1756-OW16I 1756-OX8I输出模块 1756-RIO通信模块

In stock

1756-OX8I是Allen-Bradley的产品，用于ControlLogix平台。该模块是一个继电器输出模块，由八(8)个常开(N.O)和八(8)个常闭(N.C)独立隔离触点组成。
由于这是一个触点输出模块，每个触点可以单独连接10 – 240 VAC范围的交流电压或5-125 VDC范围的DC电压。这使得该模块能够为在不同电压类别下运行的输出设备供电。接触器、电机启动器、变频驱动器、指示灯、信号器面板、发声装置、电机和设备等输出设备是可能连接到该模块的一些负载。

该模块的输出通道是单独隔离的，但也可以作为非隔离继电器输出模块进行接线。这可以通过使用1756-JMPR或第三方跨接线短接可拆卸接线板(RTB)的L1连接来实现。

用于继电器输出模块的兼容RTB是1756-TBCH和1756-TBS6H。这些模块单独购买。通过使用rtb，输出端接被模块化，模块安装、故障排除和更换被简化。RTB防止重新布线或输出信号终止。

此外，对于电阻负载，每个触点输出的预期触点寿命为300 kHz，对于电感负载，预期触点寿命为100 kHz。它的开关频率为1次操作/3 s(额定负载时为0.3 Hz)，平均反弹时间为1.2 ms。

The 1756-OX8I is an Allen-Bradley product for the ControlLogix platform. This module is a relay output module consisting of eight (8) normally open (N.O) and eight (8) normally closed (N.C) independently isolated contacts.

Since this is a contact output module, each contact can be individually connected to an AC voltage in the range of 10 – 240 VAC or a DC voltage in the range of 5 – 125 VDC. This allows the module to power output devices operating in different voltage categories. Output devices such as contactors, motor starters, variable frequency drives, indicator lights, signaler panels, audible devices, motors and equipment are some of the loads that may be connected to this module.

The module’s output channels are individually isolated, but can also be wired as non-isolated relay output modules. This can be accomplished by using the 1756-JMPR or a third party jumper shorting the L1 connection of a removable terminal block (RTB).

Compatible RTBs for use with relay output modules are the 1756-TBCH and 1756-TBS6H. these modules are purchased separately. By using the rtb, output termination is modularized and module installation, troubleshooting, and replacement are simplified. the rtb prevents rewiring or termination of output signals.

In addition, the expected contact life per contact output is 300 kHz for resistive loads and 100 kHz for inductive loads. it has a switching frequency of 1 operation/3 s (0.3 Hz at rated load) and an average bounce time of 1.2 ms. the rtb is also available as a stand-alone module.
