INTERBUS Loop 1 INTERBUS Loop Product Description INTERBUS Loop modules are designed for remote use on machines or in systems. INTERBUS Loop devices are connected to INTERBUS by a bus terminal module (BK module). The modules are connected through an unshielded, 2-wire cable that supplies power and transmits data.
Page 8
IBSL SYS PRO UM E I/O connection The inputs/outputs are connected to the I/O modules using 5-pos. M12 connectors. The sensors can be connected using the 4-wire connection method (signal, , 0 V, functional earth ground). The actuators can be connected using the 3-wire connection method (signal, 0 V, functional earth ground).
INTERBUS Loop Installation Example Figure 1-1 Electrical installation example Mount the modules on a grounded mounting plate. The modules are grounded by the mounting screw. Cover unused sensor/actuator sockets with protective caps (accessories) to ensure IP 65/IP 67 protection. Cover the unused connections for the actuator supply with filler plugs (supplied as standard) and tighten the cap nut to ensure IP 65/IP 67 protection.

IBSL SYS PRO UM E Diagnostic and Status Indicators The diagnostic and status indicators of the module allow for quick local error diagnostics. The LEDs listed below are typical for INTERBUS Loop modules, but not all of the LEDs are on every module. Depending on the module type, additional indicators can also indicate the status of the module.

INTERBUS Loop Mounting Distances BK modules with IP 20 protection are mounted on mounting rails inside the enclosure. I/O modules and BK modules with IP 65/IP 67 protection are mounted directly on mounting angles or mounting plates. 1.5.1 Mounting Distances for BK Modules With IP 20 Protection Keep at least 50 mm (1.969 in.) free, above and below the BK module, for ventilation and cabling.

Page 36
IBSL SYS PRO UM E To avoid mixing up IN and OUT connections of the installation local bus, the splice ring keying for the incoming installation local bus (IN) is circular and the splice ring keying for the outgoing installation local bus (OUT) is square.
Page 37
INTERBUS Loop 1.8.6 Connecting the Installation Local Bus (Modules) The connecting cable types depend on the module type. – For modules that have only inputs you need a two-wire installation local bus cable (Figure 1-28, A1). – For modules with outputs you need in addition a three-wire cable for the actuator supply (Figure 1-28, A2).
Page 38
IBSL SYS PRO UM E Ensure you select the correct individual parts for assembling the cable. The cap nuts have different colors. The assembly steps are identical for two-wire and three-wire installation local bus cables. • Push the cap nut (1), the compression ring (4) and the grommet (2 or 6) onto the cable (Figure 1-28, A1 and A2).
