Siemens 6SL3350-6TK00-0BA0 Ruggedized Active Line Module for Harsh Environments

Product Overview

Siemens 6SL3350-6TK00-0BA0 Ruggedized Active Line Module for Harsh Environments

The Siemens 6SL3350-6TK00-0BA0 is a 16 kW Active Line Module (ALM) within the SINAMICS S120 Booksize drive system — engineered to deliver clean, regulated DC bus power to servo and vector drive axes in the most demanding industrial environments. Designed to operate continuously in high-temperature, high-humidity, dust-laden, and vibration-intensive facilities, this module is a cornerstone of reliable motion control and power management across heavy industry, process automation, and critical infrastructure.

Unlike passive infeed components, the 6SL3350-6TK00-0BA0 actively regulates the DC link voltage and enables regenerative energy feedback to the supply grid, dramatically reducing energy consumption in cyclic drive applications such as press lines, winding machines, and multi-axis machining centers. Its integrated active front-end topology ensures near-unity power factor and low harmonic distortion, protecting upstream transformers and switchgear from thermal stress caused by harmonic currents.

In environments where electromagnetic interference (EMI) is a persistent challenge — such as arc furnace facilities, high-frequency welding lines, or variable-speed pump stations — the 6SL3350-6TK00-0BA0 maintains stable DC bus regulation without compromising the signal integrity of co-located SIMATIC S7 PLCs, ET 200SP distributed I/O stations, or PROFINET communication networks. Its shielded Booksize form factor and compliance with CE/UL/cUL standards make it suitable for installation in IEC 61439-compliant control cabinets alongside Motor Modules, Sensor Modules, and Control Units such as the CU320-2 PN.

Comprehensive Protection Solutions

The 6SL3350-6TK00-0BA0 Active Line Module is rarely deployed in isolation. In a fully configured SINAMICS S120 Booksize drive line-up, it supplies regulated DC bus power to one or more Single Motor Modules (e.g., 6SL3120-1TE21-0AA3) or Double Motor Modules, each independently controlling servo axes or induction motors. The Control Unit CU320-2 PN orchestrates all drive objects over DRIVE-CLiQ, enabling centralized parameterization, diagnostics, and safety function management via SIMATIC STEP 7 or TIA Portal.

For installations requiring functional safety, the ALM integrates seamlessly with Safety Integrated functions available on compatible Motor Modules, supporting STO (Safe Torque Off), SS1 (Safe Stop 1), and SLS (Safely Limited Speed) without the need for external safety relays. In control cabinets where space is constrained, the Booksize format allows the 6SL3350-6TK00-0BA0 to be mounted directly adjacent to the Braking Module (6SL3100-1BE21-3AA0) and the SITOP PSU8600 24 V DC power supply, maintaining a compact and thermally efficient layout.

On the field bus side, the CU320-2 PN Control Unit connects to SIMATIC ET 200SP distributed I/O racks via PROFINET, enabling real-time process data exchange between the drive system and upstream SIMATIC S7-1500 PLCs. For legacy installations using PROFIBUS DP, the CU320-2 DP variant provides equivalent functionality. Terminal Modules such as the TM31 expand the analog and digital I/O capacity of the drive system, supporting encoder feedback, external fault signals, and process interlocks from field instruments.

In high-power applications, the 6SL3350-6TK00-0BA0 may be paralleled with additional Active Line Modules to scale infeed capacity, with the SINAMICS S120 system managing load sharing automatically. Line-side components including the SINAMICS S120 Line Filter (6SL3000-0BE21-6DA0) and Line Reactor (6SL3000-0CE21-6AA0) are recommended upstream to ensure EMC compliance and protect the module from supply-side transients in industrial grid environments.

Application in Critical Infrastructure

In oil and gas upstream facilities, the 6SL3350-6TK00-0BA0 powers variable-speed electric submersible pump (ESP) drives and compressor motor control systems where unplanned downtime translates directly to production loss and safety risk. Its regenerative capability allows energy recovery during pump deceleration cycles, reducing heat dissipation in enclosed equipment rooms and lowering overall facility energy costs.

In mining and mineral processing plants, the module operates reliably in environments characterized by heavy dust ingress, mechanical vibration from crushers and conveyors, and wide ambient temperature swings between day and night shifts. Installed within sealed, climate-controlled MCC (Motor Control Center) enclosures, the 6SL3350-6TK00-0BA0 drives conveyor belt motors, ball mill drives, and slurry pump systems with consistent torque response and fault-tolerant operation.

Power generation and water treatment facilities rely on the SINAMICS S120 platform — anchored by Active Line Modules like the 6SL3350-6TK00-0BA0 — to control boiler feed pumps, cooling water circulation systems, and aeration blowers. The module’s active harmonic compensation reduces total harmonic distortion (THD) on facility power networks, protecting sensitive metering equipment and preventing nuisance tripping of protection relays.

In steel and aluminum smelting operations, where electromagnetic interference from arc furnaces and induction heaters is extreme, the 6SL3350-6TK00-0BA0’s robust EMC design and shielded DRIVE-CLiQ cabling maintain communication integrity between the Control Unit and Motor Modules, ensuring continuous production without drive faults caused by conducted or radiated interference.

Security & Quality FAQ

Q1: What does the 12-month warranty cover for the 6SL3350-6TK00-0BA0?
The 12-month warranty covers all manufacturing defects and functional failures under normal operating conditions from the date of shipment. This includes internal component failure, firmware-related hardware faults, and DRIVE-CLiQ interface defects. Physical damage caused by incorrect installation, overvoltage events beyond rated tolerance, or unauthorized modification is excluded. Warranty claims are processed with full technical documentation and replacement or repair turnaround support.

Q2: How is each unit tested before shipment?
Every 6SL3350-6TK00-0BA0 unit undergoes pre-shipment functional verification including power-on self-test, DC link voltage regulation check, DRIVE-CLiQ communication handshake validation, and visual inspection for connector integrity and mechanical condition. Units sourced from original Siemens production channels are cross-referenced against serial number records where available. Test reports can be provided upon request for critical infrastructure procurement.

Q3: Is the 6SL3350-6TK00-0BA0 compatible with my existing SINAMICS S120 installation?
Yes. The 6SL3350-6TK00-0BA0 is fully compatible with the SINAMICS S120 Booksize drive system and integrates with CU320-2 PN and CU320-2 DP Control Units via DRIVE-CLiQ. It is backward compatible with existing S120 Motor Modules and Sensor Modules. Firmware version alignment with the Control Unit is recommended and can be managed via STARTER or TIA Portal Drive Configurator. Our technical team can advise on firmware compatibility for your specific system configuration.

Q4: Can you support long-term supply and emergency replacement requirements?
Yes. TOPNLMS maintains stock of SINAMICS S120 components including Active Line Modules, Motor Modules, and Control Units to support both planned maintenance schedules and emergency breakdown replacement. Orders are processed with same-day or next-business-day dispatch for in-stock items. For facilities requiring guaranteed spare parts availability, we offer reserved stock arrangements.
