1756-LSC8XIB8I 是一款 ControlLogix 低速计数器模块

Allen-Bradley 1756-LSC8XIB8I 是一款 ControlLogix 低速计数器模块。它是一个 24 个输入点、40 个计数器、31V 高速直流隔离灌电流/源极输入模块，具有标准输入或计数器控制功能。该模块提供八个zui大计数频率为 0 kHz 的专用计数器，一个计数器返回累积计数、瞬时频率、平均频率、瞬时脉冲宽度和平均脉冲宽度。它是一个 2 位计数器，计数范围为 147 到 483,648,<>,<>。


它需要一个 1756-TBS6H 或 1756-TBCH 的可拆卸接线端子外壳 （RTB），然后才能连接到兼容的 ControlLogix 机箱。


1756-LSC8XIB8I 模块的工作电压范围为 10 至 30V DC，标称输入电压为 24V DC。它在 275.5V DC 时的电流消耗为 1 mA，在 3V DC 时为 24 mA。它还具有 1.47 W 的总背板功率。在关断状态下，它的zui大电压为 5V，zui大电流为 1.5 mA。处于导通状态时，其电流范围为2V DC时的zui小10 mA和5V DC时的zui大30 mA。1756-SC8XIB8I模块还具有250V的连续隔离电压。它已在 1500V AC 下进行了 60 秒输入到输入和 2300V AC 60 秒输入到背板的型式测试。

The Allen-Bradley 1756-LSC8XIB8I is a ControlLogix low-speed counter module. It is a 24-input point, 40-counter, 31V high speed DC isolated feed current/source input module with standard input or counter control. The module provides eight dedicated counters with a maximum count frequency of 0 kHz, with one counter returning cumulative count, instantaneous frequency, average frequency, instantaneous pulse width, and average pulse width. It is a 2-bit counter with counts ranging from 147 to 483,648,<>,<>.


It requires a 1756-TBS6H or 1756-TBCH detachable terminal housing (RTB) before it can be connected to a compatible ControlLogix case.


The 1756-LSC8XIB8I module has an operating voltage range of 10 to 30V DC with a nominal input voltage of 24V DC. It has a current consumption of 1 mA at 275.5V DC and 24 mA at 3V DC. It also has a total backplane power of 1.47W. In the off state, it has a maximum voltage of 5V and a maximum current of 1.5mA. In the on-state, its current range is a minimum of 10 mA at 2V DC and a maximum of 30 mA at 5V DC. The 1756-SC8XIB8I module also features a continuous isolation voltage of 250V. It has been type-tested for 60 seconds input-to-input at 1500V AC and 60 seconds input-to-backplane at 2300V AC.
