SB302 - S
Isolated Fieldbus Entity Safety Barrier

The SB302-S uses Intrinsically Safe (I.S.) technology to completely isolate the control network on the hazardous side of the barrier. It supplies up to 60mA to field devices located in the hazardous area.

The incorporated repeater (operating in compliance with IEC 1158-2 specifications at 31.25 Kbits/s) cleans and boosts the incoming communication signal, transmitting it to instruments inside the hazardous environment without

compromising the safety requirements of explosion proof wiring. The networks on the hazardous and safe sides of the SB302-S are completely independent of each other.

The SB302-S also incorporates bus termination for the hazardous network in its design so that only one far terminator is required and up to a 2.5 mm2 (12 AWG) conductor can be used.
