CJ1W-DA041

Product information

Product Overview

The CJ1W-DA041 is Omron’s CJ-series 4-channel analog output unit for the CJ I/O Bus — a Special I/O Unit that drives four analog actuators, valves or variable-speed drives from the PLC. Output resolution is 12 bit.

This page is written for buyers and maintenance engineers sourcing CJ1W-DA041 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) › CJ2 › CJ Analogue I/O and Control Units. Official catalogue code for this model: CJ1W-DA041.

Why Buyers Specify This Model

Four output channels across four signal ranges

Each channel is selectable to -10 to 10 V, 0 to 10 V, 0 to 5 V, 1 to 5 V or 4 to 20 mA, so the same unit can drive a 0–10 V control valve and a 4–20 mA drive on different channels.

12-bit output resolution

Omron’s catalogue gives 12 bit output resolution for this unit.

Detachable screw terminal block

Screw termination with a detachable block, so a failed unit can be exchanged without disturbing the field wiring.

Not a safety unit

Catalogue classification: not suitable for safety functions.

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.

Ordering This Part

Send us the full catalogue number CJ1W-DA041, 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We do not publish stock, condition or lead time as fixed figures here, because they change: they are quoted per enquiry against the quantity and date you actually need.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 is the difference from the CJ1W-DA041 and the AD041?

The AD041 reads analog signals in; the DA041 writes them out. They share the same 31 mm width, 90 mm height, detachable terminal block and CJ I/O Bus interface, so the two are usually installed side by side.

Which output range should I choose?

Match the receiving device: most industrial drives and positioners accept 4 to 20 mA for noise immunity over long cable runs, while local control valves often use 0 to 10 V. The range is set per channel, so you can mix.

Does it need external power for the outputs?

The unit is powered from the rack backplane. Field wiring requirements (shielded twisted pair, separation from mains cable) are set out in Omron’s official CJ-series analog I/O operation manual, linked below.

Availability?

Current production — no discontinuation notice in Omron’s official catalogue data.
