Frequently Asked Questions (FAQ)

Q1: Can the SPASI23 be used to replace a SPASI13 module?

A: The SPASI23 is an evolved version with higher capabilities. While often backward compatible, we recommend verifying your master controller firmware version first.

Q2: Does this module require a specific termination unit (TU)?

A: Yes, the SPASI23 typically pairs with specific NTAI or NTAO series termination units. We can help you source the matching TU for your cabinet.

Q3: How do I verify the module firmware or hardware revision?

A: The revision is printed on the side label. We will provide high-definition photos of this label to ensure it matches your existing module configuration.

Q4: How fast can you ship for an emergency boiler or turbine trip?

A: We prioritize "Plant Down" emergencies. Express air freight typically delivers to major industrial centers in 3-5 business days.
