Application-Specific FAQ
Q: Is the AAR145-S50 compatible with CENTUM CS 3000?
A: Yes. The AAR145-S50 is backward-compatible with Yokogawa CS 3000 I/O nests and can be used as a direct replacement for legacy AO modules in CS 3000 systems with appropriate firmware revision.
Q: Can this module be used in a redundant AO configuration?
A: Redundant AO configurations in CENTUM VP typically require paired modules with the appropriate redundancy coupler. Contact our technical team to confirm the correct redundancy architecture for your application.
Q: What is the maximum cable length for 4–20 mA field wiring?
A: With a maximum loop resistance of 750 Ω and standard 0.5 mm² shielded cable (~36 Ω/km), field runs up to approximately 1,000 m are achievable. Always verify against your specific cable specification and load device impedance.
Q: Do you provide a warranty on refurbished units?
A: Yes. All tested and refurbished units carry a 90-day functional warranty. New-in-box units carry the standard Yokogawa manufacturer warranty where applicable.
Q: Can Konmask.com assist with CENTUM VP system integration?
A: We specialize in component supply. For full system integration services, we can refer you to certified Yokogawa system integrators in your region.
