Allen-Bradley 1786-RPA 是一款 ControlNet 模块化中继器适配器。该模块是 ControlNet 通信网络附件,主要用于扩展 ControlNet 网络的长度以及组装不同的拓扑结构,例如星形、环形、线性或点对点拓扑。该中继器模块也可用于将 ControlNet 电缆介质从同轴电缆物理转换为光纤以及光纤到 ControlNet 同轴电缆的物理转换。
ControlNet网络是一种工业通信协议,用于设备的多点通信。这些设备可以是 ControlNet 客户端模块、控制器、可视化系统和网关的混合体。ControlNet 网络由称为 Trunk 的主要通信高速公路组成,其中设备或节点通过 ControlNet 分流器连接。ControlNet 网络支持最远 1000 m 的距离。如果网络超过此最大距离,则可以使用 1786-RPA。
1786-RPA 兼容 1786-RPCD 中继器双铜模块、1786-RPFS 中继器短距离光纤模块、1786-RPFM 中距离光纤模块、1786-RPFRL 光纤环形中继器模块和 1786-RPFRXL 光纤环形中继器模块。串联的最大允许适配器为 20 1786- RPA。
该中继器适配器模块支持直接安装到安装板或使用DIN导轨。与DIN导轨安装相比,直接面板安装具有更高的抗振性和抗冲击性。该模块支持水平或垂直方向,并由 18-36VDC 的外部电压供电。
该中继器适配器模块配有一 (1) 个用于输入电源连接的可拆卸接线端子、一 (1) 个 75 欧姆终端电阻器和两 (2) 个 DIN 导轨锁。
1786-RPAB 中继器适配器需要 24 伏直流输入电源。在 5 VDC 时,它可以提供最大 1.6 A 的背板输出电流。Allen-Bradley 1786-RPAB 中继器适配器具有不同的功能,例如延长网络长度、执行从同轴或铜介质到光纤介质的网络介质转换,以及从光纤介质到同轴或铜介质的相反方式、为中继器模块供电,以及用于创建环形、星形或点对点拓扑。
中继器适配器和中继器模块都配备了 2 个状态指示灯,例如 Ready 和 Fault,分别指示通电故障状态。整个 1786-RPA 中继器适配器的尺寸约为 4 x 4 x 3 英寸或 10 x 10 x 8 厘米,重量约为 7 盎司或 0.20 千克。此 B 系列中继器适配器也称为型号 1786-RPA/B。

Wire size: 0.21... 3.3 mm2 (24...) with a temperature rating of 105 °C (221 °F) or higher and a maximum insulation of 1.2 mm (3/64 in.) 12 AWG) Solid or stranded copper wire, power connection with maximum insulation of 1.2 mm (3/64 in.)
The Allen-Bradley 1786-RPA is a ControlNet modular repeater adapter. This module is a ControlNet communication network accessory designed to extend the length of the ControlNet network and to assemble different topologies, such as star, ring, linear, or point-to-point topologies. The repeater module can also be used to physically convert ControlNet cable media from coaxial cable to optical fiber and from optical fiber to ControlNet coaxial cable.
The ControlNet network is an industrial communication protocol used for multi-point communication of devices. These devices can be a mix of ControlNet client modules, controllers, visualization systems, and gateways. The ControlNet network consists of major communication highways called trunks, where devices or nodes are connected via ControlNet shunt. The ControlNet network supports a distance of up to 1000 m. If the network exceeds this maximum distance, 1786-RPA can be used.
The 1786-RPA is compatible with 1786-RPCD repeater double copper modules, 1786-RPFS repeater Short range fiber modules, 1786-RPFM medium range fiber modules, 1786-RPFRL Fiber ring repeater modules, and 1786-RPFRXL fiber ring repeater modules. The maximum allowable adapter in series is 20 1786-RPA.
The repeater adapter module supports mounting directly to the mounting plate or using DIN rails. Direct panel mounting offers higher vibration and impact resistance compared to DIN rail mounting. The module supports horizontal or vertical orientation and is powered by an external voltage of 18-36VDC.
The repeater adapter module is equipped with one (1) detachable terminal for input power connection, one (1) 75 ohm terminal resistor, and two (2) DIN rail locks.
The 1786-RPAB repeater adapter requires 24 volts DC input power. At 5 VDC, it can provide up to 1.6 A backplane output current. The Allen-Bradley 1786-RPAB repeater adapter has different functions, such as extending network length, performing network media conversion from coaxial or copper media to fiber media, and vice versa from fiber media to coaxial or copper media, powering repeater modules, and for creating ring, star, or point-to-point topos.
Both the repeater adapter and the repeater module are equipped with 2 status indicators, such as Ready and Fault, indicating the power-on failure status, respectively. The entire 1786-RPA repeater adapter measures approximately 4 x 4 x 3 inches or 10 x 10 x 8 cm and weighs approximately 7 ounces or 0.20 kg. This Series B repeater adapter is also known as Model 1786-RPA/B.
