The modular, manageable switch system from the phoenix contact factory line range enables industrial use ethernet applications for automation systems. The modular manageable switch [mms] consists of a head station and up to two side-by-side mounting expansion modules. Each unit can take up to a maximum of eight ports. This enables expansion stages from eight to 24 ports. For the first time, advanced modular two-port interface modules provide a flexible cable connection, alternatively facing down or to the front, and designed respectively for twisted pair, glass fibre or polymer and hcs [hard cald silica] cables. The compact design with a depth of 110 mm provides flexibility when choosing the installation environment - whether this is a control cabinet or decentralised control boxes. The robust switch not only meets all industry standards regarding emc and mechanical loads, it is also designed with vibration-proof push-pull locking to the rj-45 standard. Management functions including web based management [wbm] and simple network management protocol [snmp] makes configuration, set-up and diagnostics easier.
