Product Precautions
- ABB BCU-12 3AUA0000110430 links converter modules to the drive control program. Its optical branches and removable memory support coordinated converter control and fault analysis.
Product type: Converter control unit
Optical connections: Seven, V1–V7
Power input: 24 V DC ±10%, 2 A at XPOW
Optical connections: Seven, V1–V7
Power input: 24 V DC ±10%, 2 A at XPOW
BCU-12 provides seven fiber-optic converter connections. Its BPEB-05 expansion board adds five branches to the two basic connections, while integrated branching functionality collects converter data on an SDHC card for service analysis. Optical pairs connected to the same control unit must have equal lengths; the supported cable limit depends on fiber construction.
The control interfaces include six digital inputs, two configurable digital inputs/outputs, two differential analog inputs, two analog outputs and three relay outputs. Analog inputs support −10 to +10 V or −20 to +20 mA selection; analog outputs provide 0–20 mA into a load below 500 ohms. XPOW accepts two external 24 V DC supplies for redundancy.
Three option slots accept applicable F-type adapters or I/O extensions, with an additional RDCO communication option position. The converter memory unit is separate from the SDHC diagnostic card and must not be exchanged while powered. Units using BCON-12 revision R or later require a firmware and bootloader compatibility review; the physical BCU-12 identity alone does not establish compatibility with an older drive.
