Description

High-speed, high-accuracy analog control is delivered by the Omron CJ1W-DA042V, a specialized 4-channel analog output module engineered for the Omron CJ-Series PLC platform. This module converts digital values inside the PLC into analog voltage signals, providing high-speed direct conversion capabilities to interface with variable speed drives, actuators, control valves, and other analog field instruments.

Featuring individual channel configuration, the CJ1W-DA042V supports independent signal range selection for each of its four outputs. The system's ultra-fast conversion cycle, scaling down to 20 microseconds for a single point, makes it exceptionally suited for dynamic motion control and high-speed process modulation where real-time accuracy is critical.

Features

  • Four independent, high-precision analog output channels.
  • Supports wide signal ranges: 1 to 5 V, 0 to 10 V, and -10 to 10 V.
  • Adjustable resolution up to 1/40,000 for high-precision control requirements.
  • Ultra-fast direct conversion mode with conversion times as fast as 20 microseconds.
  • Independently configurable output signal ranges per channel.
  • Equipped with a removable terminal block for simplified installation and maintenance.
  • Occupies a single unit number allocation on the PLC backplane.

Applications

  • High-speed positioning and servo drive speed control.
  • Precision process control loop modulation (valves, dampers, actuators).
  • Dynamic test bench and laboratory automation systems.
  • Industrial manufacturing and packaging line automation.

Installation Guidelines

Mounting: Securely mount the module onto the CJ-series CPU rack or expansion rack. Ensure the locking levers at the top and bottom of the unit are fully engaged to guarantee proper connection to the backplane.

Wiring: Use shielded twisted-pair cables for analog output connections to minimize electromagnetic interference. Route signal lines away from high-voltage power cables or motor lines.

Grounding: Connect the shield wire of the output cables to the ground terminal of the PLC system or control panel. Ensure a single-point ground is maintained to avoid ground loop currents.

System Maintenance: Always power down the PLC system before removing or attaching the terminal block or the module itself to protect sensitive internal CMOS components from ESD and voltage surges.

FAQ

What is the conversion speed of the CJ1W-DA042V?

The conversion period depends on the number of active points configured: 20 us for 1 point, 25 us for 2 points, 30 us for 3 points, and 35 us for 4 points.

Can I configure different voltage ranges for each output channel?

Yes, the signal range selection can be configured separately for each of the four output channels.

What analog output resolutions does the Omron CJ1W-DA042V support?

It supports a resolution of 1/10,000 for the 1 to 5 V range, 1/20,000 for the 0 to 10 V range, and 1/40,000 for the -10 to 10 V range.

Does the module feature a removable terminal block?

Yes, the module is designed with a removable terminal block, simplifying installation, testing, and maintenance procedures.
