Profibus is a standardized global open network communication system with one of the largest installed bases - well over 2 million to date - in factory automation. It allows all automation devices, sensors, actuators, PLCs, etc to communicate with each other over a single bus. Profibus was developed for high-speed communication and fast cyclic updates up to 12Mbits per second.

Woodhead Industries is an active member of PROFIBUS International. For more information on PROFIBUS, go to www.us.profibus.com or www.profibus.com.

Brad solutions for PROFIBUS include cordsets, receptacles, field attachable connectors, I/O modules, PC & PLC interfaces, gateways, diagnostic tools and simulation software. Applications include supervisory HMI messaging, real-time control, bridging networks & devices, physical connections in harsh environments and I/O communications.

Send me more information on BradConnectivity products

BradConnectivity™ products offer the benefits of quick-connect - fast machine commissioning, the elimination of wiring errors, and simple, device additions and replacements - to Profibus networks.

Mini-Change connectors are used to provide the quick-disconnect feature to the auxiliary power for active I/O modules.

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

Gold over nickel plating for highest reliability

E-coated coupling nut for resistance to weld slag. Anti-vibration feature prevents back-out. Stainless steel optional for food/beverage or outdoor environments

Reverse key Micro-Change connectors are used to connect the data line from one device to another. Input and output connections connect into the blocks via reliable Micro-Change family of products.

Gold over nickel plating for highest reliability

Over-molded materials designed for industrial environments and provide stress relief

Nickel-plated brass coupling and shell assembly provides grounding for a fully shielded head design. Anti-vibration feature prevents back-out

Profibus standard 9-pin D-Sub connectors are pre-connected and tested to eliminate wiring errors caused by traditional hard wiring.

D-Sub connector with termination switch and built-in diagnostics provides flexibility in the field

Whether it's active I/O modules or simple terminators, Brad products offer a complete package to make Profibus truly a "plug and play" network.

The main Profibus cable is of a shielded twisted pair design. It does not contain any conductors to power the Profibus modules or nodes, this is provided through the power media. The connectivity for the active modules uses a sheilded BradConnectivity reverse keyway, 5-pole connector design. The data connectivity is complemented with T-Splitters to connect the bus to the active modules and 9-pin D-sub connectivity with other Profibus compatible devices.

Power is supplied to the active modules via a 5 pole Mini-Change connector. Two of the contacts are used to provide power to the module's electronic circuits and any input devices such as proximity switches. A separate and isolated power circuit is provided via another two contacts. This is used for output devices only and is not required on input only modules. This second supply should be controlled via the machine's safety systems to ensure that no outputs are activated during operator interface with the machine.
