Q61P MELSEC-Q Power Supply Module 100-240V AC 6A 5V DC | Mitsubishi

The Original New Mitsubishi Q61P is a power supply module for the MELSEC-Q series PLC system, designed to convert 100‑240V AC input into stable 5V DC power for the CPU, I/O modules, and other components mounted on the base unit. With a rated output current of 6A at 5V DC, it delivers reliable power distribution for medium to large Q series automation configurations. The module features built‑in overcurrent and overvoltage protection, an ERR contact output for external failure monitoring, and status LED indication. Designed for installation in the power supply slot of Q series base units, it ensures stable system operation in industrial automation, manufacturing, and process control applications.
