CPU description and I/O count
The Omron CP1H-XA40DT1-D is a CP1H-series PLC CPU running on 24 VDC, with a 32K-word program memory and a mix of 24 inputs (20 digital, 4 configurable as analog/digital) and 16 outputs (2 analog, 4 pulse, 10 solid state). Communications include USB and option card slots for fieldbus or serial expansion. The unit mounts on DIN rail or chassis, with a two-character red LED display for diagnostics. The battery backup retains program data during power loss.
Sibling comparison: CP1H-X40DT-D
The nearest sibling in the series, CP1H-X40DT-D, provides 24 digital-only inputs and 16 outputs (4 pulse, 12 solid state). The XA40DT1-D trades two of those solid-state outputs for two analog outputs and four of the digital inputs for four analog/digital combo inputs. The analog channels occupy different I/O terminals, so a panel wired for the X40DT-D requires rewiring for the XA40DT1-D.
