MTL安全栅? mtl5081 (millivolt/thermocouple isolator):用于热电偶信号,输入输出都为电压信号。mtl5081+热电偶卡件完成对热电偶信号检测。 mtl5082 (resistance isolator):用于热电阻信号,输入输出都为电阻信号。mtl5082+热电阻卡件完成对热电阻信号检测。 在介绍mtl5082 有这么一段英文:the mtl5082 should be considered as an alternative, non-configurable mtl5074, for use in rtd applications where a resistance input is preferred or needed instead of 4/20ma. 意思是:mtl5082 是可以替代mtl5074,不用组态的。众所周知:用组态软件完成mtl5074组态后,mtl5074就可以将热电阻或热电偶信号转换成4-20ma信号。 mtl5074 (temperature converter):mtl5074就可以将热电阻或热电偶信号转换成4-20ma信号查看更多
