Allen-Bradley 2090-XNSM-M 4G Terminal Head 4G

Product Dimensions：

The Allen-Bradley 2090-XNSM-M is a high-performance External Shunt Module designed for use with Kinetix servo drives (primarily the Kinetix 6000 and 6200 series). It provides the necessary power dissipation for applications where the drive’s internal shunt capacity is insufficient to handle regenerative energy.

1. Product Description

The 2090-XNSM-M is a passive power component that connects to the DC bus of a servo drive. When a motor decelerates rapidly, it acts as a generator, sending energy back to the drive. This module absorbs that excess energy and dissipates it as heat, preventing “Overvoltage” faults and protecting the drive’s internal circuitry.

3. Product Advantages

• Enhanced Deceleration: Allows for much faster stopping times and more aggressive motion profiles without triggering DC bus faults.

• Thermal Protection: Built-in thermostat contacts allow the drive or a PLC to monitor the module’s temperature, preventing fire hazards or equipment damage.

• Space Efficient: Designed with a compact footprint to fit into standard industrial control cabinets alongside the drives.

• Reliability: Robust construction ensures a long service life even in high-duty cycle applications.

4. Key Considerations & Safety

• Heat Generation: This module is designed to get hot. Ensure it is mounted in a location with adequate airflow and away from heat-sensitive components (like plastic wire ducting).

• Wiring: Use high-temperature rated wire for the shunt connections. Ensure the “Thermal Switch” (TS) terminals are integrated into your safety or control circuit.

• Fusing: Proper branch circuit protection should be used according to local electrical codes and the Kinetix drive manual.

• Clearance: Maintain the manufacturer-specified minimum clearance (usually several inches) above and below the module for convection cooling.

5. Typical Applications

The 2090-XNSM-M is essential in scenarios involving:

• High Inertia Loads: Large flywheels or heavy mechanical arms that carry significant kinetic energy.

• Rapid Cycling: Applications that require frequent, fast starts and stops (e.g., high-speed packaging or pick-and-place).

• Vertical Loads: Hoists or elevators where gravity causes the motor to regenerate power during the descent.
