Available from Moore Industries-Pacific , SPURBARRIER (SB Series) fieldbus device couplers’ function is to connect intrinsically-safe fieldbus devices to a non-intrinsically-safe (Ex e) trunk. Fieldbus device couplers are use to complete this function in FOUNDATION fieldbus (H1) and PROFIBUS PA networks.
SB Series fieldbus devices can be installed in Zones 1, 2, 21, 22 (IEC) and Class 1, Division 2 (NEC) areas. The fieldbus device couplers are FISCO and ENTITY specification compliant, and can offer up to 40mA to each of up to four intrinsically-safe spurs.
Fieldbus device couplers feature on-board LEDs that provide a visual sign of status and fault indication per spur.
SPURBARRIER fieldbus device couplers can be supplied for DIN-rail or wall-mounting. The fieldbus device couplers can also be supplied with a field enclosure made with IP66 Glass Reinforced Polyester (GRP) or Stainless Steel 316.
Bottom-mounted cable glands facilitate the cable entries on the enclosures.
