Description

Designed for precise digital-to-analog signal conversion within industrial automation systems, the CJ1W-DA041 serves as a high-performance analog output module for the Omron CJ series. This module enables programmable controllers to interface directly with analog control devices by converting digital process values into corresponding voltage or current signals.

Equipped with four high-accuracy channels, the CJ1W-DA041 supports standard industrial output ranges including 1 to 5 V, 0 to 5 V, 0 to 10 V, -10 to 10 V, and 4 to 20 mA. It features a removable 18-point terminal block that facilitates direct wiring and convenient system maintenance, minimizing downtime during module replacement.

Features

Four independent, configurable analog output channels.
Supports multiple voltage and current output ranges for broad instrument compatibility.
Fast digital-to-analog conversion period of 1.0 ms per point.
Photocoupler isolation between backplane controller signals and output circuits.
Configurable output hold function to maintain, clear, or maximize output signal states during PLC stop or error conditions.
Removable 18-point M3 screw terminal block for streamlined installation and wiring.

Applications

Proportional valve positioning and control systems.
Variable frequency drive (VFD) speed regulation.
Process controllers, chart recorders, and remote indicators.
Multi-axis motion profiling and industrial heating control loops.

Installation Guidelines

Always disconnect the power supply to the CJ-series PLC rack before mounting or removing the analog output module.
To prevent electromagnetic noise, use shielded twisted-pair cables for all analog output connections and ground the shield only at the receiving end.
Route analog signal wires through dedicated conduits separate from high-voltage cables and AC power lines.
Ensure the external 24 VDC power supply complies with the startup inrush current specifications (20 A peak) to prevent power drops during module initialization.

Key Features:

#Analog Output Units #Omron CJ Series

What is the conversion speed of the CJ1W-DA041?

The D/A conversion period for the CJ1W-DA041 is 1.0 ms per point.

Does the CJ1W-DA041 support individual channel isolation?

No. While the module features photocoupler isolation between the I/O signals and the controller logic, there is no isolation between the individual output channels.

What happens to the analog outputs when the PLC controller stops?

The module features an output hold function. Depending on your configuration, it can hold the last state, clear the output (CLR), or set the output to maximum values (MAX).

Can the CJ1W-DA041 output both voltage and current simultaneously?

Yes, each of the 4 channels can be configured independently for either voltage (e.g., 0 to 10 V) or current (e.g., 4 to 20 mA) output ranges.
