Isolator for GPIOs - SIL certified

Hi TI team,

Currently we are planning to design a SIL-2 certified safety system. The system has some IOs that are going to be interfaced with a motor control system. In order to provide proper isolation we are in need of isolation drivers. Operating voltages are around 28V max and the max current consumption is around 1A. 

Can you please help in suggesting a suitable component that meets the safety requirement.
