1756-LSC8XIB81 低速计数器模块 具有标准输入或计数器控制功能

【产品详情】

Allen-Bradley 1756-LSC8XIB8I是一款ControlLogix低速计数器模块。它是一款 8 个输入点、8 个计数器、24V 高速直流隔离灌电流/拉电流输入模块，具有标准输入或计数器控制功能。该模块提供 8 个最大计数频率为 40 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 31 位计数器，计数范围为 0 到 2,147,483,648。

它需要 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。它还具有 275 mA 的电流消耗（5.1V DC）和 3 mA（24V DC）。它还具有 1.47 W 的总背板功率。在关断状态下，它的最大电压为 5V，最大电流为 1.5 mA。处于导通状态时，其电流范围为 10V DC 时的最小 2 mA 和 30V DC 时的最大 5 mA。1756-SC8XIB8I模块还具有250V的连续隔离电压。它已经在 1500V AC 下进行了 60 秒输入到输入的型式测试，在 2300V AC 下进行了 60 秒输入到背板的型式测试。

该模块的散热为 12.97 BTU/hr。从关到开，反之亦然，其螺钉到背板输入延迟时间为标称值 14 μs/最大值 23 μs + 用户可配置的滤波时间为 0 至 30,000 μs。它的工作温度范围为 0 至 60 摄氏度，非工作温度范围为 -40 至 85 摄氏度。它在 10 至 500 Hz 时的振动为 2 g，工作冲击为 30 g，非工作冲击为 50 g。

【英文介绍】

The Allen-Bradley 1756-LSC8XIB8I is a ControlLogix low-speed counter module. It is an 8 input point, 8 counters, 24V high speed DC isolated feed/pull current input module with standard input or counter control. The module offers eight dedicated counters with a maximum count frequency of 40 kHz, with one counter returning cumulative count, instantaneous frequency, average frequency, instantaneous pulse width, and average pulse width. It is a 31-bit counter with a count range from 0 to 2,147,483,648.

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 also has 275 mA of current consumption (5.1V DC) and 3 mA (24V 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 2 mA at 10V DC and a maximum of 5 mA at 30V DC. The 1756-SC8XIB8I module also features a continuous isolation voltage of 250V. It has been type-tested for 60 seconds input-to-input under 1500V AC and 60 seconds input-to-backplane under 2300V AC.

The module has a heat dissipation of 12.97 BTU/hr. From off to on and vice versa, its screen-to-backplane input delay time is a nominal value of 14 μs/ a maximum of 23 μs + user-configurable filtering time of 0 to 30,000 μs. It has an operating temperature range of 0 to 60 degrees Celsius and a non-operating temperature range of -40 to 85 degrees Celsius. It has a vibration of 2 g at 10 to 500 Hz, a working shock of 30 g, and a non-working shock of 50 g.
