        Features:

        • Evaluates Speed Signals and External Trip Commands with Extreme Precision
        • Implements 2oo3 Voting Logic for Optimal Safety and Availability Balance
        • Integrates RS-232 Interface with Robust Relay Outputs for System Connectivity
        The BRAUN E1667.011 operates as the core Protection Monitoring Module within the E16 Protection System, providing critical supervision for rotating machinery in industrial environments. It continuously processes incoming speed signals and external trip commands to ensure turbines and large motors remain within safe operational limits. Certified to SIL3 safety integrity level, the BRAUN E1667.011 delivers reliable fail-safe protection against catastrophic mechanical failure caused by uncontrolled acceleration. The module's advanced 2oo3 (two-out-of-three) voting logic architecture ensures that genuine overspeed events trigger immediate protective action while preventing costly nuisance trips from single-sensor malfunctions.

        The BRAUN E1667.011 provides essential protection functions critical to the entire safety loop, serving as a vital component of the monitoring path that directly affects proper operation of the overall protection system. One BRAUN E1667.011 unit is required per protection point, occupying a dedicated slot within the control cabinet and typically positioned near turbine control rooms or heavy machinery for optimal signal integrity. The compact design allows for flexible installation while maintaining full operational capability across a wide temperature range.

        For applications requiring the highest reliability, the BRAUN E1667.011 employs its sophisticated 2oo3 voting mechanism to execute fail-safe decisions using internal circuitry that continuously monitors the health of three independent speed sensors. If the BRAUN E1667.011 detects a genuine overspeed condition—where a sudden loss of load could cause dangerous rotational speeds in milliseconds—it will automatically initiate a definitive trip command and log the event. Conversely, if only one sensor indicates a fault while the other two remain stable, the system identifies this as a sensor malfunction and maintains operation, thereby eliminating economically devastating unnecessary shutdowns in continuous-process industries.

        The E1667.011 BRAUN Protection Monitoring Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

        General

        • Manufacturer BRAUN
        • Model E1667.011
        • Condition New Original ready stock
        • Product Family E1655.51,E1667.x02,E1667.x03
        Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
        • Steam & Gas Turbine Protection: In power plants, the BRAUN E1667.011 monitors the RPM of turbines. If a generator suddenly disconnects from the grid (load rejection), the turbine can accelerate to destructive speeds in less than a second. This module detects the rise and triggers an emergency shut-off (Trip) within 15ms.
        • Petrochemical Compressors: Used in large-scale centrifugal compressors where consistent speed is vital for process pressure. The BRAUN E1667.011 ensures that mechanical limits are never exceeded, protecting the compressor seals and blades.
        • Emergency Feed Pumps: In nuclear or thermal power stations, the BRAUN E1667.011 monitors critical backup pumps to ensure they start and operate within safe parameters during a system failure.
        • Test Stand Safety: High-speed automotive or aerospace test benches use the BRAUN E1667.011 as an independent safety layer to protect personnel and expensive prototypes during stress testing.
        • SIL3 (Safety Integrity Level 3): Certified according to IEC 61508. This is the highest level of safety for a single electronic component in industrial applications, signifying a very low probability of failure on demand.
        • PL e / Cat. 3: Complies with DIN EN ISO 13849-1, indicating it meets "Performance Level e" requirements for machinery safety, typically required for high-risk equipment.
        • API 670 Compliant: Designed to meet the American Petroleum Institute’s standard for Machinery Protection Systems, which is the industry benchmark for oil, gas, and chemical sectors.
        • CE & EMC: Fully compliant with European electromagnetic compatibility standards to ensure the module does not fail due to radio interference or electrical noise in heavy industrial environments.
        • Sensor Interoperability: It is primarily compatible with Braun A5S Series differential Hall-effect sensors (e.g., A5S05, A5S09). These sensors provide the high-resolution frequency signal the BRAUN E1667.011 needs for ultra-fast response.
        • System Integration: It is the core unit of the Braun E16 Protection System (specifically the E16x342 and E16x346 series). It communicates with the E1691/E1697 Test Interface to allow "Hot Swapping" and online testing without stopping the turbine.
        • Control System Logic: The module provides redundant SPDT relay outputs that interface directly with Emergency Trip Manifolds (ETM) or DCS (Distributed Control Systems) like Siemens PCS7, Honeywell Experion, or Emerson DeltaV.
        • Configuration Software: Parameters are set via the AL_PRO software through its RS-232 interface, allowing for precise adjustment of trip levels, hysteresis, and signal filtering.
        Description
        The BRAUN E1667.011 is a Protection Monitoring Module engineered by Braun GmbH for the critical supervision of rotating machinery. As a core component of the E16 Protection System, the BRAUN E1667.011 is specifically designed to handle the complex challenges of overspeed protection in industrial environments. This BRAUN E1667.011 unit functions by evaluating speed signals and external trip commands with extreme precision, ensuring that turbines and large motors remain within safe operational limits. By providing a SIL3-certified safety integrity level, the BRAUN E1667.011 solves the problem of potential catastrophic mechanical failure due to uncontrolled acceleration, offering a reliable fail-safe mechanism for high-value assets.

        In practical application, the BRAUN E1667.011 is specialized for managing the demanding safety requirements of steam and gas turbines in power plants and petrochemical facilities. This BRAUN E1667.011 is designed for the specific scenario where a sudden loss of load could cause a turbine to reach dangerous rotational speeds in milliseconds. By utilizing its 2oo3 (two-out-of-three) voting logic architecture, the BRAUN E1667.011 solves the conflict between high safety and high availability; it prevents unnecessary shutdowns caused by single-sensor malfunctions while ensuring a definitive trip occurs if a genuine overspeed event is detected. The BRAUN E1667.011 effectively eliminates the risk of "nuisance trips", which can be economically devastating in continuous-process industries.

        Furthermore, the BRAUN E1667.011 addresses the need for long-term operational stability and simplified maintenance in harsh industrial settings.  The BRAUN E1667.011 solves the problem of frequent equipment testing by offering a 20-year maintenance-free useful lifetime, significantly reducing the total cost of ownership. With its integrated RS-232 interface and robust relay outputs, the BRAUN E1667.011 provides a seamless integration path for modernizing legacy protection systems or equipping new, high-speed industrial drive strings.
