Brand：SIEMENS Model number：6SE7090-0XX84-0KA0

Country of origin: Germany Product weight：0.55kg

HS code：8517623990

Product Details：

Product Dimensions：

The 6SE7090-0XX84-0KA0 board belongs to the legacy SIMOVERT MASTERDRIVES chassis and cabinet units. In large-scale industrial drives, these auxiliary option boards fit directly into dedicated option slots on the main control board (such as the CUVC or CUSVC control units). This module provides the necessary hardware connections and physical interfaces required to link the drive's central processing unit to external automation systems, fieldbus interfaces, or auxiliary feedback devices. It plays a critical role in preserving signal integrity across complex control architectures in multi-axis or heavy-duty drive systems.

Product Parameters

Product Series: Siemens SIMOVERT MASTERDRIVES
Component Type: Auxiliary Option Board / Interface Communication Adapter Module
Rated Operating Voltage: Internal power supplied directly via the MASTERDRIVES bus or control module ( $24 \text{ VDC}$ logic supply level)
Mounting Type: Plug-in module designed for direct slot mounting into MASTERDRIVES control electronics
Operating Ambient Temperature: $0\text{°C}$ to $55\text{°C}$
Storage Temperature: $-25\text{°C}$ to $70\text{°C}$
Degree of Protection: IP00 (open board structure, must be housed inside the drive chassis enclosure)
Weight: Approximately $0.2 \text{ kg}$

Product Advantages

A primary advantage of the 6SE7090-0XX84-0KA0 is its Direct System Integration. Being an original Siemens part designed specifically for the MASTERDRIVES platform, it guarantees full electrical and mechanical compatibility without the need for custom wiring or external signal converters.

Another advantage is its High Reliability and Noise Immunity. Designed for harsh industrial environments with heavy electromagnetic switching, the board utilizes industrial-grade circuit design to protect sensitive control logic from high-frequency noise generated by the drive power stage.

Additionally, its Compact Plug-in Design allows for quick installation and maintenance, minimizing drive downtime during upgrades or replacements.

Important Considerations and Precautions

When handling and installing the 6SE7090-0XX84-0KA0, electrostatic discharge (ESD) precautions are paramount. Since it is an open IP00 circuit board, handling it without proper grounding wrist straps can result in static damage to internal micro-components.

Power must be completely disconnected from the MASTERDRIVES unit before attempting to install, inspect, or remove the module. Wait at least 5 minutes after disconnecting the main power to allow the intermediate DC link capacitors inside the drive to discharge fully to a safe voltage level below $50 \text{ VDC}$ .

Ensure that the board is firmly seated in its designated slot and secured with its retaining screws to prevent intermittent signal contact caused by machine vibration.

Because the SIMOVERT MASTERDRIVES series is a legacy platform, ensure that your main control unit firmware is fully compatible with this specific hardware revision before commissioning.

Product Applications

The Siemens 6SE7090-0XX84-0KA0 is used wherever SIMOVERT MASTERDRIVES systems are deployed across heavy industrial automation sectors.

Metallurgy and Steel Mills: Integrated into main drive systems controlling rolling mills, continuous casters, and wire draw lines.
Paper and Printing Industry: Used in multi-motor synchronized drives for paper machines, winders, and heavy printing presses.
Crane and Hoist Systems: Applied in port container cranes and industrial overhead cranes requiring precise speed and torque control.
Chemical and Process Plants: Utilized in large-scale pump, fan, and mixer drive applications requiring networked control integration.
Test Benches: Employed in high-performance automotive and industrial test rigs where rapid drive response and communication are required.
