Allen-Bradley 1756-IB16D 直流数字 I/O 模块

【产品详情】

Allen-Bradley 1756-IB16D 是一款 ControlLogix 直流数字 I/O 模块。16 个诊断输入，一组 4 个点，可用于此特定输入模块。它与 1756 ControlLogix 机箱兼容，需要一个 RTB 或可拆卸接线端子外壳，该外壳只能是 1756-TBNH 或 1756-TBSH。

与其他诊断模块一样，1756-IB16D 旨在为控制器提供附加信息，例如空载检测、模块故障发生或清除的时间戳以及脉冲测试。请注意，此模块不指示其电线断开诊断功能的保险丝熔断或移除。

1756-IB16D 的工作电压范围为 10 至 30V DC，电压类别为 12/24V DC 灌电流，标称输入电压为 24V DC。它的输入延迟时间标称值为340μs，硬件延迟时间最高为1 ms，外加用户可选择的“关”至“开”状态滤波时间（0、1或2 ms）。从“开”到“关”的输入延迟时间标称值为 740 μs，硬件延迟时间最高为 4 ms，外加用户可选择的 0、1、9 或 18 ms 滤波时间。它的总背板功率为 0.84W，60 摄氏度时的最大功耗为 5.8W，最大散热为 19.78 BTU/小时。在关断状态下，1756-IB16D 的最大电压为 5W，最大电流为 1.5 mA。处于导通状态时，电流范围为 10V DC 时的 2 mA 至 30V DC 时的 13 mA。此外，其最大浪涌电流为 250 mA。

【英文介绍】

The Allen-Bradley 1756-IB16D is a ControlLogix DC digital I/O module. Sixteen diagnostic inputs, a set of four points, are available for this particular input module. It is compatible with the 1756 ControlLogix case and requires an RTB or detachable terminal housing, which can only be 1756-TBNH or 1756-TBSH.

Like other diagnostic modules, the 1756-IB16D is designed to provide additional information to the controller, such as no-load detection, timestamp of module failure occurrence or clearance, and pulse testing. Please note that this module does not indicate a blown or removed fuse for its wire disconnect diagnostic function.

The 1756-IB16D operates in a voltage range of 10 to 30V DC, with a voltage class of 12/24V DC perfusion current and a nominal input voltage of 24V DC. It has a nominal input latency of 340μs and a hardware latency of up to 1 ms, plus a user-selectable "off" to "on" state filtering time (0, 1 or 2 ms). The input delay time from "On" to "off" is nominal at 740 μs, and the hardware delay time is up to 4 ms, plus a user-selectable filter time of 0, 1, 9 or 18 ms. It has a total backplane power of 0.84W, a maximum power consumption of 5.8W at 60 degrees Celsius, and a maximum heat dissipation of 19.78 BTU/ hour. In the off state, the 1756-IB16D has a maximum voltage of 5W and a maximum current of 1.5mA. When on, the current ranges from 2 mA at 10V DC to 13 mA at 30V DC. In addition, its maximum surge current is 250 mA.
