Depending on the transmission medium used, the bus terminal modules are equipped with different bus connections. For copper conductors, D-SUB and MINI-COMBICON connectors are available. The fiber optic versions are equipped with F-SMA connectors. The bus terminal modules are available in two different performance classes. A maximum of 4 or 8 input/output modules can be operated on one bus terminal module. The bus terminal module takes on the following functions within a modular INTERBUS-ST station: - Refreshing the INTERBUS remote bus signals - Electrical isolation of the remote bus segments - Decoupling of the outgoing remote bus or of the connected input/ output modules from the INTERBUS network with a software command - Supply of the connected input/output modules with an electrically isolated voltage supply from an integrated power supply unit     Key commercial data Packing unit 1 pc GTIN Weight per Piece (excluding packing) 256.2 GRM Custom tariff number 85389091 Country of origin Germany Technical data Dimensions Width 44 mm Height 117 mm Length 116 mm 09/08/2014   Page 1 / 4 https://www.phoenixcontact.com/us/products/2750963 Bus coupler - IBS ST 24 BKM-LK - 2750963 Technical data Ambient conditions Degree of protection IP20 Interfaces Interface INTERBUS remote bus (incoming/outgoing) Connection method 4x F-SMA connector Transmission speed 500 kBit/s Interface ST local bus Connection method ST local bus connector Transmission speed 500 kBit/s Power supply Communications supply 9 V DC Typical current consumption 70 mA (without connected ST I/O modules) Max. current consumption 300 mA (for max. terminal configuration) 500 mA (of all I/O modules max.)
