羿司罗4843DC24V继电器的文字标号是什么?(国标)是KM,还是J,还是? -
詹选牧18450135534 ______ 继电器通用代号为K,可以加辅助代号,如KA.KM表示“接触器”.也不要用J,这是过去的拼音代号,现在与IEC接轨,统统用英文字母了.至于24VDC,那是继电器种类型号包含的内容,与图中代号无关 dc24v继电器,是由固定铁芯、动铁芯、弹簧、动触点、静触点、线圈、接线端子和外壳组成.线圈通电,动铁芯在电磁力作用下动作吸合,带动动触点动作,使常闭触点分开,常开触点闭合;线圈断电,动铁芯在弹簧的作用下带动动触点复位.触点又分为常闭和长开两种,一个公共点.

羿司罗4843继电器编号的数字含义是什么?急~谢谢~ -
詹选牧18450135534 ______ 每个厂家的数字编号的意义都不太一样.以某厂的 XX-112D3M 大概是:XX是指产品系列,1:一组接点;12:12VDC的coil; D:标准品,3:是指使用的材料,M:是常开型继电器

羿司罗4843继电器的脚为什么用30、85、86、87来表示 -
詹选牧18450135534 ______ 86.85是继电器线圈的引出脚. 30与87a常闭合.当86.85两端有直流电压时30与87a断开,与87合.继电器是一种电控制器件.它具有控制系统(又称输入回路)和被控制系统(又称输出回路)之间的互动关系.通常应用于自动化的控制电路中,它实际上是用小电流去控制大电流运作的一种“自动开关”.故在电路中起着自动调节、安全保护、转换电路等作用.

羿司罗4843哪个是继电器的符号啊!? -
詹选牧18450135534 ______ K是继电器线圈,K-1是继电器的常闭触点,K-2是继电器的常开触点

羿司罗4843中间继电器用什么英文字母代表?一般常用的“欧姆龙”4P 线圈为220V的中间继电器用什么表示? -
詹选牧18450135534 ______[答案] 欧姆龙的继电器型号很多,最好把你要查询的继电器型号规格写全,否则不好查询.

羿司罗4843时间继电器什么字母表示
詹选牧18450135534 ______ 时间继电器的文字符号为——KT (a)表示通电延时线圈 (b)表示断电延时线圈 (c)表示瞬动触点 (d)表示通电延时闭合常开触点 (e)表示通电延时断常闭触点 (f)表示断电延时断开常开触点 (g)表示断电延时闭合常闭触点

羿司罗4843电工里的字母都代表什么?越多越好 -
詹选牧18450135534 ______ U电压 I 电流 R 电阻 Z总电阻 C表示电容 S 表示视在功率 W表示瓦特 1千瓦=1小时1度电等等.AC 交流电DC 直流电FU 熔断器G 发电机M 电动机HG 绿灯HR 红灯HW 白灯HP 光字牌K 继电器KA(NZ) 电流继电器(负序零序)KD 差动继电器KF 闪光...

羿司罗4843继电器符号 -
詹选牧18450135534 ______ 热继电器符号是FR,其工作原理是当通过热继电器电流过大时,其控制机构上的弹簧片因为电流大过额定电流而瞬间发热产生变形,将其主电路断开,以保护工作机构的一种电子器件!
