Product Description
The A1SJ61BT11 is a CC-Link communications module for Mitsubishi Electric’s MELSEC-A AnS series PLC platforms, designed to provide deterministic field network connectivity over a backplane-mounted architecture. It supports operation as either a CC-Link master station or local station, enabling flexible topologies in distributed control. Transmission speeds are selectable from 156 kbps to 10 Mbps and utilize an RS‑485 bus with HDLC framing and NRZI encoding for robust, noise-immune data exchange. The module integrates broadcast polling and frame synchronous methods to maintain cyclic I/O data updates and supports up to 64 connected modules when configured as a master. Connection capacity is specified at 2048 I/O points, aligning with large A-series installations. It is technically compatible with AnS CPUs and uses CC‑Link dedicated cabling. Typical use cases include factory automation cells where fast, deterministic device-level communication is required across drives, I/O slices, and intelligent stations. The unit draws 0.4 A at 5 VDC from the PLC backplane and installs directly in the rack for streamlined integration without external gateways.
