LioN, a line of compact I/O modules for DeviceNet and Profibus-DP applications, is comprised of two housing styles, the LioN-S and the LioN-M. LioN-S units have ultra-compact housings with pico (M8) I/O and micro (M12) power and bus connectors. They are available in eight-channel versions. LioN-M units have compact housings with micro (M12) and mini (7/8 in.) power connectors. Features include universal I/O functionality, expanded diagnostics capabilities, diagnostic LEDs, optimized spacing between ports, flexible mounting options, and an un-potted design which makes it possible to achieve the same shock and vibration resistance that was until now only possible with potted modules.
