The TMEIC ARND-3119 A6 2N3A3119-B is an industrial control board associated with TMEIC inverter and motor-drive equipment. Available references identify ARND-3119 / 2N3A3119-B as a control board used within TMEIC drive and motor-control architectures.
TMEIC’s product portfolio includes high-power AC/DC motor-drive systems and inverter equipment used across industrial applications. The company describes its motor-drive products as variable-speed drive equipment for industrial motors, including high-voltage and large-capacity applications.
🔧 Main Function
The ARND-3119 A6 functions as a control/interface PCB within the inverter system. It is associated with control-signal processing, system logic, and coordination of inverter operation. It should be regarded as a drive-system control board, rather than a standalone PLC CPU.
The exact function and compatible inverter model depend on the surrounding TMEIC hardware configuration. The A6 revision and 2N3A3119-B identification should be matched when sourcing a replacement.
