Application

The remote bus connection unit connects desk-top systems, as e. g. the OS 265-3 operation and monitoring system or SICOMP industry-standard PC to a redundant or non-redundant remote bus. Electrical isolation between the local and the remote buses is achieved at the same time. Non-redundant AC 230 V power supply.

Design

The remote bus connection unit consists of a housing for floor or wall mounting, 2 single-height subracks, a mounting rail, mains filter and power supply module for AC 50 Hz 230 V.

It provides space for the 2 bus converters (cf. page 4/9) re- quired to convert the 20-m local bus interface to the remote bus interface. The connector boards AF for converting the cable cross-section (cf. page 4/10) are also fitted into the remote bus connection unit. One connector board is required for each bus converter.

The remote bus connection unit can be fitted with a connection distributor for 20-m local bus for commissioning and servi- cing.This is an open local bus interface for intermediate connec- tion of e. g. a SICOMP industry-standard PC with PROGRAF AS/OS program package for central configuring.

The remote bus connection unit is connected to the interface module for 20-m local bus fitted in the system to be connected via a cable connector.
