The Omron CP1H-XA40DT-D is a compact, scan-based PLC from the CP1 series, built around a 24 VDC supply with 24 digital inputs and 16 transistor (sinking) outputs. Scan time runs 700 µs — fast enough for most discrete and analog control loops in a single machine or small line. Onboard memory is 32K words for data and 20K steps for program storage. The LED 7-segment display shows status and diagnostic codes without a connected HMI. Expansion via additional I/O modules is supported, with a maximum of 320 I/O points across the rack. The Real-Time Clock and battery backup keep time and data through power loss. Communication is via USB for programming. The screw terminal block is used for wiring. The transistor outputs are rated 300 mA per point; total load current is the same 300 mA — meaning you cannot sink more than 300 mA across any combination of outputs simultaneously. That is the package limit, not per-channel. Watch for inrush on inductive loads like small DC solenoids.

Frequently asked questions
What is the series of CP1H-XA40DT-D?
It belongs to the CP1 series.
What is the scan time of CP1H-XA40DT-D?
The scan time is 700 µs.
Will CP1H-XA40DT-D drop into a panel wired for CP1H-XA40DR-A?
Not without rewiring the output field. The -DT uses sinking transistor outputs (300 mA) while the -DR uses relay outputs (2 A, voltage-free). The CPU housing, backplane, and expansion are identical, but output wiring is electrically different.
