MTL安全栅
主要特点
13.符合FSM认证标准（MTL FSM), MTL是过程仪表设备供应商中第一家取得该认证的厂家。对于安全完整性等级(SIL)认证是对整个回路的考虑而不只是某个部件，而对于具体的部件，不同的计算方式得出的SIL等级也不同，通常需要提供基本数据而不是SIL等级给ESD厂家计算整个回路的等级。（SIL)

主要特点
17. 安全栅和底板密集设计，减轻了重量，提高了安装密度。安全栅厚度仅16mm，底板有4、8、16、24个组件等多种选择。
客户化解决方案
主要特点
安全栅底板通过多芯插头及电缆直接与部分DCS I/O卡件连接，省去DCS 端子板及传统的由安全栅到端子板的点与点连接线，从而节省了机柜空间，简化了工程量，减少了人为错误，降低了工程费用。

MTL5500系列安全栅说明书

Key features of the MTL5500 Series are ease of application, high operational integrity and reliability, and low installed cost. Full 3-port isolation between the input, output and power supply circuits eliminates the need to think about relationships to earth, makes system hook-ups easier to arrange, and allows hazardous-area circuits to be left floating or earthed at any one point.
Where space is at a premium, high packing densities are essential. With a unit width of 16mm, and with many units providing multiple channels (and hence a lower cost per channel), the MTL5500 Series takes up a minimum of space – which leaves more for other process control equipment. Where older installations are being updated, there may be a need for more channels – but within the existing space. The MTL5500 Series can provide the answer, fitting extra units and channels into a space formerly occupied by bulkier isolators.

mtl安全栅

mtl安全栅
MTL安全栅（MTL Safety Barrier）是一种用于防爆电气设备
的安全措施，可确保在爆炸危险环境中使用电气设备时的安全性。

MTL安全栅的主要功能是将非安全信号（非防爆区域）转换
为安全信号（防爆区域），从而保护设备和人员免受爆炸和火灾的威胁。

它可以用于防爆区域的仪表、开关、传感器等设备的安全隔离和防护。

MTL安全栅的工作原理是通过使用阻挡电流的方式，将输入
信号转换为安全的输出信号。

它通过限制电流和电压的传输，防止火花或电弧的形成，从而降低了爆炸的风险。

MTL安全栅一般由两个部分组成：输入模块和输出模块。

输
入模块将非安全信号输入，输出模块将转换后的安全信号输出。

这两个模块之间通过隔离电路实现电流和电压的隔离，并确保在非安全区域的故障不会传导到防爆区域。

MTL安全栅具有多种特点和优势，如可靠性高、安装简便、
体积小等。

它能够适应各种恶劣环境，如湿度、温度、振动等，并具有一定的耐腐蚀性能。

另外，MTL安全栅还能够进行自
我监测和故障检测，以确保设备的正常运行和安全性。

总之，MTL安全栅是一种重要的防爆电气设备，它能够有效
地保护设备和人员免受爆炸和火灾的威胁。

在危险环境中使用
MTL安全栅可以提高工作安全性和生产效率，为工业生产提供保障。

The kits covered are the MK02, MK05, MK12 and MK20 for mounting up to 2, 5, 12 and 20 barriers respectively. For detailed information about installation requirements for MTL700 range barriers, refer to INM700, ‘Instruction Manual for MTL700 range shunt-diode safety barriers’. The mounting kits contain all the accessories needed to mount the corresponding number of MTL700 range barriers, and provide facilities for earthing, terminating cable screens and tagging (tagging facilities are notprovided with MK02 kits). Sections 2 and 3 list the parts forming each kit and provide the necessary assembly instructions.2.2 Assembly instructions for MK02 kitsUse the four self-tapping screws (3) and M4 washers (4) to attach the mounting bracket (1) to the insulating block (2) through the four M4 holes.The insulating block (2) is provided to keep the IS earth (terminated on the mounting bracket (1)) separate from a structural earth but, if the mounting surface is insulated, then the insulating block may not be necessary.Use the 4mm terminal clamps (5) to connect the IS earth and terminating cable screens to the mounting bracket.2 MK02 kit2.1 MK02 parts listItem DescriptionQuantity1Mounting bracket 12Insulating block13 3.9 x 9.5 self-tapping screws 44M4 washers45Terminal clamp (4mm)313452MK02 - Assembly diagram3 MK05, MK12, MK20 kit3.1 MK05 parts listItem Description Quantity1DIN rail (156mm)12Earth busbar (99mm)13Earth rail mounting brackets25Insulating mounting block26Tag label assembly17Black seal18M4 Nyloc nuts49M4 washers411Terminal clamps (16mm)312Terminal clamps (4mm)3 3.2 MK012 parts listItem Description Quantity1DIN rail (246mm)12Earth busbar (200.5mm)13Earth rail mounting brackets24Earth rail (215mm)15Insulating mounting block26Tag label assembly17Black seal18M4 Nyloc nuts49M4 washers410Earth rail clamp211Terminal clamps (16mm)312Terminal clamps (4mm)6 3.3 MK20 parts listItem Description Quantity1DIN rail (388mm)12Earth busbar (316.5mm)13Earth rail mounting brackets24Earth rail (330mm)15Insulating mounting block26Tag label assembly17Black seal18M4 Nyloc nuts49M4 washers410Earth rail clamp211Terminal clamps (16mm)312Terminal clamps (4mm)10Assembly instructions forMK05, MK12 and MK20 kitsNote:The MK05 kit is NOT provided with an earth rail (4) and earth rail clamps (10), so take care to follow the special instructions provided in 3.4.4 rather than 3.4.3 if using this kit.3.4.1L ocate the busbar (2) on the fixing studs of the insulating mounting blocks (5), making sure both blocks face the same way.3.4.2F it the earth rail mounting brackets (3) onto the studs of each mounting block on top of the busbar, and secure using M4 washers (9) and Nyloc nuts (8).3.4.3(MK12 and MK20 only). Fit the earth rail clamps (10) onto the shorter protruding lengths of the earth rail mounting brackets (3). This is the hazardous side of the assembly. Slide the smaller (4mm) terminal clamps (12) onto the earth rail (4) and mount the earth rail onto the earth rail mounting brackets (3) with the earth rail clamps (10). Fit the larger (16mm) terminal clamps (11) ontothe longer protruding lengths of the earth rail mounting brackets (3), two being mounted on one bracket and one on the other. These terminals are used for connecting the IS earth.3.4.4 (MK05 only). Fit the smaller (4mm) terminal clamps (12) onto the shorter protruding lengths of the earth rail mounting brackets (3) and the larger (16mm) terminal clamps (11) onto the longer protruding lengths. In both cases, two are mounted on one bracket and one onthe other. The smaller terminal clamps serve the same purpose as the earth rail and clamps for the MK12 and MK20 while the function of the larger terminal clamps is the same for all three kits.3.4.5To mount the insulating mounting blocks (5), check that the swing nuts forming part of each unit are turned away and locate the units on the DIN rail (1). Tighten the swing nut screws to pivot the swing nuts underneath the edge of the DIN rail, so securing the blocks to the rail.3.4.6 Complete the installation by adding the tagging facilities. First, remove the label to add identification then replace and secure with the clic rivet. Next, clip the tag label assembly (6) onto the installation with the lugs on top of each insulating mounting block (5). Finally, ‘seal’ the tagging information to the installation by fitting the tagging strip seal (7) through the hole in the tagging strip and the vertical slot in the mounting block. The tagging strip can be unclipped from one side only and hinged open to provide access to the mounting studs and terminals of the barriers when required.2INS 701 Rev 3INS 701 Rev 33Eaton Electric Limited,Great Marlings, Butterfield, LutonBeds, LU2 8DL, UK.Tel: + 44 (0)1582 723633 Fax: + 44 (0)1582 422283 E-mail:********************© 2016 EatonAll Rights ReservedPublication No. INS 701 Rev 3 091116 November 2016EUROPE (EMEA):+44 (0)1582 723633********************THE AMERICAS:+1 800 835 7075*********************ASIA-PACIFIC:+65 6645 9864 / 6645 9865************************The given data is only intended as a productdescription and should not be regarded as a legalwarranty of properties or guarantee.

详细资料：
模拟量输入安全栅MTL5544D
用来为危险区域常规的2或3线制4/20mA变送器提供一个全悬浮直流供电，并在另一侧隔离电路中重现相应的电流，从而去驱动安全区的负载。

对于2线制智能变送器，支持叠加到4/20mA回路电流上的数字通讯信号双向通讯。

MTL5500系列在应用层面是万能产品，而且操作简单。

采用技术生产制造，并得到很好的验证。

这些对比的属性来源于进展的MTL 的专门技术在光电隔离器本质安全方面的设计和制造以及MTL为达到所要求的分离和隔离电路在创新技术上的应用。

这个
MTL5500(DIN-rail安装)和MTL4500(底板安装)建议共享一个共同的设计中,不同的只在机械安装和连接方法。

MTL安全栅

品牌:MTLMTL是一家英国知名公司，成立于25年前，它的本质安全栅和隔离栅成为工业标准已有多年。

该公司在工业过程控制，特别是本安领域中一直处于国际领先地位。

MTL产品在质量、可靠性和安全性方面已经成为工业标准，并获得世界上许多权威机构的认证.MTL公司主要生产齐纳栅、隔离栅、多路转换器、显示器和过程I/O，并同DCS公司和系统集成商有紧密的合作，为石油、石化等工厂提供防爆产品。

MTL公司同时也生产防雷击抗浪涌保护器。

在中国，MTL产品已广泛应用于化工及石油化工、水处理、冶金、制药、电力、水泥、纸浆和造纸、公用事业自动化等领域。

MTL700系列实际是一种“工业规格”，产品注意了固定安装和接地排列。

其运用范围包括超电压保护和子系统电源超高保护。

单通道和双通道供用户任意选择MTL702+/705+/706+/707+/707P+/708+/710+/710-/710ACMTL710P+/710P-/715+/715-/715P+/722+/722-/722P+MTL728+/728-/728AC/728P+/729P+/751AC/755AC 等MTL4000系列第三代隔离接口单元为本安电路集成在大/中型过程控制系统装置提供了一个新的思路。

由于该系列产品结构特别小巧。

因此，具有安装密度高的特点，每个组件是借助于由多通路连接器制成的安全区连接件插件在系统地板上的，这是一种既可简化工程又可降低安装维修费用的方法MTL4013/4014/4015/4016/4017/4021/4023/4024/4025MTL4031/4032/4041/4042/4043/4044/4045/4046/4047MTL4053/4061/4073/4081/4215/4216/4220 等MTL5000系列是MTL最新推出的本安隔离栅，使系统布置和安装更为简便，5000系列提供所有通用功能，因此，安装设计简单易行。

MTL5000系列夹紧式安装方法可将其快速装于DIN导轨上，完全是一种工业标准安装系统，安全区和危险区接线采用简单的插入式接线块，电源插头有多种形式，因此，接线快速，减少接线错误，安全使用，排列整齐。
