The compact S-class controller
B&R presents its new Compact-S family of controllers within the X20 system. The new controllers combine 2 previously conflicting characteristics: They are both powerful and compact. Customers can choose between 5 different variants to get the product that best meets the requirements of the machine – technically and economically.
As standard, the new controllers are equipped with USB, POWERLINK and Gigabit Ethernet interfaces and are fully compatible with all other X20 controllers. The most powerful version of the Compact S-controllers achieves cycle times down to 400 µs and has 256 MB of RAM and 2 GB of internal flash memory.
If this performance is not needed, a variant with a maximum cycle time of 800 µs or 1 ms can also be selected. For machines that do not require a real-time network, the two smallest Compact-S variants can be used. They have Fast Ethernet and can achieve cycle times as low as 2 or 4 ms.
The new controllers have a width of only 37.5 mm, including the power supply, making them the most compact in their class. With POWERLINK, Ethernet, USB and RS232 as standard equipment, they offer ample communication options. A CAN interface is also available as an option without increasing the size. If the application requires additional interfaces, the controller can be modularly expanded by one or two X20 interface slots. This allows the entire product range of X20 fieldbus interfaces to be used.
