Bihl+Wiedemann BWU2427 Bihl+Wiedemann AS-Interface Gateways and Safety Monitors

Razz Middle East supplies Bihl+Wiedemann AS-Interface hardware in Saudi Arabia, sourced to order and delivered duty-paid to site. The range covers AS-i gateways to the common industrial fieldbuses, integrated safety monitors, AS-i power supplies and I/O modules. Every device carries a BWU order number such as BWU2238 on its label, and that number is what a quotation is built from.

This page covers Bihl+Wiedemann part number BWU2427 — Bihl+Wiedemann AS-Interface Gateways and Safety Monitors. Quote the full part number with your enquiry and the item is unambiguous: one part number identifies one exact product variant, including options that are not visible in the description.

About Bihl+Wiedemann AS-Interface Gateways and Safety Monitors

AS-Interface is a two-wire network that carries both data and device power on one flat cable, which is why it is used where a machine has many simple sensors and actuators spread over a long distance. A gateway is the head of that network: it acts as AS-i master on one side and speaks PROFINET, EtherNet/IP, PROFIBUS, EtherCAT or Modbus TCP to the controller on the other, in single-master and double-master versions. Many gateways include a safety monitor in the same housing, which evaluates safe input slaves such as emergency stops and guard switches on the AS-i line and drives safe outputs, so functional safety runs over the same cable as the standard I/O without a separate safety bus. The rest of the range fills in around that: AS-i power supplies and data decoupling, and standard and safe I/O modules for field mounting. The BWU number is the definitive identifier, because the same functional description often covers several hardware and firmware variants with different BWU numbers.

Bihl+Wiedemann AS-Interface Gateways and Safety Monitors in Saudi Arabia

In Saudi plants AS-i earns its place where the wiring distance is the problem. Bottling and packaging lines in food and beverage factories use it for conveyor sensors, valve actuators and pull-wire emergency stops along the length of a line. Cement plants and bulk terminals use it on long belt conveyors, where a single flat cable running beside the belt replaces a large bundle of individual sensor runs back to the panel. Water and wastewater treatment sites use it on valve and penstock actuator groups. The network runs on its own nominal 30 V supply, independent of the 380/400 V 60 Hz plant distribution. In Saudi ambient conditions the practical failure points are the cable piercing connections and field module seals, so field modules should be selected for the wash-down or dust exposure they will actually see.

Ordering and lead time

Read the BWU number from the device label and quote it as it appears, because the printed functional description on its own covers several variants. For a gateway, state which fieldbus the controller uses, whether you need one or two AS-i masters, and whether the integrated safety monitor is required and how many safe output circuits it must drive. For safe I/O, state the number of safe inputs per module and the mounting arrangement. For power supplies, state the AS-i current the circuit draws. If you are replacing a failed unit, note the firmware version on the label as well, since a configuration file from the old gateway may not load into a newer variant. Lead time is about three weeks, delivered duty-paid.
