170 BNO 681 00

Electrical Functions of the Branch interface module 170 BNO 681 00

Supply The supply voltage is UB = 24 VDC.

The logical supply (VCC = 5 VDC) is created from the 24 VDC. It is monitored. If the

voltage is in the tolerance range, a green LED will be switched on (ready). If the

voltage falls outside tolerance, a reset will be triggered.

Interfaces The bus terminal has three INTERBUS interfaces. The incoming and outgoing

interfaces are designed for the connection of fiber optic cables. The remote bus

branch is connected using a 9 pin DSUB plug. This interface is suitable for the use

of OPTOSUB.

The user of the module must establish decide if it is the last node at the remote bus,

using an end identification slide switch.

Peripheral

Signals

The terminals of the terminal block include a reconfiguration button, with which the

remote bus branch can be reconnected.

A relay output is also available, which can indicate an error at the remote bus

branch. The relay contacts are change over contacts.
