AS-BDAU-204是一款由施耐德电气制造的高性能模拟输入模块,以下是该产品的详细情况:
一、基本属性
品牌:施耐德(SCHNEIDER)
类型:模拟输入模块
颜色:黑色
规格:40*50或12*12*12(根据不同描述,可能存在规格上的差异,需具体确认)
二、技术特点
通道数:具有四个通道,且没有光隔离。
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。
配合设备: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。
配置与输出:每个通道均可独立配置,以提供电压或电流环路输出。设计用于控制可调频率驱动器、定位阀、阻尼器等设备。
电源需求:为了正常工作,模块需要来自外部电源(250mA 24VDC)的供电。当不使用外部电源时,模块从内部总线获取电源但会给出错误的读数。
三、指示灯与检测功能
故障指示:模块前面有一个琥珀色LED,闪烁时表示模块故障。
就绪指示:模块前方顶部的绿色LED表示模块准备就绪。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。
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。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)。
AS-BDAU-204 is a high-performance analog input module manufactured by Schneider Electric.Here are the details of the product:
1.Basic attributes
Brand:SCHNEIDER
Type:Analog input module
Color:Black
Specifications:40*50 or 12*12*12(depending on the description,there may be differences in specifications,which need to be confirmed)
2.Technical features
Number of channels:It has four channels and no optical isolation.
A/D conversion:It performs dual slope integral A/D conversion and can convert analog valuesinto 12-bit digital values.
Matching equipment:It can be used with two-wire±500mV sensor field units or PT100 four-wire resistance temperature detector field devices.
Configuration and output:Each channel can be independently configured to provide voltage or current loop output.Designed to control adjustable frequency drives,positioning valves,dampers and other equipment.
Power requirements:In order to work properly,the module requires power from an external power supply(250mA 24VDC).When no external power is used,the module draws power from the internal bus but gives erroneous readings.
3.Indicator and detection functions
Fault indication:There is an amber LED on the front of the module,which flashes to indicate a module fault.
Ready indication:The green LED on the top of the front of the module indicates that the module is ready.When data is sent through the channel,the green LED on each channel will remain on or flash rapidly.
Open circuit detection:It has an open current loop(broken wire)detection function and issues a warning through LEDs and accessible registers.The red LED on each channel indicates that an open current loop(broken wire)or high loop impedance(>500Ω)is detected.
