Frequently Asked Questions (FAQ)

Q1: What signal types does the SEA4D-01 support?

A1: It supports both 4–20 mA current outputs and 0–10 V voltage outputs per configurable channel.

Q2: Can the output channels be configured independently?

A2: Yes, each of the 4 output channels can be configured independently for voltage or current output.

Q3: What is the accuracy of the analog output?

A3: The output accuracy is ±0.1% of the full scale.

Q4: Is the module isolated?

A4: Yes, each channel is isolated from the others and from ground to prevent cross-talk and improve safety.

Q5: Which systems is SEA4D-01 compatible with?

A5: It is compatible with Yokogawa’s STARDOM FCN and FCJ series controllers.

Q6: How is the module mounted?

A6: It is DIN-rail mountable for easy and secure installation in control panels.

Q7: What is the power requirement for this module?

A7: It operates at 24 V DC ±10%, consuming approximately 4.5 watts.

Q8: Can the module be used in outdoor environments?

A8: The module should be housed in a protective enclosure if used outdoors, as it is not IP-rated on its own.

Q9: What kind of maintenance does it require?

A9: It is designed for long-term use with minimal maintenance. Periodic calibration checks are recommended.

Q10: Is software configuration required?

A10: Yes, initial configuration is done through Yokogawa’s engineering tool or STARDOM configurator software.
