New proportional valve module
a compact and high-performance solution, allowing hydraulic or pneumatic valves to be connected to the WAGO-I/O-SYSTEM 750. Two single-coil valves or one dual-coil valve can be controlled either uni- or bi-directionally. For each channel or coil, the output current is 2A in 1-channel operation and 1.6A in 2-channel operation. In connection with a lower setpoint/actual value deviation, both small and larger valves can be controlled reliably and with high repeatability. There are two current-controlled PWM1 outputs (24V) with adjustable dither. Discrete dither frequency setting minimises the motion, which is adjusted to the valve around the rest position. This allows the set point to be defined without considering static friction, whilst preventing the valve from being stuck due to medium residues. Set point definition can be adjusted to the application via both scaling and configurable up/down ramps.

Expanded PowerFlex 520-Series of Compact AC Drives debuts PowerFlex 523 AC Drive to meet Machine-Builder needs for “Just Enough” control
I
nspired by global drive-user input, Rockwell Automation engineers designed the Allen-
Bradley PowerFlex 520-Series of compact AC drives,
including the new, economical
PowerFlex 523 AC drive, with flexible features that help users be more competitive. Ideal for builders of simple, stand-alone machines,
the
PowerFlex 523 AC drive balances user needs for “just enough” control with a design that lowers the Total Cost to Design, Develop and Deliver machines.
“When we designed the PowerFlex 520-Series
drives, we traveled to hundreds of drive users around the world to learn firsthand which features they value most today and would want five years from now,” said Jimmy Koh, global marketing manager,
Rockwell
“Stand-alone machine builders wanted ‘just enough’ motor control and emphatically shared the need for features that ease configuration and speed installation. This is where their profitability was most affected, and we designed the
urrently the slimmest modular design available at only 11.5mm module width, Weidmüller’s new “u-remote” modularly designed remote I/O system is distinguished by a plug-in connection level, high component density – as well as best performance – and features high levels of efficiency and productivity. The integrated web server simplifies starting up and speeds up maintenance

work. The distinctive features include lean planning, simple installation, fast start-up and the avoidance of downtimes. As installation can be carried out without the need for tools, and the cabling is pre-assembled, a reliable installation can be conducted much faster in the switch cabinet as well as on the machine and system. The single row connection level facilitates ease of wiring, installation and service. The plug-in connection level allows for the quick and safe connection of sensors and actuators with pre-assembled cables while simultaneously minimising the error rate in the system wiring. Thanks to its very slim modular design of just 11.5 mm module width and a low number of power-feed modules, switch cabinets with “u-remote” can be designed significantly smaller while increasing flexibility in their layout.
A component can be replaced load-free during operation, i.e. without having to interrupt the bus connection and disconnect the power supply. “u-remote”

easier, machine builders can use a standard USB connection for uploading and downloading drive- configuration files. They also can program the drive through its built-in human interface module (HIM), which displays data on the drive’s LCD with scrolling QuickView text and detailed explanations of parameters and other codes. The HIM also has multiple language options to address global needs. Unique to the PowerFlex 520-Series AC drives, AppView and CustomView tools help speed up configuration by providing groups of parameters for common applications and by allowing users to save their settings to new parameter groups. These tools can be easily accessible via the HIM, as well as configuration software tools.

has two features that make it stand out as best in class: Firstly, it separates the supply for inputs and outputs with two 10-A current paths capable of handling heavy loads – this reduces the number of power-feed modules needed and at the same time saves space as well as planning and maintenance effort. Secondly, it has an internal supply path capable of handling heavy loads, which allows 64 modules to be operated with just one power supply on the coupler. The “u-remote” I/O system has freely selectable sensor connection options
(2-, 3-, 4-conductor technology), and can be operated in a temperature range from -20°C to +60°C. The high-speed system bus provides impressive electronic performance and works with as many as 256 DI/DOs in 20 µs. LEDs on the module and each channel, directly positioned on the conductor connection, are extremely helpful for reading statuses and diagnoses. Protection again mismatched connections thanks to 64+4 coding, a wide range of marking options, a professional software tool for planning and checking the I/O station, and much more enhance the perfectly attuned system.
