§ 输入类型: mV, V, mA
§ 采样速率:10采样点/秒
4017亚当模块是用在CEMS烟气在线监测系统预处理单元中,用途是把烟气在线监测系统所监测的SO2、NOx、O2、温度、压力、流速、烟尘、湿度8组份的模拟量转成数字量,给工控机通讯。ADAM-4017是一款16位、8通道的模拟量输入模块,其所有通道上具有可编程输入范围。这些模块在工业测量和监控应用方面是一项极为经济的解决方案。它能够在模拟量输入通道与模块之间提供3000V直流电的光隔绝保护,以避免模块和周边设备被输入线上的高压损坏。ADAM-4017提供信号条件,A/D转换,范围和RS-485数字通信功能。该模块通过在A / D输入和变压器之间提供高达3000伏直流电进行光隔离,防止了设备遭到地面环流和震荡的损坏。ADAM-4017采用一个16位微处理器控制的Σ - Δ转换器,把传感器电压或电流转换成数字数据。然后,数字数据被转变为工程单位。当受到主机提示时,该模块将通过标准RS-485接口向主机发送数据。
