BAUER SIRAX TV808 808-611100 Ruggedized DC Drive Control Module

Product Overview

BAUER SIRAX TV808 808-611100: Industrial-Grade DC Drive Control for Harsh Environments

The BAUER SIRAX TV808 (Part No. 808-611100) is a ruggedized plug-in DC drive control module engineered for continuous, fault-tolerant operation in the most demanding industrial environments. Built on BAUER’s proven SIRAX drive platform, this module delivers precise armature current regulation, speed feedback processing, and field excitation control — all within a compact plug-in form factor designed for direct integration into SIRAX series DC drive cabinets.

Whether deployed in steel rolling mills, underground mining conveyors, offshore pump stations, or high-cycle paper machine drives, the SIRAX TV808 maintains stable closed-loop DC motor control under conditions that would compromise lesser components: ambient temperatures up to 55 °C, high relative humidity, airborne conductive dust, continuous mechanical vibration, and intense electromagnetic interference from adjacent variable-frequency drives, large contactors, and high-current bus bars. Its robust PCB conformal coating and shielded signal paths ensure that analog speed references and tachometer feedback signals remain clean and accurate even in electrically noisy switchgear rooms.

In critical infrastructure applications, the TV808 functions as the intelligence layer between the operator’s PLC or DCS command signals and the power stage of the DC drive. It accepts setpoint references from Siemens S7-300/S7-400 PLCs, ABB AC500 controllers, or Schneider Electric Modicon M340 systems via hardwired analog interfaces, and it coordinates with upstream safety relay modules and emergency-stop circuits to ensure safe, controlled deceleration on loss of command signal. The module’s internal diagnostics continuously monitor armature current limits, field weakening thresholds, and thermal status, feeding fault codes back to the host control system for predictive maintenance integration.

Comprehensive Protection Solutions

The SIRAX TV808 808-611100 is rarely deployed in isolation. In a fully engineered DC drive system, it works in concert with a suite of complementary components to deliver layered protection and reliable motor control. Within the BAUER SIRAX drive chassis, the TV808 control card interfaces directly with the SIRAX power thyristor bridge and the SIRAX field supply unit, forming a tightly integrated three-element DC drive stack. Upstream, a BAUER SIRAX TF-series field controller or a dedicated field weakening module manages the motor’s excitation winding, extending the speed range while protecting the armature from over-flux conditions.

On the protection side, the TV808 coordinates with DIN-rail mounted motor protection relays and thermal overload relays installed in the same control cabinet, ensuring that armature overcurrent events trigger a controlled shutdown rather than a hard trip. In plants where functional safety is mandated — such as SIL 2 or SIL 3 classified zones in oil refineries or chemical processing facilities — the TV808 integrates with Pilz PNOZ safety relay modules or Siemens SIRIUS 3SK safety relays to enforce safe-state logic on emergency stop commands.

Communication between the drive system and the plant DCS is typically handled through a dedicated communications module or a hardwired analog I/O terminal block assembly. In many SIRAX installations, Phoenix Contact TRIO-series 24 VDC industrial power supplies provide the stable auxiliary voltage rail that powers the TV808 control electronics, while Weidmüller or Phoenix Contact terminal blocks distribute signals cleanly across the cabinet. Surge protection devices on analog input terminals — such as those from Dehn or Phoenix Contact — guard the TV808’s sensitive signal conditioning circuits against transient overvoltages induced by nearby high-power switching equipment.

For facilities running mixed drive architectures, the TV808 can coexist in the same MCC lineup as ABB DCS800 or Siemens SIMOREG DC Master drives, with the plant PLC acting as the supervisory coordinator. This interoperability makes the BAUER SIRAX TV808 a practical choice for brownfield upgrades where legacy DC motor infrastructure must be preserved while modern control and safety layers are added.

Application in Critical Infrastructure

In steel and metals processing, the SIRAX TV808 controls the main drive of rolling mill stands, coiler drives, and tension reels — applications where precise torque and speed regulation directly determine product quality and line throughput. The module’s fast current loop response ensures that strip tension remains constant through acceleration and deceleration transients, preventing cobbles and surface defects.

In underground mining, the TV808 powers hoist drives, conveyor belt drives, and ventilation fan motors in environments characterized by coal dust, high humidity, and continuous vibration. Its conformal-coated PCB resists the conductive particulate contamination that causes premature failure in unprotected control electronics. Replacement of a failed control module with a pre-tested SIRAX TV808 from stock can restore a hoist drive to service in hours rather than the days required to source an unverified component.

In oil and gas upstream and midstream facilities, the TV808 drives pump motors and compressor auxiliaries in classified hazardous areas, where the drive cabinet is located in a safe zone but must respond reliably to commands from a remote DCS in the control room. The module’s stable analog interface and robust fault reporting support the high-availability requirements of continuous production processes where unplanned downtime carries significant financial and safety consequences.

In water and wastewater treatment, SIRAX TV808-equipped drives control large DC pump motors in raw water intake stations and effluent pumping stations, where the combination of high ambient humidity, chemical vapors, and 24/7 duty cycles demands components with proven long-term reliability. Municipal utilities and industrial water treatment operators value the availability of genuine spare modules with documented provenance and warranty coverage as part of their asset management programs.

In power generation and grid support applications, the TV808 has been deployed in excitation control systems for synchronous generators and in DC motor drives for auxiliary equipment such as coal feeders, ID/FD fans, and cooling water pumps at thermal power stations. The module’s ability to maintain stable field and armature control under fluctuating supply conditions makes it well suited to the demanding electrical environment of a power plant switchgear room.

Security & Quality FAQ

Q1: What does the 12-month warranty cover, and how is a claim processed?
The 12-month warranty covers all manufacturing defects and functional failures under normal operating conditions from the date of shipment. If a module fails within the warranty period, contact us at [email protected] with the order reference and a description of the fault. We will arrange return shipping, perform a technical inspection, and provide a replacement or repair at no additional cost. Warranty does not cover damage caused by incorrect installation, overvoltage events beyond rated limits, or unauthorized modification.

Q2: How is each BAUER SIRAX TV808 808-611100 tested before shipment?
Every unit undergoes a pre-shipment functional inspection that includes visual examination of the PCB and connectors, power-on verification of control circuitry, and confirmation of key electrical parameters. Units that do not pass inspection are quarantined and not offered for sale. A test report is available upon request for customers with documented quality assurance requirements.

Q3: Is the SIRAX TV808 808-611100 compatible with all BAUER SIRAX drive chassis variants?
The TV808 is designed for the BAUER SIRAX series DC drive platform. Compatibility depends on the specific chassis generation and firmware revision of the host drive. We recommend confirming the host drive model and serial number before ordering. Our technical team can assist with compatibility verification — contact [email protected] or call +86 18359293191 with your drive nameplate data.

Q4: Can you support long-term or repeat supply of this module for ongoing maintenance programs?
Yes. We maintain stock of BAUER SIRAX modules to support planned maintenance, emergency replacement, and multi-site spare parts programs. For customers with recurring demand, we can discuss reserved stock arrangements and priority dispatch agreements to ensure that critical spare parts are available when needed, minimizing the risk of extended production downtime.
