The Bihl+Wiedemann BWU1569 is an AS-i 3.0 PROFIBUS Gateway housed in a stainless steel enclosure, designed for use in industrial automation systems requiring integration between AS-Interface field networks and PROFIBUS control architectures. The unit operates as a 2-master gateway, supporting two AS-i circuits from a single integrated power supply rated at 30V (6W) per AS-i network. The AS-Interface positive rail is rated at 30V while the negative rail is referenced to 0V. Communication with the PROFIBUS network is handled via an RS485 interface, and the unit also includes an RS232 port for diagnostic and configuration access.
Key features visible on the nameplate include duplicate address recognition and an integrated AS-i fault detector, both of which support network integrity monitoring in field installations. The front panel includes an LCD display, four control buttons (ESC, Mode, Set, OK), and a row of LED status indicators covering power, PROFIBUS status, configuration error, AS-i voltage status, AS-i active state, programming enable, and primary mode. Terminal connections on the unit provide for two separate AS-i circuit inputs (ASI1 and ASI2) plus an auxiliary power connection.
The unit carries UL listing (IND.CONT.EQ., file 1HD8) and CE marking. It is manufactured by Bihl+Wiedemann GmbH of Germany. Article number BWU1569, Ident No. 12147. The BWU2546 is listed by the manufacturer as the successor model to this unit.
