Weidmüller’s ‘u-remote’ is a modularly designed remote I/O system with plug-in connection level designed to save space in the switch cabinet thanks to high channel density. All advantages focus directly on the users: the system is distinguished by high component density and features high levels of efficiency and productivity. The integrated Web server simplifies start-up and speeds up maintenance work. Other distinctive features include lean planning, simple installation, fast start-up and the avoidance of downtime.
As installation can be carried out without the need for tools as the cabling is pre-assembled, allowing reliable installation to be conducted 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 preassembled cables while simultaneously minimising the error rate in the system wiring.
Slim modular design
Thanks to its slim modular design of just 11,5 mm 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’ has two features that set it apart. First, 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. And second, ‘u-remote’ 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 and 4-conductor technology). It can be operated in a temperature range from -20 to 60°C. The high-speed system bus works with as many as 256 DI/DOs in 20 µs, while LEDs, directly positioned on the conductor connection, are extremely helpful for reading status and diagnostics.
Protection against mismatched connections thanks to 64+4 coding, a wide range of marking options and a professional software tool for planning and checking the I/O enhance the perfectly attuned system
