Product Overview
The Omron CP1H-X40DR-A is a high-performance compact PLC from the CP1H family, with 40 built-in I/O points wired through a removable terminal block. The split is 24 DC inputs and 16 relay outputs, on an AC 100-240 V supply. It sits in the middle of the CP1H lineup: powerful enough for packaging machines, small assembly cells, or building services, compact enough to mount in a tight cabinet. The 20K-step program and 32K-word data memory match several larger CP1H variants, so engineers can standardize one platform across smaller and bigger machines.
What the X gives you over L or M
CP1L is the entry-level compact PLC and CP1M is the mid-range. CP1H-X is the high-performance sibling, and the jump shows up in three places: 0.1 µs basic instruction time, four high-speed counter channels (phase differential at 50 kHz, single-phase at 100 kHz), and four pulse outputs (two at 100 kHz, two at 30 kHz) for stepper or simple servo axis control. Need 1 MHz pulse output for a fast positioning axis? Move up to CP1H-Y. Need two analog inputs and one analog output built in? Move to CP1H-XA. For most OEM machine sequencing on relay loads, X is the right pick.
Why AC power and relay outputs
The "DR" in the suffix means relay outputs; the matching "DT" is NPN transistor sinking for high-cycle solenoid or stepper pulse wiring, and "DT1" is PNP sourcing. The trailing "A" means AC 100-240 V supply; "D" is 24 VDC supply for cabinet builders who already run a 24 V bus. Pick this "DR-A" SKU when you need to switch mixed-contact loads such as motor contactors, solenoid valves on 110/220 VAC, indicators, and small heaters from one terminal block, and when the cabinet feeds straight off AC mains without an intermediate 24 VDC supply.
Before ordering
Confirm the load on each relay point. Common ratings are 2 A at 250 VAC / 24 VDC for resistive loads, dropping well below that on inductive or motor loads. Plan for up to 7 CP1W expansion units and 320 total I/O if the panel will grow. Use CX-Programmer over the built-in USB port, and add an RS-232C or RS-422/485 option board (CP1W-CIF01 / CIF11 / CIF12) for Modbus-RTU, host link, or serial PLC link.

Buying Checklist
- Pick CP1H-XA40DR-A instead if you also need 2 analog inputs + 1 analog output built in (no extra expansion module).
- Pick CP1H-X40DT-D instead if you run 24 VDC cabinets and want NPN transistor sinking outputs.
- Pick CP1H-Y for 1 MHz pulse-output positioning; the X is 30 kHz max for fast axes.
- Add a CP1W-CIF01 option board for RS-232C, CP1W-CIF11 for RS-422/485.
- Confirm relay point ratings for inductive loads (motor contactors, solenoids) — derate from the 2 A resistive figure.

FAQ for CP1H-X40DR-A
What is the difference between CP1H-X40DR-A and CP1H-XA40DR-A?
The XA variant adds built-in analog I/O: 4 analog inputs (0-10 V or 4-20 mA selectable) and 2 analog outputs, plus raises pulse outputs to 1 MHz. Pick XA when you need to read a temperature or pressure transmitter and drive a variable-speed drive without buying extra expansion modules. Pick the plain X when the panel only does digital sequencing and you would rather add a CP1W-AD041 analog card for a couple of channels.
Can CP1H-X40DR-A connect to a CP1W expansion unit and CJ-series I/O rack?
Yes to CP1W expansion (up to 7 units including analog, communication, and I/O modules). No to CJ-series rack-mounted I/O: the CP1H is a compact PLC family that uses CP1W units only. For CJ-series I/O you need a CJ1M, CJ2M, or CJ2H CPU on a CJ1W power supply.
How do I program the CP1H-X40DR-A?
Over the built-in USB port using CX-Programmer (CX-One suite). Ladder, structured text, and function blocks are supported, and CP1H projects can re-use function blocks previously written for CJ1 / CS1 / NJ controllers, so multi-platform OEMs keep one library.
