Wieland Electric’s motor starter is designed to reduce the complexity of installation and improve the safety of conveyor systems. The podis MS 5HP is a compact, robust and user-friendly drive component with an integrated safe torque off (STO) function. The safety function disconnects the power supply from the emergency-stop circuits completely. As a result, the STO circuits no longer need routing through a central distributor and assignment to a specific energy branch. The system is less susceptible to interference and the installation work is more easily planned and carried out. The combination of starter functions allows for the decentralized assignment of all of the energy of the STO circuits in the field. In addition, a superior level of safety (SIL 3, PL e) can be achieved with less effort. All the motor starters in an emergency-stop circuit connect to the STO female sockets. The STO circuit monitors and operates through an auxiliary voltage generated in the field and also by a two-channel safety relay. Several STO circuits can operate from one power supply. Using an energy bus system such as the podis 5G6 from Wieland Electric further enhances decentralized motor control. The energy distribution for several motors and starters can combine on one line with only a single feed. The podis MS 5HP covers motors with a power range from 0.3 hp to 5 hp (0.25 kW to 4.0 kW), up to five different motors.
