1756-OC8 直流输出模块 仅侦听输出数据

【产品详情】

Allen-Bradley 1756-OC8 模块是 ControlLogix 直流输出模块，具有 8 个可用点，一组中有 4 个点。这是一个尚未熔断的模块，因此建议使用熔断的IFM来保护输出。1756-OC8 模块的推荐保险丝是 SOC p/n MQ2-4A 提供的 5x20mm 4A 快速熔断保险丝。请注意，在将模块安装到机箱中的任何可用插槽中之前，必须先安装机箱和电源并接地。此外，将模块安装到机箱时，必须将可拆卸接线端子外壳 （RTB） 连接到模块。对于 1756-OC8 模块，兼容的 20 引脚 RTB 是 1756-TBNH 和 1756-TBSH。

它是一款 48V 直流电源模块，具有 30 至 60V 直流工作电压范围。它的导频电流为 2 A，最小负载电流为 2 mA。该模块在 5.1V 时的电流消耗为 165 mA，在 24V 时为 2 mA，背板总功率为 0.89 W。其浪涌电流为 4 A，每点 10 ms，在 60 摄氏度下每秒可重复一次。在 60 摄氏度时，每个模块的最大电流为 8 A，而在 60 摄氏度时，每个点的最大电流为 2 A。该器件每点的最大关断状态泄漏电流为1 mA，2 A时的最大导通状态压降为2V DC。

该模块从关到开的最大输出延迟时间为 1 ms，从开到关的最大输出延迟时间为 2 ms。它的散热为 16.71 BTU/hr，在 4.9 摄氏度时的最大功耗为 60W。

1756-OC8 模块提供以下通信格式：机架优化、计划输出数据、输出数据、仅侦听机架优化和仅侦听输出数据。您还可以使用此模块选择每个点的故障或程序模式下的状态。可用的选项包括“打开”、“关闭”和“保持最后状态”，其中“关闭”为默认状态。

【英文介绍】

The Allen-Bradley 1756-OC8 module is a ControlLogix DC output module with 8 available points, 4 points in a set. This is a module that has not been blown, so it is recommended to use a blown IFM to protect the output. The recommended fuse for the 1756-OC8 module is the 5x20mm 4A fast fuse provided by the SOC p/n MQ2-4A. Note that the case and power supply must be installed and grounded before installing the module into any available slots in the case. In addition, when installing the module into the chassis, the removable terminal housing (RTB) must be connected to the module. For the 1756-OC8 module, the compatible 20-pin RTBS are 1756-TBNH and 1756-TBSH.

It is a 48V DC power module with a 30 to 60V DC operating voltage range. It has A pilot current of 2 A and a minimum load current of 2 mA. The module's current consumption is 165 mA at 5.1V and 2 mA at 24V, with a total backplane power of 0.89 W. Its surge current is 4 A, 10 ms per point, and can be repeated once per second at 60 degrees Celsius. At 60 degrees Celsius, the maximum current per module is 8 A, while at 60 degrees Celsius, the maximum current per point is 2 A. The device has A maximum turn-off leakage current of 1 mA per point and a maximum on-state voltage drop of 2V DC at 2 A.

The module has a maximum output delay time of 1 ms from off to on and a maximum output delay time of 2 ms from on to off. It has a heat dissipation of 16.71 BTU/hr and a maximum power consumption of 60W at 4.9 degrees Celsius.

The 1756-OC8 module provides the following communication formats: rack optimization, Scheduled output data, Output data, Listen only to rack optimization, and listen only to output data. You can also use this module to select the state in fault or program mode for each point. Available options include "On," "Off," and "Keep Last," where "Off" is the default.
