Specification

SEODescription

The FX3U-8AV-BD is a Mitsubishi 8AV-BD module designed as an FX3U analog expansion board, adding 8 analog input channels to FX3U PLC systems for voltage/current signal acquisition (0-10V DC or 4-20mA). It connects directly to the FX3U main unit without occupying expansion slots, operating at 24V DC ±10% with a 12-bit resolution. Compatible with temperature ranges of 0-55°C, this compact module suits industrial automation, process control, and machinery applications requiring precise analog monitoring. Its key advantages include simplified wiring, space efficiency, and real-time analog data processing through the PLC's main CPU. However, it lacks isolated inputs and cannot be cascaded with other analog modules. The FX3U-8AV-BD excels in cost-effective analog expansion but requires external signal conditioning for high-noise environments.
