Features:
- ABB identity: HIEE401481R0001 UAC326AE01 retains the complete page model while preserving the manufacturer table mapping.
- Documented role: combined I/O spare for UNITROL P.
- System quantity: ABB lists two modules per UNITROL P system.
ABB’s spare-parts flyer links the Identification and Type columns used to verify HIEE401481R0001 UAC326AE01.
The documented quantity describes the UNITROL P architecture and should not be treated as a site-specific replacement instruction.
Cabinet position, connectors, and project drawings remain the practical compatibility boundary for service work.
Apter Power provides exact-model document review, quotation, and procurement support for the ABB HIEE401481R0001 UAC326AE01 Combined I/O Module.
