Products Description

The Allen-Bradley 1756-DHRIO is a ControlLogix Data Highway Plus/Remote I/O communication interface module. This module has Two (2) channels, supporting communication rates of 57.6 kilobytes per second, 115.2 kilobytes per second, and 230.4 kilobytes per second, depending on the cable length. It can transfer a message through a maximum of three chassis and four communication networks. With this module, information exchange can be done among devices such as PLCs, SLCs, and ControlLogix controllers, even on different networks.

RIO and DH+ protocol uses the same cable type. Recommended cables are Belden 89463 twinaxial, 0.52 mm² (20 AWG) rated at 200 °C (392 °F). Applicable spare connector is Phoenix terminal with part number MVSTBR2.5/3-ST BK AU.

DH+ and Remote I/O network requires the use of a terminating resistor as it follows daisy-chain topology. This resistor is installed at the first and last node of the network. Resistor values depend on the network speed. 82 Ohms is used for network speed of 230.4Kbps. 150 Ohms is used for network speed of 57.6 Kbps or 115.2 Kbps. Other considerations are also considered including the type of devices connected to the network. The terminating resistor is installed across line 1 and line 2 of the cable. The 3rd cable is the shield cable.

To terminate the cable following RIO protocol, Line 1 is connected to the bottom pin or terminal 1, shield cable is terminated to the middle pin and Line 2 is terminated to the last pin. To wire the cable appropriately as DH+ protocol, simply reverse the connection of Line 1 and Line 2.

This module supports communication with Flex IO, POINT IO systems and messaging functions with PLC 5, SLC, CompactLogix and ControlLogix controllers as well.
