ALSTOM PIB310 (3BHB0190) – Power Interface Board for Drive and Power Control Systems

The ALSTOM PIB310, often referenced under part code 3BHB0190, is a power interface board used between the control layer and the power stage in industrial drive systems. From my experience, it typically handles signal isolation, conditioning, and interlocking between the controller and the converter stack, making it a straightforward drop-in replacement when a legacy drive cabinet flags faults linked to interface circuitry. You might notice that it behaves like a bridge: it forwards commands, reads back status, and protects the system with hardware-level checks.

Company’s Order Placement Process and Guarantees

• Warranty: 365 days
• Delivery: 1 week if in stock; no more than 1 month at the latest
• Payment: 50% advance payment, full payment before delivery
• Express options: FedEx, UPS, DHL

Key Features

• Interface between control CPU and power stage – Routes firing commands, protection signals, and status feedback reliably.
• Isolation and signal conditioning – Typically includes galvanic isolation and filtering to protect upstream controllers.
• Backplane-powered and cabinet-integrated – Designed to slot into OEM racks for quick replacement and minimal rewiring.
• Robust for cabinet environments – Works in enclosed panels where temperature, airflow, and EMC are managed.
• Service-friendly design – From field feedback, technicians appreciate the plug-in form and straightforward terminal markings.

Technical Specifications

Application Fields

You’ll typically find the PIB310 inside medium-to-large drive cabinets where reliable coordination between the control board and the converter stack is mandatory. Common deployments include:

• Metals and mining: large fans, mills, and conveyors using legacy drive platforms
• Power and utilities: auxiliary drive systems and exciters in plant environments
• Oil & gas and petrochem: compressor drives and pump controls in MCC rooms
• Marine and heavy industry: high-inertia loads with stringent protection interlocks

Advantages & Value

• Form-fit-function replacement – Helps restore legacy systems quickly without redesigning control logic.
• Compatibility – Matches established ALSTOM/legacy architectures where 3BHB0190-coded boards are specified.
• Reduced downtime risk – One thing I appreciate is how these boards simplify fault isolation at the interface layer.
• Procurement-friendly – Fast lead times and a 365-day warranty support preventive swaps during planned outages.

A maintenance manager recently mentioned that swapping in a PIB310 during a scheduled shutdown cut their troubleshooting time in half, mainly because the interface signals came back into spec without touching the higher-level controller.

Installation & Maintenance

• Panel & environment – Install in a closed control cabinet with adequate ventilation; maintain ambient 0–55 °C, RH non-condensing.
• Wiring – Use the OEM backplane; verify connector orientation and locking hardware; keep signal wiring segregated from high-power cables.
• Safety – De-energize, lockout/tagout, discharge stored energy, and apply ESD precautions before handling.
• Commissioning – Check jumpers/dips (if present), confirm firmware compatibility if required by the system, and run built-in diagnostics.
• Routine care – Quarterly dust removal with dry air, visual inspection of connectors, verify tightness; review drive logs for intermittent interface faults.

Quality & Certifications

• Manufacturer quality systems: ISO 9001 (typical for production)
• Conformity: CE marking applicable at system level; component-level RoHS status may vary by manufacturing year
• Safety compliance: Used within certified cabinets; UL/CSA recognition generally pertains to the assembled panel
• Warranty: 365 days replacement/repair support

If you’re planning a like-for-like replacement, share the drive cabinet model and a photo of the existing slot. It helps confirm the PIB310 variant and avoids surprises with backplane revisions.
