QJ61BT11N CC-Link Master/Local Module Ver.2 10Mbps | Mitsubishi

The Original New Mitsubishi QJ61BT11N is a CC-Link master/local module for the MELSEC-Q series PLC system, designed to provide high-speed, deterministic fieldbus communication for industrial automation applications. Supporting both CC-Link Ver. 1 and Ver. 2, this module can operate as either a master station or a local station, offering flexible network configuration. It enables high-speed transmission of bit data (ON/OFF status) and word data (analog values) up to 10 Mbps, with a maximum of 8,192 remote I/O points and 2,048 remote register points per system in Ver. 2 mode. The module features broadcast polling communication, RS-485 bus transmission, and independent cyclic and transient transmission paths, ensuring link scan time is not affected by message communication. With a 0.46 A current consumption and compact 98 × 27.4 × 90 mm dimensions, it is suitable for factory automation, process control, and distributed I/O applications.
