Description

Hardware & Electrical Specifications

• Model：XVC768115
• Part Number：3BHB007211R115，Reference PN：3BHB007211R102
• Module Type：Current Measurement Monitoring Board
• Bus Interface：Internal converter system back‑plane signal bus
• Signal Channel：Multi‑phase current sampling input channels, analog measuring output channels
• Power supply：24 V DC (18‑32 V DC)
• Max power consumption：11 W
• Galvanic isolation：≥2500 V AC between power‑unit sampling side and control‑logic side
• Dielectric strength：2500 V AC 1 minute
• Insulation resistance：＞100 MΩ @ 500 V DC
• On‑board protection：ESD protection, multi‑stage surge suppression for current sampling circuit, analog filter circuit, hardware fault latch, conformal coated PCB
• Compatibility note：Cannot run standalone; dedicated for ACS6000 / Megadrive‑LCI converter rack, must match corresponding system firmware version. Direct swap with 3BHB007211R102 needs hardware‑firmware compatibility validation.

Main Functions

1. High‑precision acquisition, filtering and scaling conditioning for converter phase current signals.
2. Galvanic isolation between high‑power power section and low‑voltage control rack, suppress heavy electromagnetic interference.
3. Hardware‑level pre‑detection of over‑current fault, output fast fault trigger signal for protection trip.
4. Send processed current measuring data to main processor for closed‑loop current‑torque control and fault event recording.
5. Channel‑level self‑diagnosis: detect sampling‑circuit abnormality and board power‑supply failure, report fault codes to converter system.
6. LED status indication:
   • Green LED：Power supply normal, board logic healthy
   • Yellow LED：Current sampling signal active
   • Red LED：Sampling channel fault / over‑current pre‑alarm / board hardware fault

Installation & Wiring Requirements

1. Cut off cabinet total power before replacement. Insert XVC768115 into assigned rack slot and tighten mounting screws. Hot‑swap is strictly forbidden.
2. Connect current‑sampling cables strictly per wiring drawing; strictly separate high‑power cables and weak‑signal cables to reduce electromagnetic interference.
3. Cabinet protective grounding shall comply with ABB ACS6000 / Megadrive‑LCI grounding specification.
4. After replacement, confirm firmware compatibility, complete current‑sampling calibration and over‑current protection simulation test before commissioning.
5. Replacement note：Cross‑part‑number substitution with R102 version requires hardware‑firmware compatibility validation.
