SureCross DX85 Modbus RTU Remote I/O Device

0 131629 2

Configurable Modbus slave remote I/O device with four sourcing discrete inputs, four sourcing discrete outputs, two 0 to 20 mA analog
inputs, and two 0 to 20 mA analog outputs

Features

The SureCross™ wireless system is a radio frequency network with integrated I/O that
can operate in most environments while eliminating the need for wiring runs. Systems are
built around a Gateway, which acts as the wireless network master device, and one or
more Nodes. A remote I/O device with a Modbus interface is used to expand the I/O of the
Gateway device or the Modbus host.

• Wireless industrial I/O device with four sourcing discrete inputs, four sourcing discrete
outputs, two 0 to 20 mA analog inputs, and 0 to 20 mA two analog outputs

• 10 to 30V dc power input

• Selectable Modbus slave address

• Modbus RTU protocol using RS-485

• The DX85...C models are certified for use in Class I, Division 2, Group A, B, C, D; and
Zone 2 (Group IIC) Hazardous Locations when properly installed in accordance with
the National Electrical Code, the Canadian Electrical Code, LCIE/ATEX, or applicable
local codes/regulations (see Specifications)

WARNING: Not To Be Used for Personnel Protection
Never use this product as a sensing device for personnel protection. Doing so could lead to seri-

ous injury or death. This product does NOT include the self-checking redundant circuitry necessary to

allow its use in personnel safety applications. A sensor failure or malfunction can cause either an ener­gized or de-energized sensor output condition.

The SureCross DX80 Wireless Network

The SureCross DX80 wireless I/O network provides reliable monitoring without the burden of wiring or conduit installation. The SureCross
wireless network can operate independently or in conjunction with a host system, PLC, and/or PC software.

Each wireless network system consists of one Gateway and one or more Nodes. Devices ship with factory defined inputs and outputs
that may be all discrete, all analog, or a mix of discrete and analog I/O.

The SureCross DX80 network is a deterministic system—the network identifies when the radio signal is lost and drives relevant outputs
to user-defined conditions. Once the radio signal is reacquired, the network returns to normal operation.

SureCross DX80 Gateways and Nodes

A Gateway acts as the master device within each radio network, initiates communication and reporting with the Nodes, and controls the
timing for the entire network.

The Gateway also holds the configuration for the network. Every wireless network must have one Gateway that schedules communica­tion traffic and controls the I/O configuration for the network. A radio network contains only one Gateway, but can contain many Nodes.
Similar to how a gateway device on a wired network acts as a “portal” between networks, the SureCross Gateway acts as the portal
between the wireless network and the central control process.

A Node is a wireless network end-point device used to provide sensing capability in a remote area or factory. The Node collects data
from sensors and communicates the data back to the Gateway. Nodes are available in a wide variety of power or input/output options.
Each Node device can be connected to sensors or output devices and reports I/O status to the Gateway.

DX85 Modbus RTU I/O Slaves

Use the DX85 Modbus RTU I/O devices to expand the I/O of a Modbus master device. DX85s are hardwired to Modbus master devices
using RS-485 and use Modbus RTU to exchange data. DX85s are available with discrete, analog, or a mix of discrete and analog I/O.
