ZCI11 Relay Socket 11 Position DIN Rail - Equivalent & Substitute Parts

Part Overview

The ZCI11 is an 11-position relay socket manufactured by Carlo Gavazzi Inc., designed for DIN rail mounting applications. This component serves as an interface for RCI relay modules, providing screw terminal connections for secure electrical integration. The ZCI11 is currently classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ZCI11 is determined by the following critical parameters:

• Number of Positions: Must be 11 to maintain electrical interface compatibility
• Mounting Type: Must be DIN Rail to ensure mechanical fit within existing installations
• Termination Style: Must be Screw Terminal for connection method compatibility
• Type: Must be Socket to function as a relay interface component

The ZCI11 is compatible with RCI relay modules. Substitute parts must maintain these four core parameters to ensure direct functional replacement without system redesign or mechanical modification.

Parameter Comparison

Engineering Selection Recommendations

The ZPD11A is identified as the manufacturer-recommended substitute for the obsolete ZCI11. Both components share identical electrical and mechanical specifications across all critical parameters: 11-position configuration, DIN rail mounting, and screw terminal termination.

The primary distinction is product status: the ZCI11 is obsolete while the ZPD11A is active and currently in production. The ZPD11A is manufactured by the same supplier (Carlo Gavazzi Inc.), ensuring consistency in quality and manufacturing standards.

Selection of the ZPD11A is supported by its active product status and manufacturer recommendation, providing assurance of continued availability and supply chain stability for future procurement cycles.

Frequently Asked Questions (FAQ)

Q: Can the ZPD11A directly replace the ZCI11 in existing installations?

A: Yes. Both components maintain identical specifications for number of positions (11), mounting type (DIN rail), termination style (screw terminal), and socket type. Direct mechanical and electrical substitution is possible without system modification.

Q: What is the significance of the series designation change from RCI to ZPD?

A: The series designation identifies the product line within the Carlo Gavazzi portfolio. While the ZCI11 belongs to the RCI series and the ZPD11A belongs to the ZPD series, both are 11-position DIN rail relay sockets with screw terminal connections, meeting the functional requirements for substitution.

Q: Why is the ZCI11 classified as obsolete?

A: Obsolete status indicates the component is no longer in active production. The ZPD11A represents the current active alternative for new procurement and system maintenance.

Q: Are there compatibility considerations with relay modules?

A: The ZCI11 is specified for use with RCI relays, while the ZPD11A is specified for use with RCP relays. Relay module compatibility should be verified against the specific relay type in your application before final component selection.

Q: What inventory status should be considered for procurement?

A: The ZCI11 shows 1126 pieces in stock (obsolete status), while the ZPD11A shows 1186 pieces in stock (active status). For new designs and long-term system support, the ZPD11A is the recommended choice due to its active product status and ongoing availability.
