Schmersal SSW300HV sensorless standstill monitor

Tuesday, 15 June, 2021 | Supplied by: Control Logic Pty Ltd


The Schmersal SSW300HV is a sensorless standstill monitor developed with a wide-range power supply for all common AC and DC operating voltages, from 24 VDC and 24 VAC to 230 VAC. As a universal device it replaces 14 variants of the previous range, making product selection and spares management simpler.

The product is compact at 45 mm wide and has pluggable, coded connecting terminals for rapid, error-free installation, while an additional signalling contact provides information on the error status of the module for control system integration. The operating temperature range is -25 to +55°C, which increases potential installation in harsh locations.

The standstill monitor operates entirely without sensors, so no allowance or space is required for mounting external sensors. The safety module is connected directly to a three-phase motor and directly measures the frequency of the induced voltage for rated motor voltages of up to 690 V. The safety contacts open as soon as the motor comes to a standstill.

The device can be used in safety circuits up to category 4/PL e in accordance with EN 13849-1 and SIL 3 in accordance with EN IEC 61508.
