11. The four channel digital transmitter type SILBUS TX4D has been awarded IECEx certification under IECEx TSA 07 0002 Ex ia I as part of the Dupline SILBUS system The certification requires that the SILBUS TX4D be mounted within a host enclosure that provides a minimum ingress protection of IP54 IP55 for Queensland Australia Because of the segregation and isolation between the various ports of the SILBUS TX4D it may be used in three different installation configurations that offer considerable flexibility in its application when dealing with intrinsically safe and non intrinsically safe circuits As shown in the figure below the three major port areas are segregated from each other to 1 60079 11 375 volts as indicated by the green dotted lines The four digital input channels are further segregated from each other to IEC 60079 11 30 volts as indicated by the magenta dotted lines SIG 1 2 2 2 Me CH2 J 290 gt cus 29 Qn 52 zo 22 a o CH4 o lt tr 140 15 Figure 2 SILBUS TX4D segregation and isolation levels The digital input terminals the SILBUS network terminals and the power port terminals are all separated from each other by more than 50mm The individual digital input channels are separated from each other by more than 6mm These segregations and separations combine to allow the followi
