Introduction to CONVERTEAM PIB671-1500
Product Description
The CONVERTEAM PIB671-1500 is a high-performance power interface module designed for industrial drive systems, serving as a critical link between power sources, motor drives, and control systems. Developed by Converteam (now part of General Electric’s Power Conversion division), this module is engineered to handle high current levels and ensure stable power distribution in heavy-duty applications such as steel mills, mining equipment, marine propulsion systems, and large-scale industrial machinery.
Featuring robust power electronics and advanced protection mechanisms, the PIB671-1500 efficiently manages power flow, converts voltage levels where necessary, and safeguards connected equipment against electrical anomalies like overcurrent, overvoltage, and short circuits. Its modular design allows for easy integration into existing drive systems, while its compact form factor makes it suitable for space-constrained installations. With a focus on reliability and durability, this module operates seamlessly in harsh industrial environments, ensuring uninterrupted performance even under extreme temperatures and vibration.

-
- Connect the output terminals to the motor drive or load, ensuring phase alignment and proper insulation.
-
- Wire the control signals (start/stop, fault reset) to the low-voltage terminal block, using shielded twisted-pair cables for noise immunity.
-
- Establish communication links via RS485 or Ethernet, configuring baud rate (9600-115200 bps for RS485) and IP address as needed.
- Configuration and Commissioning:
-
- Power on the module and use the Converteam PowerSuite software to configure parameters such as current limits, trip delays, and communication settings.
-
- Perform a functional test by applying a low-power signal to verify input/output operation and protection responses.
-
- Calibrate current sensors using the software to ensure accurate measurement and protection.
- Operation and Maintenance:
-
- Monitor module status via the front-panel LED indicators (power, fault, communication) or remote software.
-
- Inspect cooling system flow and pressure daily to prevent overheating.
-
- Check electrical connections quarterly for tightness and signs of corrosion.
-
- Perform annual insulation resistance tests (minimum 100 MΩ at 1000 V DC) to ensure dielectric integrity.
-
- Replace air filters in the cooling system every 6 months or as needed based on environmental conditions.
System Introduction
The CONVERTEAM PIB671-1500 functions as a critical power management node within industrial drive systems, integrating with three key subsystems:
- Power Input Layer: Receives high-voltage AC power from the mains or generator, conditioning it to meet the requirements of downstream drives.
- Control Layer: Communicates with the system PLC or drive controller via digital interfaces, receiving commands and transmitting status data (current, voltage, temperature).
- Protection Layer: Continuously monitors electrical parameters and activates protective mechanisms (e.g., crowbar circuits, contactor trips) to isolate faults and prevent equipment damage.
In a typical steel mill application, the PIB671-1500 connects the main power grid to a rolling mill drive, regulating power flow to the motor while protecting against overloads during peak operation. It communicates with the mill’s central control system to coordinate speed changes and shutdowns, ensuring safe and efficient production.
