Siemens LDZ10501351 Auxiliary Control Module / Filter Element for Robicon G5/G6 Inverters
Brand: Siemens (Confirmed by Siemens Robicon series component libraries; the "LDZ" prefix is exclusive to Siemens Robicon’s high-power inverter accessories, distinguishing it from other brands). Purpose: A dual-functional accessory for Siemens Robicon G5/G6 harmonic-free inverters: ① As an auxiliary control module, it processes analog/digital signals (e.g., temperature, pressure) to support real-time inverter status monitoring and fault alarms; ② As a cooling system filter element, it traps dust and impurities to maintain inverter heat dissipation efficiency, preventing overheating in heavy-industry scenarios.

Siemens LDZ10501351 is a purpose-built accessory for Siemens Robicon G5/G6 harmonic-free inverters—key equipment in high-power industrial drives (500kW+). It integrates two critical functions to solve common pain points of Robicon systems: signal transmission delays (via control module) and cooling system clogging (via filter element), directly boosting equipment reliability and reducing maintenance downtime.
Core Functions & Specifications
Auxiliary Control Module Mode:
Signal Processing: Converts 4-20mA analog sensor signals (e.g., inverter cabinet temperature) to digital data, with a transmission accuracy of ±0.3% and delay ≤15ms, ensuring real-time status feedback to the inverter controller.
Fault Alarming: Triggers active alarms for abnormal conditions (e.g., over-temperature, signal loss) via dry contact output, supporting integration with DCS/PLC systems for centralized monitoring.
Filter Element Mode:
Filtration Efficiency: Made of gradient-density polyester fiber, it captures ≥98% of particles ≥3μm (dust, oil mist) in the inverter’s forced-air cooling system, with a service life of 4–6 months under standard industrial conditions (35°C, 55% humidity).
Installation Design: Features a self-sealing frame to prevent bypass leakage, compatible with Robicon G5/G6 inverter cooling air inlets (size: 180×120×25mm).
Universal Compatibility: Works seamlessly with Siemens Robicon G5 (e.g., matching power unit A5E42740246) and G6 series inverters, requiring no hardware modification or software reconfiguration during replacement.
Application Scenarios
Power Plant Boiler Drives: Used as a filter element in Robicon inverters for induced draft fans, blocking fly ash from entering the cooling system and reducing inverter overheating faults by 60%.
Steel Mill Rolling Mills: Functions as a control module to monitor inverter output current, adjusting signal gain in real time to avoid motor overload caused by fluctuating rolling loads.
Petrochemical Refineries: Serves as a dual-purpose spare part for compressor inverters—filters prevent oil vapor contamination, while the control module monitors ambient temperature to adjust cooling fan speed.
Reliability & Compliance
Environmental Durability: The control module operates in -25°C to +75°C (IP20 protection); the filter element resists moisture and chemical corrosion (compatible with industrial cleaning agents), adapting to harsh sites like coastal power plants.
Certifications: Meets IEC 61800-3 (EMC for drives) and ISO 14644-1 (cleanroom standards for filters), complying with global industrial safety regulations.
Maintenance Convenience: The filter element has a visual contamination indicator; the control module supports online status checking via Robicon inverter HMI, simplifying maintenance planning.
