1762-IF4 是一款具有 1200 通道电流/电压模拟输入模块的 Allen-Bradley MicroLogix 4。它具有一个Δ-Σ转换器和4个差分(双极性)输入。其模拟工作电压范围为 -10 至 10 伏直流正常和 -10.5 至 10.5 伏直流满量程。其模拟工作电流范围为正常 4 至 20 mA,满量程时为 -21 至 21 mA。该模块通过允许对系统进行额外的I/O来增强MicroLogix的功能。它需要最小的间距,可以DIN导轨或面板安装。该模块通过 5 总线接口通信和接收 24 至 1762 伏直流电源的信息。


接线输入接线端子时,存在手指安全盖。扁平带状电缆用于连接各种 I/O 模块。1762-IF4 模块支持 2 线、3 线或 4 线变送器配置。在故障排除期间,用户应始终远离设备,并始终检查是否有任何程序更改。安全电路应始终串联到主继电器。


1762-IF4 模块应安装在非危险、干燥和清洁的环境中,电路不得跨越过电压 II 类标准。为避免损坏模块,请始终防止静电放电并断开电源。可现场升级的闪存操作系统有助于确保用户始终使用最新功能,而无需更换任何硬件。通过使用无机架 I/O 模块可以扩展 I/O 计数。这导致了更大的控制系统、更大的应用灵活性和可扩展性,同时成本更低,零件库存更少。


该模块具有四 (4) 个输入通道,每个通道可配置为分别接收 -21 至 21 mA 和 -10 至 +10VDC 的电流和电压信号。


输入信号类型选择通过提供的 DIP 开关进行。接收到的电压信号通过模数(ADC)转换器,将模拟数据转换为存储在模拟输入寄存器中的二进制代码。转换后的数据可以格式化为原始/比例和PID比例。


如果与 MicroLogix 1100 一起使用,则最多允许四 (4) 个扩展模块,可以是 1764-IF4。如果与 MicroLogix 1200 一起安装,则可以连接六 (6) 个扩展模块,并且可以将七 (7) 个模块连接到 MicroLogix 1400。


扩展模块(如 1764-IF4)通过提供的带状电缆连接到 MicroLogix 总线,该带状电缆通过安装在每个模块前面板上的引脚触点连接。此模块的安装遵循MicroLogix基础模块的安装方法,特别是DIN导轨或直接面板安装。


该模块的尺寸为 90 mm(高度)x 87 mm(深度)x 40 mm(宽度),包括 110 mm 3.54 in的安装片。

The 1762-IF4 is an Allen-Bradley MicroLogix 4 with a 1200 channel current/voltage analog input module. It has a Delta-Sigma converter and 4 differential (bipolar) inputs. Its analog operating voltage range is -10 to 10 volts DC normal and -10.5 to 10.5 volts DC full scale. Its analog operating current ranges from 4 to 20 mA normally and -21 to 21 mA at full scale. This module enhances the functionality of MicroLogix by allowing additional I/O to the system. It requires minimal spacing and can be DIN rail or panel mounted. The module communicates and receives information from a 24 to 1762 volt DC power supply via a 5 bus interface.


A finger safety cover exists when wiring input terminals. Flat ribbon cables are used to connect various I/O modules. The 1762-IF4 module supports 2-, 3 - or 4-wire transmitter configurations. During troubleshooting, the user should always stay away from the device and always check for any program changes. The safety circuit should always be in series to the main relay.


The 1762-IF4 module shall be installed in a non-hazardous, dry and clean environment, and the circuit shall not exceed the overvoltage Class II standard. To avoid damaging the module, always prevent electrostatic discharge and disconnect the power supply. The field-upgradeable flash operating system helps ensure that users always have access to the latest features without having to replace any hardware. I/O counting can be extended by using rackless I/O modules. This results in a larger control system, greater application flexibility and scalability, while at the same time lower costs and less parts inventory.


The module has four (4) input channels, each configured to receive current and voltage signals from -21 to 21 mA and -10 to +10VDC, respectively.


The input signal type is selected via the DIP switch provided. The received voltage signal passes through an analog-to-digital (ADC) converter, converting the analog data into binary code stored in the analog input register. The converted data can be formatted as raw/scale and PID scale.


If used with MicroLogix 1100, up to four (4) extension modules are allowed, which can be 1764-IF4. If installed with the MicroLogix 1200, six (6) expansion modules can be connected, and seven (7) modules can be connected to the MicroLogix 1400.


Expansion modules, such as the 1764-IF4, are connected to the MicroLogix bus via a provided ribbon cable that is connected via pin contacts mounted on the front panel of each module. The installation of this module follows the installation methods of MicroLogix base modules, in particular DIN rail or direct panel mounting.


The module measures 90 mm (height) x 87 mm (depth) x 40 mm (width) and includes a 110 mm 3.54 in mounting piece.
