Machine speed monitor

A safety relay that monitors the safe standstill, over-speed and direction of rotation of a variety of machines is now available from Pilz Automation Technology. The PNOZ s30 speed monitor can be used for applications from small packaging machines to large rotating machinery as used, for example, in paper mills and web-based printing machines.

In accordance with the new Machinery Directive, when a machine drive is brought to a standstill, the operating status must be safely monitored and maintained.

Part of Pilz Automation Technology's PNOZsigma range, the PNOZ s30 can be connected to many motor feedback systems which use incremental encoders or proximity sensors to provide a speed signal. A rotary knob with key function (push and turn) and an integrated display enable users to enter their own data via an intuitive menu structure. These parameters are stored on a chip card. The permanent display informs users about current speed during machine operation, while integrated LCDs show the state of the output relay.

Safety functions include standstill monitoring combined with safe position monitoring at standstill.
