Rockwell Automation has announced a new line of current-limiting, moulded-case circuit-breakers (MCCBs) which, it says, react to circuit overloads two to three times faster than standard breakers. The Allen-Bradley Bulletin 140G breakers protect against overloads, short-circuits and ground-fault conditions.
Siemens has announced a new generation of motor-protection relays designed to protect motors against overheating by measuring the temperatures at points at risk of overheating in a motor using PTC (positive temperature coefficient) thermistors integrated into the windings. The Sirius 3RN2 relays replace the earlier 3RN1 series and, with widths of 17.5 and 22.5mm, need less space in control cabinets.
Yaskawa has released a new range of general-purpose variable-speed drives that can control induction, permanent magnet (PM) or synchronous-reluctance motors without needing any tuning. The GA700 drives, which were previewed at the 2015 SPS IPC Drives Show in Germany, incorporate a “smart power saver” function claimed to boost the efficiency of induction motors by 6% at 20% speed, as well as improving the efficiency of PM motors by up to about 2%. Another function, called MPTA (maximum torque per ampere), minimises the current drawn, according to the load.
Rockwell Automation has announced an industrial security appliance incorporating new security technologies designed to protect plant-floor systems. It says that the Allen-Bradley Stratix 5950 overcomes limitations of most IT firewalls, which cannot protect against threats to industrial network traffic.
Omron in Japan has announced a total of 15,583 controls products, in seven categories, forming a second wave of factory automation control devices built on a common design platform for unified product specifications. The products include many items for use in control panels – such as relays, switch-mode power supplies, pushbutton switches and terminal blocks, and power monitors – as well as a compact machine controller which executes Ladder Diagram (LD) instructions in 3.3ns, said to be the fastest in its class.
GE Automation & Controls has announced a modular control technology that integrates with the industrial Internet to deliver what it claims are new levels of productivity. It says that early adopters of the Industrial Internet Control System (IICS) have reported 7% gains in asset performance and 22% increases in efficiency. It also expects the IICS to cut maintenance costs by around 40%.
California-based Maxim Integrated Products has announced a pocket-sized PLC development platform that, it asserts, will redefine how factories operate, as well as enabling Industry 4.0 applications. In a volume of less than 10in3 (164cm3), the platform provides 30 IOs (including four analogue inputs, one analogue output, eight digital inputs and eight digital outputs), four IO-link ports, three motion controllers, and diagnostics. It incorporates what are claimed to be the industry’s smallest brushed DC motor drivers, as well as incremental encoder inputs.
NSK has announced a pair of laser-based systems for aligning belts and shafts which, it says, are easy to set up, even over long distances. The tools have been developed in response to the fact that more than half of machines run out-of-alignment, causing higher loadings than necessary, and reducing performance.
The Swedish industrial communications specialist HMS Industrial Networks has announced a wireless access point that is designed to be mounted on a machine or cabinet like a bolt to provide wireless access via a WLAN, or Bluetooth or Bluetooth Low Energy. The IP67-protected Anybus Wireless Bolt can be used to configure a machine remotely, to replace cables, or to connect the system to a cloud service.
The Californian controls manufacturer Bedrock Automation has developed an industrial power supply which, it asserts, sets new standards for onboard intelligence, durability and cyber-security. Starting with a blank sheet of paper, Bedrock’s engineers designed the SPS.500 to be “the ultimate power supply”.
Belden has developed a “game-changing” RJ-45 connection system that, it claims, will cut termination times by up to 60%. The REVConnect system uses the same termination core for either a plug or a socket, and is suitable for all Category 5e, Category 6 and Category 6A RJ-45 connections. A single tool performs every step of the termination process, including cable preparation.
The belt-maker Gates claims to have developed the first bandless V-belt that needs no servicing or maintenance. Its new Quad-Power 4 belt does not need to be “run in” or re-tensioned within 48 hours of being installed, resulting in fewer production standstills and lower maintenance costs, especially for difficult-to-reach belt drives.
The industrial communications specialist Belden and the Danish software developer Secomea have joined forces to offer a simple, secure way to provide remote network access, programming and diagnostics. They are offering a combined hardware and software package that will help users to take advantage the increased connection of devices made possible by the Industrial Internet of Things (IIoT).
The robot-maker Yaskawa has unveiled its first collaborative robot to be sold outside of Japan. The Motoman HC10 can handle loads up to 10kg and has a reach of 1.2m.
Mitsubishi Electric has announced a compact, easy-to-install alternative to line-scan cameras for inspecting defects on flat surfaces. Called the line-scan bar, it offers high-quality, distortion-free images up to the edges of materials moving at speeds of up to 1,000m per minute, or even faster.
