CP1H-X40DT-D

Product information

Product Overview

The CP1H-X40DT-D is Omron’s CP1H compact PLC with 24 DC inputs and 16 transistor (NPN) outputs — 40 built-in I/O points — running on 24 V DC supply with 20 K steps of program capacity and 4 built-in high-speed counter / pulse-output axes.

This page is written for buyers and maintenance engineers sourcing CP1H-X40DT-D as a new part or a replacement. Every specification below is taken from Omron’s own published catalogue data for this model; no third-party or estimated figures are used, and where Omron publishes two different figures for the same parameter, both are shown.

Omron catalogue position: Automation Systems › Programmable Logic Controllers (PLC) › CP1H. Official catalogue code for this model: CP1H-X40DT-D.

Why Buyers Specify This Model

40 built-in I/O, no expansion needed for a small machine

24 inputs and 16 NPN transistor outputs are on the CPU itself, so a compact machine can be built with a single unit. The range extends to 7 expansion units and a maximum of 320 local I/O points when you outgrow it.

Built-in motion: 4 encoder channels and 4 pulse axes

Omron’s data gives 4 encoder input channels and 4 PTP axes at 100 kHz maximum pulse output, with 100 kHz maximum encoder input frequency. Positioning is handled by the CPU without a separate motion module.

20 K steps, 32 K words, 0.10 µs

Program capacity is 20 K steps with 32 K words of data memory and a 0.10 µs LD instruction execution time. Function Block programming is supported, and a real-time clock is built in.

Up to 56 analog channels via option boards

Omron’s specification allows a maximum of 56 analog I/O channels through CP1W analog option boards — analog is added as boards rather than taking rack space.

Lifecycle & Availability

Omron’s official product data for this model carries no end-of-production or discontinuation notice — it is listed as a current catalogue item. That is the lifecycle status as published by Omron, not a stock statement on our side.

Availability, condition of supply and lead time are quoted per enquiry because they depend on quantity and on where the goods are held. Tell us the quantity and the date you need it and we will answer with a firm position rather than a promise.

Matching Accessories and Spare Parts

The list below is Omron’s own accessory and spare-part association for this model — the parts Omron itself couples to it for commissioning and for maintenance. Buying them together avoids the usual problem of a spare unit arriving without the bracket, key or battery needed to run it.

Ordering This Part

Send us the full catalogue number CP1H-X40DT-D, the quantity, your delivery address and the date you need the goods. If the part is a replacement, attach a photograph of the existing unit’s nameplate — it removes any doubt about the revision, the output type or the supply voltage, which are the three things that most often cause a wrong part to be shipped.

We do not publish stock, condition or lead time as fixed figures here, because they change: they are quoted per enquiry against the quantity and date you actually need. If a machine is down, say so and give us the required window — that is the information that determines how we source it.

Frequently Asked Questions

What does the -D suffix mean?

DC supply and transistor outputs. The CP1H-X40DT-D runs from 24 V DC and has transistor outputs; the relay-output and AC-supply variants of the same CPU carry different suffixes. Tell us your supply and load type and we will confirm the matching catalogue number.

How much panel space does it need?

150 mm wide, 90 mm high, 85 mm deep and approximately 600 g per Omron’s official catalogue data. That is the widest CP1H CPU module, so allow for it in a compact enclosure.

Can I add Ethernet?

Not as a CPU feature — the CP1H has a USB programming port and zero on-board Ethernet ports. Ethernet is added with a CP1W-CIF41 option board (listed among the accessories below), which is the usual route for CP1H installations that need network access.

Programming environment?

CX-One / CX-Programmer for the CP series. Omron’s CX-One Lite licence (CXONE-LT01-EV4) is listed with this CPU and supports the CP1H.

Production status?

Current — no end-of-production or discontinuation notice in Omron’s official catalogue data.
