ABB XZC826A102 (3BHE036348R0102) – Control/Interface Module for ABB Industrial Systems

The ABB XZC826A102, part number 3BHE036348R0102, is a genuine ABB board-level module typically used as a control/interface component within ABB drive and DCS cabinets. From my experience, this model serves as a direct, plug-in replacement in ABB backplane/rack assemblies, restoring system communications and logic functions without reworking the cabinet. You might notice that it’s labeled both by the functional code “XZC826A102” and ABB’s material number “3BHE036348R0102” — they refer to the same piece of hardware.

Company’s Order Placement Process and Guarantees

Key Features

• Direct drop-in replacement – Designed to fit ABB racks/backplanes that call for XZC826A102 / 3BHE036348R0102, minimizing downtime.
• Backplane-powered design – Power is typically supplied through the system backplane, which keeps wiring clean and reliable.
• Stable operation – Appears to be engineered for 24/7 industrial duty; in many cases runs reliably in 0–55°C control cabinets.
• Status indication – Usually features onboard status LEDs for quick diagnostics, useful during commissioning or fault finding.
• Firmware/logic compatibility – Matches ABB system firmware levels; helps avoid nuisance comms faults after replacement.
• ESD-safe connectors – Board-edge and mezzanine connectors are typically protected; handle with proper ESD procedures.

Technical Specifications

Application Fields

The XZC826A102 is commonly found in ABB industrial automation and drive systems used across:

• Metals and mining – control/communications boards inside MV drive cabinets
• Pulp & paper – DCS nodes and drive trains for web handling
• Power generation & utilities – excitation and auxiliary process control frames
• Oil & gas, chemicals – cabinet-based control where ABB racks are standard

A maintenance lead at a cement plant told us this module slotted into an ABB drive rack and cleared a communication fault within an hour, which seems to be a typical outcome when the legacy board fails intermittently.

Advantages & Value

• Reliability – Genuine ABB hardware typically improves MTBF compared to generic substitutes.
• Compatibility – Correct part number and revision reduce firmware mismatches and reengineering risk.
• Cost control – Swap-in replacement avoids costly controller or cabinet upgrades.
• Traceability – Clear mapping: XZC826A102 = 3BHE036348R0102 for procurement and maintenance records.
• Support – We can assist with pre-checks (photos/labels) and basic commissioning tips to speed up installation.

Installation & Maintenance

• Cabinet & mounting – Install in a clean, ventilated control cabinet (IEC/EN compliant). Keep ambient within 0–55°C and humidity non-condensing.
• ESD handling – Use grounded wrist straps and antistatic packaging. Avoid touching components and connector pins.
• Wiring – Seat the board fully in the ABB backplane; secure any retention levers. Confirm correct keying before power-up.
• Grounding & noise – Maintain cabinet grounding and segregation from high-power cables to reduce EMI.
• Routine care – Dust with dry, oil-free air periodically; back up parameters/firmware as per site policy; check status LEDs and diagnostics during PM rounds.
• Firmware alignment – Match firmware and configuration to your controller revision; a quick compatibility check usually avoids nuisance alarms.

Quality & Certifications

• CE marking and RoHS compliance typically applicable for ABB control modules
• Manufactured under ISO 9001 quality systems (manufacturer level)
• Covered by our 365-day warranty; each unit is inspected and packed to ESD/electronics standards before shipment
