1746-IB32 是一款 SLC 500 离散输入模块

Allen-Bradley 1746-IB32 是一款 SLC 500 离散输入模块。该模块在 24VDC 的标称电压和 15-30V DC @ 50 °C （122 °F） 或 15-26.4V DC @ 60 °C （140 °F） 的电压范围内工作。该模块通常用于连接电气设备，如开关、传感器、辅助触点和其他二进制或开/关设备。多达三十二 （32） 个输入信号可通过嵌入式 32 个输入模块通道连接到该模块。

它与任何 SLC 500 处理器兼容，理想情况下与 SLC 500 模块化样式硬件兼容。它支持沿控制器本地安装、扩展 I/O 机架或沿 SLC 500 通信适配器安装到远程 I/O 机箱。它直接安装到 1746 机箱的任何可用插槽，但为 SLC 1 控制器保留的插槽 500 除外。

1746-IB32 在 50VDC 时的背板电流消耗为 5 mA，zui 大关断状态输入电压为 5VDC，标称输入电流为 5.1 mA @ 24V DC，zui 大关断状态输入电流为 1.5 mA，对于 ON 到 OFF 和 OFF 到 ON 信号转换，典型信号延迟为 8 ms。

安装模块时，请确保已从机箱中断开电源，因为此模块不支持卸下和带电插入 （RIUP）。它配有一个可拆卸的接线端子，允许远程连接到模块，并简化了维护，因为RTB允许插入另一个相同类型的模块。

1746-IB32 可在背板和 I/O 之间以 1500 伏交流电测试，隔离 60 秒，并具有 1500 伏交流电介质耐受性。在ON状态下，其电路上的zui 小电压为15.0伏直流电，在关闭状态下，其zui 大压降为5.0伏直流，zui 大漏电流为1.5 mA。1746-IB32 模块在 ON 和 OFF 模式下输入端的zui 大信号延迟时间为 3ms，在 5 V DC 标称电压下的总标称输入电流为 1.24 mA。1746-IB32 的工作温度范围在 0 至 60 摄氏度（32 至 140 摄氏度）之间，非冷凝湿度为 5% 至 95%，在 1 至 5 赫兹时具有 200G 的工作振动耐受性和 30G 的冲击等级。

The Allen-Bradley 1746-IB32 is an SLC 500 discrete input module. The module operates in a nominal voltage of 24VDC and a voltage range of 15-30V DC @ 50 °C (122 °F) or 15-26.4V DC @ 60 °C (140 °F). The module is commonly used to connect electrical devices such as switches, sensors, auxiliary contacts, and other binary or on/off devices. Up to thirty-two (32) input signals can be connected to the module via embedded 32 input module channels.

It is compatible with any SLC 500 processor and ideally with SLC 500 modular style hardware. It supports local installation along the controller, extension I/O rack, or installation along the SLC 500 communication adapter to the remote I/O chassis. It is installed directly into any available slot in the 1746 chassis, with the exception of slot 500 reserved for the SLC 1 controller.

1746-IB32 backplane current consumption at 50VDC is 5 mA, maximum turn-off state input voltage is 5VDC, nominal input current is 5.1 Ma@24V DC, maximum turn-off state input current is 1.5 mA, For ON to OFF and OFF to ON signal conversions, the typical signal delay is 8 ms.

When installing the module, ensure that the power is disconnected from the chassis, as this module does not support Remove and Insert Live (RIUP). It comes with a detachable terminal that allows remote connection to the module and simplifies maintenance, as RTB allows the insertion of another module of the same type.

The 1746-IB32 can be tested at 1500 volts AC between the backplane and I/O, isolated for 60 seconds, and has 1500 volts AC dielectric resistance. In the ON state, the minimum voltage on its circuit is 15.0 volts DC, in the off state, its maximum voltage drop is 5.0 volts DC, and the maximum leakage current is 1.5 mA. The 1746-IB32 module has a maximum signal delay time of 3ms at the input in ON and OFF mode and a total nominal input current of 1.24mA at a nominal voltage of 5 V DC. The 1746-IB32 operates in a temperature range of 0 to 60 degrees Celsius (32 to 140 degrees Celsius), non-condensing humidity of 5 to 95 percent, operating vibration tolerance of 200G at 1 to 5 Hertz and a shock rating of 30G.
