CC-Link master/local node for MELSEC Q racks
The QJ61BT11N is a CC-Link master/local module for Mitsubishi Electric's MELSEC Q series PLCs, handling both master and local station roles on a bus (RS-485) network. Transmission speed is field-selectable from 156 kbps up to 10 Mbps, letting the integrator match the baud rate to cable length and noise environment without swapping hardware. Up to 64 stations can be connected on one link, and the module occupies 1 to 4 stations depending on the remote station count needed — useful for scaling a line without swapping the master. It draws 0.46 A from the 5 VDC backplane — a standard load for a Q-series slot, so no special power-supply derating is needed for a single module.
