A1SJ71PB96F

The A1SJ71PB96F is a PROFIBUS-DP (Decentralized Periphery) slave module for Mitsubishi's MELSEC-A Series PLCs, enabling seamless integration with PROFIBUS-DP networks (up to 12Mbps). It allows A-Series PLCs to communicate with PROFIBUS-compatible devices (sensors, drives, HMIs) in industrial automation systems.
