The Q61LD is a MELSEC-Q Series analog unit from Mitsubishi Electric for load cell input. It converts load cell signals into weight values for the PLC, supporting weighing, filling and batching applications. Typical applications include hopper scales, filling machines, batching systems and checkweighers that need weight values directly in the PLC.
