描述
基本信息
品牌：施耐德（SCHNEIDER）
产地：法国
通道数：4个
技术参数
电源需求：需要外部电源供电，如250mA 24VDC，当不使用外部电源时，模块会从内部总线获取电源，但可能会导致错误的读数。
A/D转换：执行双斜率积分A/D转换，能将模拟值转换为12位数字值。
输入范围：可与两线制+/-500mV传感器现场单元或PT100四线电阻温度检测器现场设备配合使用。
开路检测：具有开路电流回路（断线）检测功能，并通过LED和可访问寄存器发出警告。
数据保持：可以配置为在与CPU的通信丢失超过1秒、CPU停止或断电时保持最后一个值。
指示灯说明
琥珀色LED：闪烁时指示模块故障。
绿色LED：模块前方顶部的绿色LED指示模块准备就绪；当数据通过通道发送时，每个通道上的绿色LED将保持亮起或快速闪烁。
红色LED：每个通道上的红色LED表示检测到开路电流环路（断线）或高环路阻抗（>500Ω）。
Basic Information
Brand:Schneider(SCHNEIDER)
Origin:France
Number of Channels:4
Technical Specifications
Power Requirements:Requires external power supply,e.g.,250mA 24VDC.When no external power is used,the module will draw power from the internal bus,but this may result in inaccurate readings.
A/D Conversion:Performs dual-slope integration A/D conversion,converting analog valuesto 12-bit digital values.
Input Range:Compatible with two-wire+/-500mV sensor field devices or PT100 four-wire resistance temperature detectors.
Open Circuit Detection:Features open circuit loop(broken wire)detection,with warnings indicated by LEDs and accessible registers.
Data Retention:Can be configured to retain the last value when communication with the CPU is lost for more than 1 second,when the CPU stops,or during a power outage.
LED Indicators
Amber LED:Flashes to indicate a module fault.
Green LED:The green LED on the top front of the module indicates that the module is ready;when data is transmitted through a channel,the green LED on that channel will remain lit or flash rapidly.
Red LED:The red LED on each channel indicates that an open circuit loop(broken wire)or high loop impedance(>500Ω)has been detected.
