With its new VARIO I/O modules, PMA in Kassel now offers maximum flexibility for decentralized installation of I/O circuits plus high adaptability to the most varied applications in the areas of machine and plant engineering, the auto-motive industry, as well as process, energy, traffic and building automation.

Connection of the VARIO system to various PLC or PC-based automation solutions presents no problems, thanks to the Ethernet-ModTCP bus-coupler module, whereby the module also provides the system's energization.

Any number of digital and analog I/O modules, each with 2 to 16 channels, can be connected to the bus coupler, thus providing optimum modularity for every application.

Beside the VARIO system the modular multi-channel controller system KS Vario is also available.
