Product Details

Baumuller 3.0309E1.0 is a revision E1.0 dedicated temperature monitor board and thermal detection PCB designed for legacy Baumuller modular servo drive assemblies. This temperature monitor board receives resistance signals from motor and power module thermal sensors, converts raw thermal readings into digital data, and transmits temperature status and alarm signals to the main control board. The thermal detection PCB provides over-temperature pre-warning and hardware shutdown triggering to protect motors, IGBTs and power components from thermal burnout. It adopts precision signal conditioning circuits and stable threshold logic for long-term reliable thermal supervision. The multi-layer FR4 circuit board is treated with conformal coating to defend sensitive traces against dust, moisture and corrosive vapors inside industrial control cabinets. As an obsolete and hard-to-source discontinued spare, it works as a matched drop-in replacement to restore full thermal monitoring protection for ageing Baumuller servo drives.

Supported Functions

This temperature monitor board supports continuous real-time thermal tracking for servo power components and servo motors. The thermal detection PCB samples signals from PTC and KTY thermal sensors, compares measured temperature against preset thresholds, and sends warning or fault signals once overheating occurs. It cooperates closely with the main control board, gate drive board and current sampling board to implement staged protection: first soft warning, then controlled drive shutdown to avoid catastrophic thermal damage. If this thermal sensing card fails, the system will lose temperature protection and cannot detect abnormal heat buildup inside the drive or motor.

Core Functions

The core function of this temperature monitor board is reliable thermal sensing and over-temperature protection for the servo drive system. It converts weak thermal sensor signals into usable temperature data for drive control logic. It provides independent hardware thermal interlock to stop unsafe operation when critical temperatures are exceeded. This thermal detection PCB serves as an essential spare to rebuild the thermal protection loop of legacy motion machinery and extend the service life of expensive servo power parts.
