MTL4549Y 安全电隔离器
MTLx549接受来自安全区控制器的4/20mA浮动信号，以驱动2个电流/压力转换器(或任何其他负载高达800Ω)在危险区域。对于HART阀门定位器，该模块还允许数字通信信号的双向传输。具有回读功能的过程控制器可以检测现场接线中的开路或短路:如果发生这种情况，进入终端的电流下降到预设水平。MTL4549C和MTLx549Y与MTLx549非常相似，除了它们只提供开路检测(即。无短路检测)。
•标准3端口隔离
•最高的模块/通道封装密度
•低功耗
•快速安装和释放机构
•多通道I/O模块
•折线监控
•兼容之前的MTL隔离器范围的可插拔更换
•在功能安全应用中评估的各种型号
MTL4549Y 安全电隔离器
The MTLx549 accepts 4/20mA floating signals from safe-area controllersto drive 2 current/pressure converters (or any other load up to 800Ω) ina hazardous area. For HART valve positioners, the module also permitsbi-directional transmission of digital communication signals. Processcontrollers with a readback facility can detect open or short circuitsin the field wiring: if these occur, the current taken into the terminalsdrops to a preset level. The MTL4549C and MTLx549Y are very similarto the MTLx549 except that they provide open circuit detection only(i.e. no short-circuit detection).
• 3-port isolation as standard
• Highest module/channel packingdensities
• Low power dissipation
• Quick install and release mechanism
• Multi-channel I/O modules
• Broken line monitoring
• Compatible with preceding MTL isolatorrange for pluggable replacements
• Various models assessed for use inFunctional Safety applicatons
