DX85 Modbus RTU Remote I/O

The DX85 Modbus RTU remote I/O devices have a Modbus interface and are used to expand the I/O of a Gateway or Modbus host within the wireless I/O sensor network.

Refer to the 3D Models page to download AutoCAD, STEP, IGES, and PDF models. There are many possible installation configurations for your wireless network. Refer to the System Layouts webpage for a few examples or download the System Layouts document for more detailed examples of some wireless networks.

The standard IP67 base with internal terminal blocks. The low-profile IP20 base with external terminal blocks.

Features

The features of these devices include: 

  • 10 to 30 V dc power input
  • Selectable slave address
  • Modbus RTU protocol using RS-485

Models ending in C use external terminal blocks instead of internal terminal blocks. These "C" models are Class I, Division 2 certified when installed in a suitable enclosure. Certifications are listed on the Classified Areas page.
