ESD输入/输出信号要求的内容,过于专业,高人辛苦下!? 2.2.3.1 analogue inputs ||模拟量输入 4-20 ma, two wire circuit, powered by system galvanic isolation from the system potential isolation between channels ||4-20ma,两线制,系统供电 ||与系统间电流隔离 ||通道间隔离 2.2.3.2 binary inputs ||二进制输入(估计就是开关量输入) galvanic isolation from system, potential isolation between channels. dry contact 24v dc, powered by esd system. ||与系统间电流隔离 ||通道间隔离 ||干触点 直流24v,esd系统供电 2.2.3.3 binary outputs ||二进制输出 (估计就是开关量输出) dry contacts to subsystem, powered by subsystem. potential isolation from system, potential isolation between channels. voltage 24 vdc (others to be specified). power 2w, resistive and inductive load (other to be specified) ||干触点输出到子系统,由子系统供电。 ||与系统间隔离,通道间隔离。 ||24v 直流电压(其他规格必须指明) ||电源功率2w,电阻负载和感性负载(其他规格必须指明) 注意: potential isolation:具体是什么隔离,不太清楚。没有查到。 others to be specified:如果出现在选型手册上可能是指:其他规格为非常规配置,需要定制所以订货时需要额外说明。如果出现使用手册,可能是说:没有标注就默认(比如24v),如果是其他规格会有明示。 查看更多
炉子点火中的prove是什么意思? the main burner is proven 这个主燃烧器可以被证实是点着火的了。 the flame scanner does not activate the flame-proved light,如果这个火焰扫描器没有被这个已经被证实点着的火焰起动, 猜的。仅供参考查看更多
