Omron CJ1W-DA041 CJ Series Analog Output Unit

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.
