Product Description
This module provides eight analog input channels for MELSEC-A series local I/O, supporting ±10 VDC, 0–10 VDC, and 4–20 mA signal types. It is designed as an analog-to-digital conversion unit for PLC systems requiring reliable acquisition of process variables. The unit offers a 1/2000 conversion resolution, suitable for general monitoring and control tasks across industrial applications. Use it within Mitsubishi Electric MELSEC-A architectures to expand analog input capacity on local racks. The module interfaces through a terminal block for field wiring and is intended for integration by control engineers familiar with PLC I/O configuration, scaling, and channel assignment. Suitable for discontinued legacy systems, ensure compatibility with existing backplanes and power budgets before deployment. Package contents typically include the module only; consult system documentation for wiring accessories and installation details.
