Product Description

INTERBUS ST standard bus terminal modulesThe INTERBUS bus terminal module connects the input/output modules of an ST station

with the INTERBUS network.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
