The Q64RD: Four analog inputs, each configurable for Pt100 or JPt100 (JIS C 1604-1989 / DIN IEC 751). Resolution hits 0.025°C per step — fine enough for process monitoring, not lab-grade but solid for industrial sensor chains. Conversion runs at 40 ms per channel, which keeps the scan in sync with a Melsec Q CPU's slow-cycle tasks. Removable 18-screw terminal block means the field wiring stays put when the module comes out for swap.
Marked as mature lifecycle — still stocked through distribution and quoted to order, but no longer a focus for new development. For a line-down replacement on a Melsec Q-series rack, this is the correct part. No need to re-engineer the panel. Lead times are short; we quote firm against your BOM line.
