SEW Eurodrive now offers the integrated S12 safety option for its decentralised MOVIFIT FC/MC drive units used in modular and flexible conveyor systems. Two option card versions – S12A and S12B – are available, supporting different numbers of safety-related inputs and outputs.
The S12 option offers the additional safety functions STO (safe torque off), SS1a/c (safe stop 1), SLS (safely limited speed) and SDI (safe direction) on top of the standard MOVIFIT functions. The SLS function can be easily applied using the EI7C (FS) simple encoder and without the need for any extra motor space.
A cost-effective, integrated safety solution, the S12 option can be used either independently or in slave mode. The inputs can also be set as 1- or 2-channel, and they can read OSSD (Output Signal Switching Device)-capable sensors such as light grids and scanners.
