1756-IB16I  分立式输入模块 用于连接分立器件

【产品详情】

Allen-Bradley 1756-IB16I 是一款 ControlLogix 分立式输入模块。该模块具有十六 （16） 个独立隔离的输入通道，可接受输入信号电压范围为 10-30VDC，标称值为 24VDC。该模块通常用于连接分立器件，如按钮、开关、辅助触点和其他提供二进制或 ON-OFF 信号状态的设备。

1756-IB16 是一个单插槽模块，可安装到任何 1756 ControlLogix 机箱上。它可以连接到任何可用的插槽，但专用于 ControlLogix 处理器或通信适配器的 lect most 插槽除外。因此，1756-IB16I 可用于本地 I/O 配置以及远程或分布式 I/O 架构。

1756-IB16I 输入通道具有固有的信号转换延迟。对于OFF到ON的转换，信号延迟为最大1 ms+滤波时间硬件延迟，其中用户可配置的滤波时间，如0 ms、1 ms或2 ms。对于ON到OFF的转换，信号延迟由最大4 ms+滤波时间组成，其中可选滤波时间为0 ms、1 ms、2 ms、9 ms或18 ms。该模块的电流消耗为 100 mA @ 5.1VDC 和 3 mA @ 24VDC，总背板功率要求为 0.58 瓦。

该模块需要使用可拆卸接线端子 （RTB）。RTB 用作模块的端点，可以断开并重新连接到支持相同 RTB 的任何模块。这样，模块更换或迁移就得到了简化，因为不需要移除现有连接。1756-IB16I 的 RTB 是 1756-TBCH 和 1756-TBS6H。

1756-IB16I 的电压类别为 12/24V DC 灌电流/拉电流，工作电压范围为 10 至 30V DC。该模块的标称输入电压为 24V DC，60 摄氏度时的最大功耗为 5 W，散热为 17.05 BTU/小时。在5.1V时，其电流消耗为100 mA，在24V时为3 mA。它还具有 250 mA 峰值的最大浪涌电流（在 22 ms 内衰减至 <37%，无需激活）。在关断状态下，最大电流为1.5 mA，最大电压为5V。该模块在导通状态下的电流范围为 2 mA（10V DC）至 10 mA（30V DC）。该模块在 5.1V 时的电流消耗为 100 mA，在 24V 时为 3 mA。该模块的输入延迟时间取决于其状态（关闭到打开或关闭到打开）。从“关”到“开”，其延迟时间是最多 1 ms 的硬件延迟加上用户可选择的 0 ms、1 ms 或 2 ms 滤波时间。另一方面，从“开”到“关”，延迟时间是高达4 ms的硬件延迟加上用户可选择的0 ms、1 ms、2 ms、9 ms或18 ms的滤波时间。

【英文介绍】

The Allen-Bradley 1756-IB16I is a ControlLogix discrete input module. The module has sixteen (16) independently isolated input channels that accept input signal voltages ranging from 10-30VDC with a nominal value of 24VDC. The module is commonly used to connect discrete devices such as buttons, switches, auxiliary contacts, and other devices that provide binary or ON-OFF signal states.

The 1756-IB16 is a single slot module that can be installed into any 1756 ControlLogix chassis. It can be connected to any available slot, with the exception of the lect most slot dedicated to the ControlLogix processor or communication adapter. As a result, the 1756-IB16I can be used for local I/O configurations as well as remote or distributed I/O architectures.

The 1756-IB16I input channel has an inherent signal conversion delay. For the OFF to ON conversion, the signal delay is a maximum 1 ms+ filter time hardware delay, where the filter time can be configured by the user, such as 0 ms, 1 ms, or 2 ms. For ON-to-off conversion, the signal delay consists of a maximum of 4 ms+ filtering time, with optional filtering times of 0 ms, 1 ms, 2 ms, 9 ms, or 18 ms. The module's current consumption is 100 mA@ 5.1VDC and 3 mA@ 24VDC, with a total backplane power requirement of 0.58 watts.

The module requires detachable terminal (RTB). An RTB acts as an endpoint for a module and can be disconnected and reconnected to any module that supports the same RTB. This simplifies module replacement or migration because there is no need to remove existing connections. The 1756-IB16I's RTBS are 1756-TBCH and 1756-TBS6H.

The 1756-IB16I has a voltage class of 12/24V DC feed/pull current and an operating voltage range of 10 to 30V DC. The module has a nominal input voltage of 24V DC, a maximum power consumption of 5 W at 60 degrees Celsius, and a heat dissipation of 17.05 BTU/ hour. Its current consumption is 100 mA at 5.1V and 3 mA at 24V. It also has a maximum surge current of 250 mA peak (decaying to <37% in 22 ms without activation). In the off state, the maximum current is 1.5mA and the maximum voltage is 5V. The module has a current range of 2 mA (10V DC) to 10 mA (30V DC) in the on-state. The current consumption of the module is 100 mA at 5.1V and 3 mA at 24V. The input delay time of the module depends on its state (off to on or off to on). From "Off" to "on", the delay time is a maximum of 1 ms hardware delay plus a user selectable 0 ms, 1 ms or 2 ms filter time. On the other hand, from "on" to "off", the delay time is up to 4 ms of hardware delay plus the user's choice of 0 ms, 1 ms, 2 ms, 9 ms or 18 ms of filtering time.
