AS-BADU-204 模拟输入模块 该单元有四个通道

Modicon AS-BDAU-204是由施耐德电气制造的模拟输入模块。该单元有四个通道，没有光隔离。它执行多项任务，包括双斜率积分A/D转换，将模拟值转换为12位数字值。这是针对建议的范围完成的。您可以将 Modicon AS-BDAU-204 与两线制 +/- 500 mV 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。这些产品在法国制造，专为物料搬运、包装和纺织机械使用而设计。它们提供MRO电气的2年保修。我们还提供来自其他制造商的I / O模块，如Modicon和ABB。

特征

现场布线

对于 ASBDAU204 配置，使用 60/75 铜 （Cu） 进行电源连接，使用 4.5 英寸磅。固定螺钉的扭矩。为防止现场设备操作出错，请遵循以下准则：

使用屏蔽双绞线电缆（如百通 9418）。

仅在DAU 204上接地每根信号电缆的屏蔽层。在每根信号电缆的另一端，剥离屏蔽层并使其与信号传输线绝缘。

尽可能远离电气噪声源（如电机、变压器、接触器，尤其是交流设备）布线每根信号电缆。

在不同于交流电缆和电源线的导管中布线信号电缆。

如果信号电缆必须穿过交流电缆或电源线，请确保它们以直角交叉。

将现场设备连接到模块时，保持信号传输线的非屏蔽部分尽可能短。

接线端子后，请使用随附的钥匙防止接线端子被意外切换。

优势

Modicon AS-BDAU-204 是一款 4 通道模拟输出模块，设计用于控制可调频率驱动器、定位阀、阻尼器等。每个通道均可独立配置，以提供电压或电流环路输出。

为了正常工作，模块需要来自外部电源（250mA @ 24VDC）的电源。当不使用外部电源时，模块从内部总线获取电源并给出错误的读数。请勿将此模块在机架中未通电。

ASBDAU204 模块具有开路电流回路（断线）检测功能，并通过 LED 和可访问寄存器发出警告。ASBDAU204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。

模块前面有一个琥珀色 LED，闪烁指示模块故障。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。在

电流模式 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）。

Modicon AS-BDAU-204 is an analog input module manufactured by Schneider Electric. The unit has four channels with no optical isolation. It performs A number of tasks, including a double slope integral A/D conversion, which converts analog values to 12-bit digital values. This was done for the scope of the recommendation. You can use the Modicon AS-BDAU-204 with a two-wire +/ -500 mV sensor field unit or a PT100 four-wire resistance temperature detector field unit. Manufactured in France, these products are designed for material handling, packaging and textile machinery use. They come with a 2-year warranty on MRO Electric. We also offer I/O modules from other manufacturers such as Modicon and ABB.

Field wiring

For the ASBDAU204 configuration, 60/75 copper (Cu) is used for power connections, using 4.5 inch pounds. Torque of the set screw. To prevent equipment operation errors, follow the following guidelines:

Use a shielded twisted pair cable (e.g. Beton 9418).

Only ground the shielding layer of each signal cable on DAU 204. At the other end of each signal cable, strip the shield and insulate it from the signal transmission line.

Route each signal cable as far away as possible from electrical noise sources such as motors, transformers, contactors, and especially AC devices.

Route signal cables in conduits different from AC cables and power cables.

If the signal cable must pass through the AC cable or power cord, make sure they cross at a right Angle.

When connecting field devices to modules, keep the unshielded portion of the signal transmission line as short as possible.

After the terminal, use the attached key to prevent the terminal from being accidentally switched.

advantage

The Modicon AS-BDAU-204 is a 4-channel analog output module designed to control adjustable frequency drivers, positioning valves, dampers, and more. Each channel can be configured independently to provide voltage or current loop output.

In order to function properly, the module requires a power supply from an external power supply (250mA @ 24VDC). When the external power supply is not used, the module takes power from the internal bus and gives an incorrect reading. Do not leave this module unpowered in the rack.

The ASBDAU204 module features open current loop (line break) detection and alerts via leds and accessible registers. ASBDAU204 can be configured to hold the last value if communication with the CPU is lost for more than 1 second, the CPU stops or is powered off.

There is an amber LED on the front of the module that blinks to indicate module failure. The green LED at the top of the front of the module indicates that the module is ready. As data is sent through the channels, the green leds on each channel will remain lit or flash rapidly. in

A red LED on each channel indicates that an open current loop (broken line) or a high loop impedance (>500Ω) has been detected.
