Pilz PNOZ s30 safety relay

The Pilz PNOZ s30 safety relay monitors safe standstill, speed and direction of rotation. Safe working practices with the safety gate open, reduced set-up times and rapid access to the machine once standstill is initiated are the intended benefits for users.

The PNOZ s30 is suitable for all common motor feedback systems and proximity switches and is also easy to operate via a rotary knob. In conjunction with the monochrome display, time is saved during commissioning and when units are exchanged, as there’s no need for separate software. The display shows the set limit values and parameters as well as the current speed.

If a set warning threshold is reached, the speed monitor sends advance warning to the motor control system. This way it is possible to avoid unnecessary shutdown processes or hard shutdowns.

Parameters for standstill, speed and direction of rotation can be set freely on the PNOZ s30. Axis position monitoring can also be selected for standstill detection. The absolute position of the axis is safely monitored, thus protecting against unwanted axis movements in set-up mode, for example. The parameters for an application are stored on the corresponding chip card and can easily be transferred from one unit to another. The parameter data is password protected to make it safe from manipulation or unintended changes.
