝增強導(dǎo)電性能。特別設(shè)計的橫向安裝方式(DX-8G型)節(jié)省控制柜空間,與縱向安裝的DX-8型形成系列化解決方案。透明上蓋配合紅色信號牌形成高對比度視覺提示,便于運維人員快速識別設(shè)備狀態(tài)。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
