Ethernet switches/infrastructure products launched
A full range of Ethernet switches and infrastructure products includes managed switch co-branded with Cisco, integrating Cisco technology and optimised for EtherNet/IP.
160C Drives are designed to be installed side by side without having to allow for space between the units.
The new 160C incorporates a number of significant improvements including contactor style, feed through, 6 pole power terminals to simplify installation.
Key product features include auto boost, slip compensation, and auto restart/run on power up.

A configured drives service allows engineers to choose a base drive package and then enhance it with numerous options in line with the needs of the application.
Diagnosis and maintenance of machine tools
Rockwell Automation has introduced the QC10 ballbar which gives maintenance technicians a tool for assessing the dynamic motion and positioning precision of machine tools and production machinery.
Integrated automation reduces costs and errors
Getting discrete automation equipment elements to understand, interrogate, integrate and interact with each other is the real challenge in reducing cost, time and errors, says Dave Withenshaw.
There is also line transient protection up to 6kV and a plug-in DeviceNet communication module.
The 160 C is normally supplied for three-phase, 415v operation for applications up to 4.0 kW.
It is also available in 240v single and three phase options.
Two frame sizes cover the complete range.
The units can be panel mounted or will fit onto a standard 35mm DIN rail and are available either as an Analogue Signal Follower or Preset Speed Model.
The Analogue model can be programmed for control via four preset speeds, PI Control or Analogue with one preset speed.
For applications where more than four presets are required, a Preset Speed Model is available.
This is controlled via three digital inputs that provide eight independent preset speeds and two speed dependent accel/decel ramp times.
Also new are the hinged terminal guards that allow easy access and identification of the power terminals and meet IP20 finger protection.
The terminal guards are captive and help to eliminate the potential risk of the guard not being replaced once the wiring is complete.
Start up is simple using one of the four different operator interfaces that are available.
The standard Ready/Fault Panel tells the operator whether the drive is ready for operation or if a fault condition is present.
Alternatively, the unit can be supplied with a Program Keypad Module.
This interface provides the ability to monitor and/or change all drive parameters, as well as providing local keypad control (start, stop and reverse).
This module also reports specific fault codes, input status and drive status information, that can be used in performing diagnostics and troubleshooting.
Optional DeviceNet and RS232 communication modules, provide a low cost solution for controlling and monitoring the drive.
The 160C can also be programmed using the new Allen-Bradley Drive Explorer software.
The communication modules attach directly to the front of the drive (in place of the Program Keypad Module or Ready/Fault Panel) adding less than 25mm to the overall depth, reducing installation time and saving valuable panel space.
The 160 C offers outstanding performance related to acceleration, Torque/Speed and response to load change.
Excellent current regulation allows faster acceleration and in turn allows more duty cycles per hour.
Smooth controlled current and torque, reduce undesirable mechanical vibrations, helping to prolong motor and equipment life.
The Auto-Boost feature (IR Compensation) automatically adjusts output voltage to improve low speed torque performance across the entire speed range.
The Slip Compensation feature helps improve overall speed regulation.
This allows the drive to maintain the desired commanded output frequency as loading increases.
Even with shock loads demanding 150% more torque, the Allen-Bradley Bulletin 160 C maintains tight control of both current and speed.
A significant benefit of speed control is the reduction in energy consumption as the speed of the fan /pump is reduced.
Controlling the speed with the Allen-Bradley Bulletin 160 C offers reduced energy costs and the controlled starting current can save on the electricity supplier maximum demand charges.
In addition to reduced energy costs and better control, variable speed can also improve efficiency and prolong motor life.
Adjustable acceleration and deceleration times provide inherent soft starting and stopping.
This is further enhanced by the drives programmable 'S' curve adjustment.
This means a huge reduction in starting currents and the elimination of excessive starting torque's.
There is a wide range of accessories available for the 160 C including keypad modules, communication modules, filters and enclosures.
The Allen-Bradley Bulletin 160 Series C Smart Speed Controller, complies with international standards and is well suited to the demands of the global marketplace.
Each unit is individually tested and with its unique combination of innovative design, desirable features, compact size and highly attractive price, represents the benchmark in the microdrive market. Request a free brochure from Rockwell Automation ...
