The OMRON CJ1W-DA041 is a 4-channel Analog Output Unit for the SYSMAC CJ-series PLC. It is a "Special I/O Unit" used to convert digital binary data from the PLC into standard analog signals to control devices like variable speed drives, proportional valves, or chart recorders.

Key Features and Capabilities

  • Multi-Range Support: Each of the 4 channels can be independently configured for different voltage or current ranges, allowing for diverse peripheral control.

  • High Precision: Offers a standard resolution of 1/4,000, which can often be scaled or adjusted depending on the specific CPU settings.

  • Fast Conversion: Features a conversion speed of 1 ms per point, ensuring responsive control for dynamic industrial processes.

  • Built-in Isolation: Includes photocoupler isolation between the output terminals and the internal PLC bus signals to prevent electrical noise from affecting the CPU.

  • Standard Connection: Uses a detachable screw terminal block, making it easy to wire or replace the module without disturbing the field wiring.
