BIHL+WIEDEMANN BWU1840 / BWU1416 AS-Interface Master Module – BW Sensor/Actuator Interface Series
When an AS-Interface master module fails on the production floor, the entire sensor and actuator network goes silent. Conveyor lines halt, safety circuits lose their handshake, and diagnostic data vanishes — leaving engineers blind in a live plant environment. Every minute of unplanned downtime translates directly into lost throughput and costly emergency maintenance calls. The BIHL+WIEDEMANN BWU1840 / BWU1416 is the critical gateway that keeps your AS-i network alive, your field devices communicating, and your PLC in full command of the process.
Within the BIHL+WIEDEMANN BW AS-Interface product family, the BWU1840 and BWU1416 represent a dual-SKU master solution engineered for demanding industrial environments. BIHL+WIEDEMANN is globally recognized as a pioneer in AS-Interface technology, holding foundational patents and actively contributing to the AS-International Association standards. These modules are trusted by system integrators and OEMs across automotive, food & beverage, packaging, and material handling sectors worldwide.

Frequently Asked Questions
- Q: What is the difference between BWU1840 and BWU1416?
- A: Both are BIHL+WIEDEMANN AS-Interface master modules within the same product family. The exact functional differences (e.g., host interface variant, firmware version, or housing) should be confirmed via the official BIHL+WIEDEMANN datasheet. Contact us and we will provide the relevant documentation.
- Q: Is this module compatible with Siemens S7-1500?
- A: BIHL+WIEDEMANN AS-i masters with PROFINET interface are compatible with Siemens S7-1500 series PLCs. Please confirm the exact interface type of your required variant with our team before ordering.
- Q: Can I use this module in a Safety Integrity Level (SIL) application?
- A: AS-i Safety at Work (SaW) requires a dedicated safety monitor in addition to the master module. The BWU1840/BWU1416 master itself handles standard AS-i communication; safety functionality is managed by a separate BW safety monitor. Consult your safety engineer for SIL assessment.
- Q: What is the maximum cable length for the AS-i network?
- A: The standard AS-i cable length is 100 m per segment. With BIHL+WIEDEMANN repeaters, this can be extended to 300 m or more depending on network topology.
- Q: Do you provide a warranty?
- A: Yes. All modules supplied by Konmask.com carry a 12-month warranty against manufacturing defects. Extended warranty options are available — contact us for details.
