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).
