Questions & Answers
💡 FAQ
Q: Can IS420UCSBH4AH work as a drop-in replacement for IS420UCSBH3A?
A: Physical mounting is identical. Firmware update on the whole Mark VIe system is required to run IS420UCSBH4AH in racks originally using IS420UCSBH3A.
Q: Does this controller module come with preloaded firmware?
A: Firmware is not preloaded. The site engineering team loads the matching firmware version during commissioning.
Q: Can I run one IS420UCSBH4AH alone without a redundant partner?
A: Simplex operation is allowed for non-critical loops. Redundant pair setup is common for main turbine control loops.
Q: What is the payment method?
A: T/T
Q: What is the warranty?
A: 1 year
Q:What are the available shipping methods?
A: FedEx, DHL, UPS, and others.
