Product Description
The A1SJ61QBT11 is a CC-Link communication module for Mitsubishi MELSEC‑A QnAS PLC systems, providing high-capacity remote I/O and register access over a robust RS‑485 bus architecture. Designed for backplane/rack installation within QnAS CPUs, it supports up to 2048 I/O points and configurable occupied stations for flexible network topologies. Transmission speeds are selectable from 156 kbps up to 10 Mbps, using NRZI encoding and broadcast polling for deterministic control traffic across CC‑Link networks. The module consumes 0.4 A at 5 VDC and operates from 0°C to 55°C, making it suitable for typical industrial environments. It occupies 32 special I/O points and offers 256-point remote registers in each direction between master and local/remote stations. This unit is ideal for expanding distributed control, enabling seamless integration of multiple remote devices and modules while maintaining reliable communication performance within MELSEC‑A series automation architectures.
