Specification

SEODescription

The Mitsubishi Q61LD module is a versatile analog input module designed for precise temperature monitoring in industrial applications. It features 4 isolated channels for Q61LD analog input, supporting various temperature sensors including thermocouples and RTDs (Q61LD temperature sensor compatibility). Directly connectable to Mitsubishi PLC systems via the MELSEC communication interface, it operates within a 24 VDC power range and withstands industrial environments with a working temperature range of 0°C to 55°C. Widely used in process control, manufacturing, and HVAC systems, the Q61LD module offers high-resolution measurement (16-bit) and channel-to-channel isolation for reliable data acquisition. Key advantages include easy configuration via GX Works software and robust noise resistance, though its specialized temperature focus limits versatility for other analog signal types. This module requires regular calibration to maintain measurement accuracy in critical applications.
