Description Product Introduction The ABB TINT-4331 is a power interface board—sometimes called the AINT (Analog Interface) board—that lives inside the power section of an ACS800 drive. It sits between the RMIO control board (the brains) and the IGBT power module (the muscles). This board takes the fiber-optic signals from the RMIO, converts them into gate drive signals, and fires the IGBTs that switch the DC bus voltage to the motor. It also monitors the DC bus voltage, heatsink temperature, and current feedback. What makes the ABB TINT-4331 critical is its role in the drive’s protection scheme. If this board fails, the drive won’t run—or worse, it may fire IGBTs out of sequence and blow the power module. The TINT-4331 is used in ACS800 frames R5, R6, and R7. In my experience, these boards are reliable but not immortal. They fail most often from thermal stress or from a shorted IGBT that sends a fault current back through the gate driver. When you replace a blown IGBT module, replace the TINT-4331 at the same time. A damaged gate driver will kill the new IGBT in short order. Key Technical Specifications Parameter Specification Model ABB TINT-4331 Series ACS800 Board Type Power Interface / Gate Driver (AINT series) Communication Fiber-optic (DDCS) from RMIO control board Gate Drive Outputs 6 (for 3-phase IGBT module) Gate Drive Voltage Typically 15 V / -8 V (turn-on / turn-off) Monitoring DC bus voltage, phase currents, heatsink temperature Protection Desaturation detection, short-circuit protection, undervoltage lockout Status Indication LEDs for power, gate enable, fault Power Supply 24 VDC from drive auxiliary supply Mounting ACS800 power section (R5, R6, R7 frames) Operating Temp -10°C to 70°C Compatibility ACS800 R5, R6, R7 frames; certain ACS800 liquid-cooled variants Firmware / Software Versions & Upgrade Notes The ABB TINT-4331 contains no firmware. It is a hardware-only interface board. No configuration, no programming, no firmware upgrades. Installation: The board mounts inside the drive’s power section, typically on a standoff above the IGBT module. Fiber-optic cables connect to the RMIO control board. Power supply and gate drive connections are made via ribbon cables or direct pin connectors. Hardware revisions: The TINT-4331 is a specific revision of the AINT board family. Other variants include AINT-02C, AINT-03C, etc. The TINT-4331 is the version used in certain frame sizes and power ratings. Check your drive’s spare parts list before ordering. Field note: The ABB TINT-4331 has a specific fiber-optic cable routing. The cables must be routed away from high-power cables to prevent electromagnetic interference. I’ve seen drives that ran fine until a new TINT board was installed with cables draped over the DC bus bars—intermittent gate drive faults followed. Route the fiber away from high-voltage areas. Compatibility & Replacement Matrix Original Model Replacement Model Compatibility Level Key Notes ABB AINT-02C ABB TINT-4331 Drop-in (with frame check) Same functional board. The TINT-4331 is a specific revision for R5–R7 frames. Check compatibility with your drive. ABB AINT-03C Needs adaptation AINT-03C is for larger frames (R8). Not directly interchangeable. (same) Drop-in Direct replacement. Any TINT-4331 revision is interchangeable. ABB AINT-01C (older) Drop-in (with cable check) AINT-01C was used in R5/R6 frames. The is the later revision. Ribbon cables may differ—transfer the original cables. Third-party gate driver board Incompatible No substitute. The gate drive timing and fiber-optic protocol are proprietary to ABB. Frequently Asked Questions Q: What ACS800 frames use the ? The is used in frames R5, R6, and R7. These are typically drives in the 55 kW to 315 kW range (depending on voltage). It does not fit R2–R4 frames (smaller drives) or R8 frames (larger drives). Check your drive’s type code to confirm. Q: What’s the difference between AINT and TINT boards? AINT (Analog Interface) is the generic name for the power interface board family. TINT is a specific revision or variant within that family. The is functionally equivalent to an AINT-02C but with specific component selections for certain power ratings. In practice, they are interchangeable in the same frame size. Q: My drive shows “IGBT FAULT” or “SHORT CIRCUIT.” Is this board bad? Possibly. An “IGBT FAULT” on an often indicates a gate drive failure or a shorted IGBT. The has desaturation detection that trips if the IGBT doesn’t turn on properly. If you’ve already replaced the IGBT module and still get the fault, the TINT board is the likely culprit. Replace it. Q: How do I test this board outside the drive? You can’t fully test the without the drive. Basic checks: visually inspect for burned components, bulging capacitors, or cracked solder joints. You can also check the fiber-optic connectors for cleanliness—dust on the fiber ends can cause communication loss. Beyond that, install it in a known-good drive and test. Q: What happens if the fiber-optic cables are swapped? The has two fiber-optic connections: one for transmit (TX) and one for receive (RX). If you swap them, the drive will show a “COMM LOSS” or “BOARD FAULT” because the RMIO board can’t communicate with the power section. The fiber connectors are usually labeled—match TX to RX and RX to TX between the boards. Q: My drive runs but trips on overcurrent intermittently. Could the TINT board cause that? Yes. If the has a damaged current feedback circuit, it can send incorrect current values to the RMIO. The drive then trips on overcurrent even though the actual motor current is fine. This is a common failure mode. Replace the board. Q: Do I need to recalibrate anything after replacing this board? No. The has no calibration parameters. The drive’s current and voltage scaling are handled by the RMIO control board using feedback from the TINT board’s sensors. The board is plug-and-play—no software configuration required. Q: What’s the typical lifespan of this board? In a well-cooled drive (clean filters, proper ambient temperature), the can last 10–15 years. In harsh environments (high temperature, dusty, high vibration), failure rates increase. The most common failure is electrolytic capacitor aging in the gate drive power supply section. If your drive is over 10 years old, consider replacing the TINT board proactively when you do major maintenance.
