The LUETZE LOCC-Box is an intelligent electronic overload and short circuit monitoring system designed for Industry 4.0 applications. It enables selective shutdown even with high cable impedance, integrating seamlessly into existing communication networks. Optimized for switching capacitive loads, it stores error data to prevent repeated disturbances upon restart. Available in 1- and 2-channel versions within an ultra-compact 8.1 mm module, the LUETZE LOCC-Box offers up to 50 configurable settings and uses bridges instead of wiring for quick connection.

The LUETZE LCOS CC (I) system is an advanced electronic overload and short-circuit protection solution, building upon the proven functions of the LOCC-Box. It features selective shutdown, high line attenuation, and integrated fault memory. Available in 2-channel and 2-pole modules, it includes a powerbus for the return circuit, allowing direct load connection. Diagnostics can be performed via LOCC-Pads or fieldbus integration for enhanced monitoring and control.

LUETZE LCIS series relays, solid-state relays, and isolating converters support isolation voltages up to 4 kV, offering reliable switching and coupling for a wide range of applications. Designed for operating temperatures from -40 °C to 75 °C, they handle loads up to 250 V/16 A. Available with screw, tension spring, and push-in connections, LCIS relays carry UL, CSA, and GL approvals for global use. The innovative LCIS housing enables simplified installation via isolated bridges and various termination options. With a compact depth of just 71 mm, they fit easily into low-profile distribution boxes, and marking tabs allow easy, error-reducing labeling.

LUETZE LCIS series converters are designed for a wide range of industrial applications, performing tasks such as signal conversion, temperature measurement, and signal boosting or isolation. With extremely low heat dissipation and minimal power loss, these units are suitable for demanding environments, including hard-to-reach and remote locations like wind turbines. Operating within a temperature range of -40 °C to +75 °C, they combine robust performance with a compact 71 mm depth, allowing installation in distribution boxes. Marking tabs simplify labeling, reduce wiring errors, and streamline installation.

The LUETZE LCOS Power Supplies is an ultra-compact 120 W switching power supply unit designed within the successful LCOS housing system. As one of the smallest 120 W power supplies worldwide, it offers enhanced over-voltage protection, integrated Power Factor Correction (PFC), and a fault message output for improved safety and performance. Ideal for space-constrained applications, the LCOS PS delivers reliable power in a highly compact form factor.

The LUETZE relay module with positive-action contacts complies with IEC 61810-3, IEC/EN 60255, and IEC 60664-1 standards, making it suitable for safety-related applications in rail technology. Depending on requirements, the module can be supplied with 2 (1NO/1NC) up to 8 contact sets (7NO/1NC). With positively driven contacts, it ensures maximum safety and reliability. Clearances and creepage distances of ≥ 5.5 mm provide enhanced insulation. Relay modules are available for all operating voltages commonly used in rail applications.

The LUETZE function (timing) relay is a versatile and freely programmable solution, configurable via free software. A pre-configured model tailored to customer specifications is also available ex works. With wide-range voltage supply and control, it supports all standard on-board voltages from 24 V to 110 V DC. Available with semiconductor outputs for 24 V and 110 V or with positively driven contacts, the LUETZE timing relay ensures flexibility and safety in railway applications.

The LUETZE Audio Signal Transducer with TRDP enables flexible audio playback and control for rail applications. Configuration (IP and audio) is managed via a web server, while playback is controlled by TRDP message data telegrams or digital inputs. Supporting up to 256 audio files (approx. 15 MB), it allows easy copy and paste of configurations through a web interface. Integrated volume control offers predefined presets, default (100%), or configurable/TRDP-controlled volume settings.

The LUETZE Audio Signal Transducer provides playback of acoustic warnings, speech, and melodies for railway applications. It supports a total audio length of up to 15 minutes, controlled via 6 digital wide-range inputs. Audio files can be prioritized, and volume is adjustable using the integrated potentiometer. Compatible with *.WAV and *.MP3 formats, it is available in versions for wall mounting or with an external speaker. The unit is programmable via free software, making it versatile for customized audio signaling in demanding environments.

The LUETZE Universal Buzzer is designed for versatile acoustic signaling across a wide range of applications. Different tones can be parameterized via the programming interface, either directly from LUETZE or through free software. Operating with voltages between DC 24 V and 110 V, it supports multiple operating modes including continuous, interval, or change-over. Available in three versions – wall mounting, back wall mounting, or DIN rail mounting – the Universal Buzzer provides maximum flexibility for integration in rail and industrial environments.

The LUETZE External Audio Signal Transducer is a powerful electronic sound generator designed for outdoor warning applications. Delivering sound pressure levels of up to 122 dB(A) at 1 m (depending on tone and settings), it ensures clear signaling in demanding environments. Controlled via 4 digital inputs (binary codable) with up to 14 tones available, it offers versatile signaling options. Multiple connection variants are available, including round plug, plug housing, and 90° C angle plug. Day and night control input allows reduction of sound pressure levels at night. Easy programming is possible via a configuration tool with multiple setting options.
