欧姆龙时间继电器选型

欧姆龙继电器选型办法一、外形、设备办法、设备标准欧姆龙继电器的外形、设备办法、设备标准种类很多，用户有必要按整机的具体需求，提出具体的设备面积，容许继电器的高度、设备办法、设备标准。

这是挑选继电器首要要考虑的疑问。

以下几个疑问，选用时应予以留神：(1).对于PC板式引出脚；脚间隔大都为2.54×n(n=1、2、3……，以下同)，如JZW5；也有2.5n，如JZG2-2/B；也有不符合标准间隔的继电器，如MR72。

引出脚的长度一般为3.5。

(2).引出脚的可焊性、继电器的抗焊接热、引出脚相对底座的不垂直度等应有严峻的需求。

(3).快联接式继电器；快联接引出脚一般有250#(6.35×0.8)、187#(4.75×0.5)2种。

这类引出脚要分外留神插拔力需求，250#引出脚：拔力矩十kg.cm；187#引出脚：拔力矩5kg.cm。

二、输入参量纷歧样种类的输入参量，是挑选欧姆龙继电器类型的首要依据。

多见的输入参量的种类有：(1).交流输入参量。

当输入参量为交流电压(电流)时，应选用交流继电器。

选用这一类型的继电器，应留神以下几个疑问：交流频率----交流继电器输入电压(电流)的频率一般为50HZ，或60HZ。

由于二者线圈的感抗纷歧样，吸动电压有明显差异。

合同中应予注明。

环境温度----交流继电器由于存在涡流损耗、磁滞损耗，继电器的温升较高，一般为70℃到80℃。

工作环境温度不宜过高，最好为40℃到65℃，判定环境温度的核算公式：t1≤t2-t3-150C；注：t1：继电器最高环境温度，0C；t2：漆包线、绝缘资料最高容许长时刻工作温度0C(B 级为1300C；F级为1550C)t3：继电器均匀温升，0C。

接近开关是一种无需与运动部件进行机械直接接触而可以操作的位置开关，当物体接近开关的感应面到动作距离时，不需要机械接触及施加任何压力即可使开关动作，从而驱动直流电器或给计算机（plc)装置提供控制指令。

接近开关是种开关型传感器（即无触点开关），它既有行程开关、微动开关的特性，同时具有传感性能，且动作可靠，性能稳定，频率响应快，应用寿命长，抗干扰能力强等、并具有防水、防震、耐腐蚀等特点。

产品有电感式、电容式、霍尔式、交、直流型。

接近开关又称无触点接近开关，是理想的电子开关量传感器。

当金属检测体接近开关的感应区域，开关就能无接触，无压力、无火花、迅速发出电气指令，准确反应出运动机构的位置和行程，即使用于一般的行程控制，其定位精度、操作频率、使用寿命、安装调整的方便性和对恶劣环境的适用能力，是一般机械式行程开关所不能相比的。

它广泛地应用于机床、冶金、化工、轻纺和印刷等行业。

在自动控制系统中可作为限位、计数、定位控制和自动保护环节等。

Supply 90% to 110% of the rated voltages (at 12 VDC: 95% to 110%).Do not leave the H3YN in time-up condition for a long period of time (for example, more than one month in any place where the ambient temperature is high), otherwise the internal parts (aluminum elec-trolytic capacitor) may become damaged. Therefore, the use of the H3YN with a relay as shown in the following circuit diagram is rec -ommended to extend the service life of the H3YN.MY RelayH3YN The H3YN must be disconnected from the Socket when setting the DIP switch, otherwise the user may touch a terminal imposed with a high voltage and get an electric shock.Do not connect the H3YN as shown in the following circuit diagram on the right hand side, otherwise the H3YN’s internal contacts dif fer-ent from each other in polarity may become short-circuited.CorrectIncorrectUse the following safety circuit when building a self-holding or self-resetting circuit with the H3YN and an auxiliary relay , such as an MY Relay, in combination.Auxiliary relay:MY Relay: H3YN In the case of the above circuit, the H3YN will be in pulse operation.Therefore, if the circuit shown on page 11 is used, no auxiliary relay will be required.contact may become damaged.Be careful not to apply any voltage to the terminal screws on the back of the Timer. Mount the product so that the screws will not come in contact with the panel or metal parts.Do not use the H3YN in places where there is excessive dust, corro -sive gas, or direct sunlight.Do not mount more than one H3YN closely together , otherwise the internal parts may become damaged. Make sure that there is a space of 5 mm or more between any H3YN models next to each oth -er to allow heat radiation.The internal parts may become damaged if a supply voltage other than the rated ones is imposed on the H3YN.Precautions for VDE ConformanceThe H3YN as a built-in timer conforms to VDE 0435/P2021 provided that the following conditions are satisfied.HandlingDo not touch the DIP switch while power is supplied to the H3YN.Before dismounting the H3YN from the Socket, make sure that no voltage is imposed on any terminal of the H3YN.WiringThe power supply for the H3YN must be protected with equipment such as a breaker approved by VDE.Only a load with basic isolation can be connected to the output con -tact. The H3YN is a model with basic isolation. Therefore, the H3YN and the load will ensure reinforced isolation, thus meeting VDE standards.Insulation requirement:Overvoltage category II,pollution degree 2(with a clearance of 1.5 mm and a creep -age distance of 2.5 mm at 240 V AC)Output terminals next to each other on the H3YN-4, H3YN-41,H3YN-4Z, or H3YN-41-Z must have the same electric potential.OMRON CorporationSupervisory Control Devices Division 28th Fl., Crystal T ower Bldg.,1-2-27, Shiromi, Chuo-ku,Osaka 540-6028 JapanPhone: (81)6-949-6035 Fax: (81)6-949-6069ALL DIMENSIONS SHOWN ARE IN MILLIMETERS.To convert millimeters into inches, multiply by 0.03937.
