IC670MDL240是来自现场控制 I/O 模块的十六 （16） 通道离散输入模块。该模块用于连接具有两 （2） 种状态或二进制操作的信号设备，例如按钮设备、限位开关、辅助触点、接近传感器和其他类似操作的设备。该模块作为扩展模块运行，沿总线接口单元 （BIU） 安装，最大消耗 77 mA 电流。

IC670MDL240输入通道在 120-0 VAC 的输入范围内接受 132 VAC 的标称信号电压，沿 15-47 Hz 的输入频率每点输入电流为 63 mA。该模块的典型输入阻抗为 8.6 KOhms，导通状态电压为 70 VAC 至 120 VAC，关断状态电压为 0-20 VAC;导通状态电流为 5-15 mA，关断状态电流为 0 mA 至 2.5 mA。模块的开启响应时间为 12ms，典型值最长为 20 ms，而关闭响应时间典型值为 25 ms，最大响应时间为 40 ms。必须为模块提供外部 120 VAC 电源电压，为连接到IC670MDL240分立输入模块的输入设备供电。

IC670MDL240配有单独的 LED 状态指示灯，用于描述输入通道的逻辑 0 和逻辑 1 状态。在逻辑 0 时，输入点接收关断状态电平的电压和电流，而在逻辑 1 时，输入通道主动接收导通状态电平的电压和电流，从而导致 LED 指示灯被激活。此外，还提供专用的PWR LED指示灯，用于描述从背板接收的功率。

GE Fanuc的现场控制IC670MDL240模块是一个具有16个分组输入点的输入模块。它以 120 伏交流电运行，并从主机系统的 BIU 接收电源，但输入设备需要从额定电压为 120 伏交流电的外部电源获取电源。IC670MDL240模块的顶部有 LED，这些 LED 位于透明材料的窗格下方。有一个PWR LED指示背板电源，每个输入都有单独的LED，用于显示输入是打开还是关闭。为GE现场控制IC670MDL240输入模块供电的BIU或总线接口单元也为其处理智能处理任务。

智能处理职责包括配置故障报告和输入默认设置，并向主机处理器和/或本地处理器提供模块的 16 位或 2 字节离散输入数据。IC670MDL240输入模块从电容和电阻网络产生的输入阈值接收输入滤波。该输入模块的输入电压范围为 0 至 132 伏交流电，频率为 47 至 63 赫兹。各个输入点之间没有隔离，但输入与逻辑以及输入和帧接地之间的隔离为 250 伏交流连续和 1500 伏交流电 1 分钟。

【英文介绍】

The IC670MDL240 is a 16-point discrete input module for the GE Fanuc field control family. The module has sixteen (16) input channels that accept input signal voltages of 63 VAC in the signal range of 120-0 VAC, 132-47 Hz, and user input currents of 15 mA per point. The module consumes 77mA of current from the Bus Interface Unit (BIU) power supply.

The IC670MDL240 is a sixteen (16) channel discrete input module from the field control I/O module. The module is used to connect signal devices with two (2) states or binary operations, such as push button devices, limit switches, auxiliary contacts, proximity sensors, and other devices with similar operations. The module operates as an expansion module, installed along the Bus Interface Unit (BIU) and consumes a maximum of 77 mA of current.

The IC670MDL240 input channel accepts a nominal signal voltage of 132 VAC in the input range of 120-0 VAC, with an input current of 63 mA per point along the input frequency of 15-47 Hz. The module has a typical input impedance of 8.6 KOhms with on-state voltages of 70 VAC to 120 VAC and off state voltages of 0-20 VAC. The on-state current is 5-15 mA, and the off state current is 0 mA to 2.5 mA. The module has an on response time of 12ms with a typical maximum of 20 ms, while the off response time is a typical value of 25 ms with a maximum of 40 ms. The module must be supplied with an external 120 VAC power supply voltage to power the input devices connected to the IC670MDL240 discrete input module.

The IC670MDL240 is equipped with separate LED status indicators that describe the logical 0 and logical 1 states of the input channels. At logic 0, the input point receives the voltage and current at the off status level, while at logic 1, the input channel actively receives the voltage and current at the on-status level, resulting in the LED indicator being activated. In addition, a dedicated PWR LED indicator is provided to describe the power received from the backplane.

GE Fanuc's field control IC670MDL240 module is an input module with 16 packet input points. It runs on 120 volts AC and receives power from the BIU of the host system, but the input device needs to get power from an external power supply rated at 120 volts AC. The IC670MDL240 module has leds at the top, which are located below the panes of transparent material. There is a PWR LED indicating the backplane power supply and a separate LED for each input to show if the input is on or off. The BIU or bus interface unit that powers the GE field control IC670MDL240 input module also handles intelligent processing tasks for it.

Intelligent processing responsibilities include configuring fault reporting and entering default Settings, and providing 16-bit or 2-byte discrete input data for the module to the host processor and/or the local processor. The IC670MDL240 input module receives input filtering from the input thresholds generated by the capacitor and resistance network. The input module has an input voltage range of 0 to 132 volts AC and a frequency of 47 to 63 Hertz. There is no isolation between the individual input points, but the isolation between the input and the logic and between the input and the frame ground is 250 volts AC continuously and 1500 volts AC for 1 minute.
