Allen-Bradley 1756-DHRIOXT 是 ControlLogix Data Highway Plus/远程 I/O 通信模块中的一款环境产品。它支持 Data Highway Plus –DH+ 消息传递、控制和信息协议 – CIP 消息传递以及远程 I/O 通信。1756-DHRIOXT 有助于不同网络上的设备之间的通信，它可以通过多达三个机箱和四个通信网络路由消息。

1756-DHRIOXT 在每个远程 I/O 通道上支持 32 个逻辑机架连接，在每个远程 I/O 通道上支持 16 个块传输连接。它的 DH+ 连接允许每个 DH+ 通道多 32 条 DH+ 消息。DH+ 的通信速率为 57.6 Kbps；RIO 为 57.6 Kbps、115.2 Kbps 和 230.4 Kbps。它在 5.1V DC 时的电流消耗为 850 mA，在 24V DC 时的电流消耗为 1.7 mA。它还支持多 32 个 Logix 连接。

基于机箱的 1756-DHRIOXT 可以插入背板的任何插槽中。它与 1756-A4LXT、1756-A5XT、1756-A7XT、1756-A7LXT ControlLogix 机箱和标准 1756-PBXT 电源兼容。它具有两个端口，可单独选择用于 DH+ 或远程 I/O。它具有基本绝缘类型的 30V（连续）隔离电压。ControlLogix-XT 型号，其工作温度范围为 -25-70 °C (-13-158 °F)。 

Allen-Bradley 1756-DHRIOXT is an environmental product in the ControlLogix Data Highway Plus/ Remote I/O communication module. It supports Data Highway Plus - DH+ messaging, control and information protocol - CIP messaging, and remote I/O communication. The 1756-DHRIOXT facilitates communication between devices on different networks, and it can route messages through up to three chassis and four communication networks.

The 1756-DHRIOXT supports 32 logical rack connections per remote I/O channel and 16 block transport connections per remote I/O channel. Its DH+ connection allows an additional 32 DH+ messages per DH+ channel. DH+ communication rate is 57.6 Kbps; RIO is 57.6 Kbps, 115.2 Kbps, and 230.4 Kbps. It has a current consumption of 850 mA at 5.1V DC and 1.7 mA at 24V DC. It also supports 32 more Logix connections.

The chassis based 1756-DHRIOXT can be inserted into any slot on the backplane. It is compatible with 1756-A4LXT, 1756-A5XT, 1756-A7XT ControlLogix enclosures and standard 1756-PBXT power supplies. It has two ports that can be selected separately for DH+ or remote I/O. It has a basic insulation type of 30V (continuous) isolation voltage. The ControlLogix-XT model has an operating temperature range of -25-70 °C (-13-158 °F).
