2、 Description
①MS6054DC signal input isolation safety barrier is used to isolate and limit the DC signal input connected to hazardous areas, convert it into standard process signals, and output them to the control system or other intelligent instruments in the safety zone.
②This isolated safety barrier requires independent power supply, with electromagnetic isolation between the power supply input circuit output circuit.
