Описание
This isolated barrier is used for intrinsic safety applications. It provides control and signal transfer for SMART compatible fire and smoke alarm transmitters inside hazardous areas. 2-channel isolated barrier, 24 V DC supply (loop powered), SMART fire alarm input, Current input 1 mA .. 20 mA, Up to SIL 3 acc. to IEC 61508, Transfer direction: to the control systempa. Digital signals may be superimposed on the analog values in the hazardous or safe area and are transferred bidirectionally. The fall time of the digital signal must be less than 50 μs, the current in the hazardous area must be bigger than 1 mA. Since this isolator is loop-powered, use the technical data to verify that proper voltage is available to the field devices.
