Safety module for sensorless standstill detection

K.A. Schmersal

With the SSW303HV, the Schmersal Group is now introducing a new sensorless standstill monitor. The SSW303HV only takes up 45 mm width in the control cabinet. The plug-in and coded connection terminals create the prerequisites for quick and error-free installation. An additional signal contact provides information about the error status of the block.

Since the standstill monitor works without sensors, the machine designer does not have to intervene in the "hardware" of the surrounding construction. The safety module is connected directly to a three-phase three-phase motor and measures the frequency of the induced voltage directly - with rated motor voltages of up to 690V. The safety contacts for releasing an interlocking device close as soon as the motor comes to a standstill.

The SSW 303HV can be used in safety circuits up to Category 4 / Performance Level e according to EN 13849-1 and SIL 3 according to EN IEC 61508 - with all common types of solenoid interlocks from the relevant manufacturers.
