CP1L-EM30DT-D

Product information

Product Overview

The CP1L-EM30DT-D is Omron’s CP1L-E compact PLC in the Ethernet variant: 18 DC inputs and 12 transistor (NPN) outputs — 30 built-in I/O — on 24 V DC supply, with a built-in Ethernet TCP/IP port, 20 K steps of program capacity and 2 positioning axes.

This page is written for buyers and maintenance engineers sourcing CP1L-EM30DT-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) › CP1L-(E). Official catalogue code for this model: CP1L-EM30DT-D.

Why Buyers Specify This Model

Ethernet built into the CPU, USB not

Omron’s specification lists one built-in Ethernet TCP/IP port and no USB port. That is the key difference from the CP1L variants with serial and USB — programming and HMI communication go over the network.

30 built-in I/O on 24 V DC, transistor outputs

18 inputs and 12 NPN outputs are integrated. Expansion reaches 3 units and a maximum of 150 local I/O points, with 2 PTP axes at 100 kHz and 4 encoder input channels.

Analog option boards supported

Omron states analogue option boards are supported on this model, with a maximum of 34 analog I/O channels — covering the small mixing, dosing and temperature loops typical of CP1L-E applications.

Compact footprint

130 mm wide, 90 mm high, 85 mm deep, approximately 455 g, with a 0.55 µs LD execution time.

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 CP1L-EM30DT-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

CP1L-EM or CP1L-M — what is the difference?

The EM variant has built-in Ethernet; the M variant does not and relies on option boards for communication. Choose EM when the machine has to sit on a plant network or talk to a panel PC without extra hardware.

No USB port — how do I download the program?

Over Ethernet, using CX-Programmer. If you need USB, the CP1L-M or CP1H variants provide it; if you need serial, CP1W-CIF01/CIF11/CIF12-V1 option boards are listed with this model.

Does it support analog inputs?

Yes, via CP1W analog option boards — for example CP1W-ADB21 for two 0 to 10 V / 0 to 20 mA analog inputs and CP1W-DAB21V for two analog outputs, both of which are specific to the CP1L-EL/EM variants and are listed in the accessories section.

Availability?

Current production; Omron’s official catalogue data shows no end-of-production notice.
