DeviceNet is a digital, mult-drop network that connects and serves as a communication network between industrial controllers and I/O devices. Each device and/or controller is a node on the network. DeviceNet is a producer-consumer network that supports multiple communication hierarchies and message prioritization. DeviceNet systems can be configured to operate in a master-slave or a distributed control architecture using peer-to-peer communication. DeviceNet systems offer a single point of connection for configuration and control by supporting both I/O and explicit messaging. DeviceNet also has the unique feature of having power on the network.

Brad product lines are developed in compliance with the standards and specifications published by industrial organizations to guarantee you a high level of performance, reliability and availability. An active member of the ODVA, Woodhead Industries provides the most complete product offering and technical support for your DeviceNet network - including gateways, diagnostic tools, network interface cards, PLC interface modules, physical media and I/O devices.

The BradConnectivity™ line up of DeviceNet media is the standard by which all other DeviceNet connection media are measured. We pioneered the market for miniature industrially rated sealed connectors presenting the first quick disconnect alternative to hardwiring. Today BradConnectivity products bring this same quality and durability to the same connectors used in DeviceNet networks. Choices and feature-rich products make them reassuring to specify as part of your DeviceNet system. From tees, splitters and passive boxes, diagnostic aids such as the PowerMonitor tees, to the simple-to-use handheld diagnostic NetMeter, BradConnectivity products are your choice for DeviceNet infrastructure products.

Mini-Change connectors:

Phosphur bronze contacts - the best contact material in the industry - provides better yield strength and increased resistance to stress

Quad Beam design assures consistent pressure is maintained over the life of the connector, assuring reliable performance

Wide variety of cable options: Thick, Thick Class I, Mid, Thin-600V and TPE-jacketed Flex Thin cable

E-coated, stainless steel or nickel brass coupling nut option. Anti-vibration feature prevents back-out. Stainless steel optional for food/beverage or outdoor environments

gold over nickel-plated contact material fro highest reliability - exceeds ODVA specifications

Micro-Change connectors:

Phosphur bronze contacts - the best contact material in the industry - provides better yield strength and increased resistance to stress

Overmolded materials designed for industrial environments, provides strain relief

Cable options include: Thin, Thin-600V and Thin TPE-jacketetd Flex

E-coated, stainless steel or nickel brass coupling nut option. Anti-vibration feature prevents back-out. Stainless steel optional for food/beverage or outdoor environments

gold over nickel-plated contact material fro highest reliability - exceeds ODVA specifications

DeviceNet cable consists of a shielded twisted data pair and an independently shielded twisted power pair for the 24V DC bus power. These independently shielded pairs are then encased in an additional outer shield. Connections from the trunk line to the active nodes are generally made via a 5-pole Mini-Change connection using "thick" cable (mid calbe can also be used). Both ends of the trunk line must be terminated with 121 ohm resistors.

BradConnectivity solutions for DeviceNet thick media include:

bulk cable

cordsets

receptacles

bus drop tees

diagnostic tees

surge suppressors

trunk gender changers

distribution boxes

termination resistors

field attachable connectors

Drops are branches off the trunk and generally use "thin" cable up to 6m (20ft) in length. "Mid" cable can also be used for longer drop lengths or to standarize with "mid" turnk cable.

I/O modules with output connections require 24V DC auxiliary power which is fed through the block via a 4-pole Mini-Change connection. For safety reasons, the auxiliary power is brought to the block using a female connector so as to never have "live" power available on exposed pins. In some cases, machine stop circuits are run through the same 4-pole connectors. Machine stop drop or power tees, as well as termination plugs, are generally colored red for fast identification.

BradConnectivity solutions for DeviceNet power media include:

cordsets

auxiliary power and machine stop tees

power taps
