1794-IB32 输入接口设备 分布式 I/O 组件

【产品详情】

1794-IB32 是 Allen-Bradley 模块，属于分布式 I/O 组件的 Flex I/O 产品系列。该模块是一种输入接口设备，允许将现场仪表和电气设备（如按钮设备、限位开关、接近传感器、浮子开关、过程开关、继电器触点和接触器辅助触点）集成到任何自动控制系统或过程中。

1794-IB32 最多可容纳三十二 （32） 个直流输入设备。它是一个 32 通道电流灌电流模块，每个通道的最小导通电压范围为 192.VDC，最大范围为 31.2VDC，标称信号电平为 24VDC。

1794-IB32 能够与 Flex I/O 通信适配器（如以太网、ControlNet、远程 I/O 和其他适配器）一起安装。只要遵循 Flex I/O 安装要求，此模块支持的安装实例数量就没有限制。

1794-IB32是一款高密度输入通道。32 个通道中的每一个都配有 LED 指示灯，用于监控每个通道的活动。这有助于更快地识别有源通道并验证正常工作的输入设备。这些 LED 指示灯在接收到信号时仅通电，并在没有信号时关闭。

该模块连接到 Flex I/O 端子底座。端子底座提供输入和电源端子以及DIN导轨安装插槽。与此高密度输入模块一起使用的兼容端子底座为 1794-TB32、1794-TB32S、1794-TB62DS 和 1794-TB62EXD4X15。端子底座还允许在通电的情况下移除和插入模块。

1794-IB32 的标称导通电压为 24 伏直流电，导通电压范围从最低 19.2 伏直流电到最高 31.2 伏直流电。其最大关断状态电压为 5 伏直流电，最大关断状态电流为 1.5 毫安。1794-IB32 的标称导通电流为 4.1 毫安（24 伏直流电），范围从最小 2 毫安到最大 6 毫安。该模块的 FlexBus 电流为 30 毫安（5 伏直流电）。虽然各个通道之间没有隔离，但 1794-IB32 的隔离电压为 50 伏，在系统和现场侧之间是连续的。它在 31.2 伏直流电下的最大散热为 20.47 BTU/小时，在 31.2 伏直流电下的最大功耗为 6 瓦。该模块的工作温度为 0 至 55 摄氏度，而其存储温度为 -40 至 85 摄氏度。它在 10 至 500 赫兹时的工作振动为 5 G，工作冲击为 30 G，非工作冲击为 50 G。1794-IB32 还具有 5% 至 95% 的非冷凝相对湿度范围。

【英文介绍】

The 1794-IB32 is an Allen-Bradley module that belongs to the Flex I/O product family of distributed I/O components. The module is an input interface device that allows the integration of field instrumentation and electrical equipment such as push button devices, limit switches, proximity sensors, float switches, process switches, relay contacts and contactor auxiliary contacts into any automatic control system or process.

The 1794-IB32 accommodates up to thirty-two (32) DC input devices. It is a 32-channel current feed current module with a minimum on-voltage range of 192.VDC per channel, a maximum range of 31.2VDC, and a nominal signal level of 24VDC.

The 1794-IB32 can be installed with Flex I/O communication adapters such as Ethernet, ControlNet, remote I/O, and other adapters. As long as the Flex I/O installation requirements are followed, there is no limit to the number of installed instances supported by this module.

The 1794-IB32 is a high-density input channel. Each of the 32 channels is equipped with an LED indicator to monitor the activity of each channel. This helps identify active channels more quickly and verify properly functioning input devices. These LED indicators are only powered on when a signal is received and turn off when there is no signal.

The module is connected to the Flex I/O terminal base. The terminal base provides input and power terminals and DIN rail mounting slots. Compatible terminal bases for use with this high-density input module are 1794-TB32, 1794-TB32S, 1794-TB62DS, and 1794-TB62EXD4X15. The terminal base also allows the module to be removed and inserted with power on.

The 1794-IB32 has a nominal on-voltage of 24 volts DC, with on-voltage ranges from a minimum of 19.2 volts DC to a maximum of 31.2 volts DC. The maximum turn-off voltage is 5 volts DC and the maximum turn-off current is 1.5 MA. The 1794-IB32 has a nominal conducting current of 4.1 mA (24 volts DC), ranging from a minimum of 2 mA to a maximum of 6 mA. The FlexBus current of the module is 30 MA (5 volts DC). Although there is no isolation between the individual channels, the isolation voltage of the 1794-IB32 is 50 volts, which is continuous between the system and the field side. It has a maximum heat dissipation of 20.47 BTU/ hour at 31.2 volts DC and a maximum power consumption of 6 watts at 31.2 volts DC. The module operates at a temperature of 0 to 55 degrees Celsius, while its storage temperature is -40 to 85 degrees Celsius. It has an operating vibration of 5 G at 10 to 500 Hz, an operating shock of 30 G, and a non-operating shock of 50 G. The 1794-IB32 also has a non-condensing relative humidity range of 5% to 95%.
