Relay socket Finder 90.21SMA – relay socket tester for Finder relay series 60.13 and 88.02

Finder 90.21SMA is a relay socket designed for use with Finder relay series 60.13 and 88.02. It provides a stable connection interface between plug-in relays and control wiring, enabling straightforward installation, replacement and electrical testing in control cabinets and automation panels. The socket supports quick relay swapping without rewiring and is compatible with common DIN-rail mounting arrangements used in industrial and building automation environments.

Advantages

The relay socket offers a compact footprint and a robust contact system that ensures reliable electrical continuity over repeated insertions and removals. It simplifies maintenance by allowing relays to be replaced or tested without disturbing surrounding wiring. The design accommodates standard terminal connections for easy integration into existing control systems, and its compatibility with Finder relay series 60.13 and 88.02 ensures correct mechanical and electrical fit.

Suitable for

• Control cabinets and distribution panels
• Automation and PLC interface modules
• Maintenance and diagnostic tasks requiring quick relay replacement
• Testing and commissioning of relay-based circuits

Key specifications

• Compatibility: designed for use with Finder plug-in relays in the specified relay series
• Mounting: suitable for DIN-rail mounting in control enclosures
• Connection type: screw or push-in terminals for control and load wiring (model-dependent)
• Contact durability: engineered for multiple insertion/removal cycles to support maintenance operations
• Electrical interface: provides fixed relay contact terminations for clear wiring layout and testing access

How to use

Mount the relay socket on a DIN rail inside the control cabinet and secure the socket according to the panel layout. Connect incoming and outgoing conductors to the terminal points following wiring diagrams and safety standards. Insert the compatible Finder relay into the socket until it seats firmly; verify correct orientation before powering the circuit. For testing, remove the relay as needed and use test equipment at the socket terminals or with a relay tester designed for the specified relay series.

Usage recommendations

Ensure power is disconnected before wiring or inserting/removing relays. Use the socket with the designated Finder relay series to maintain correct electrical ratings and mechanical fit. Periodically inspect terminal screws or connectors for tightness and signs of wear; replace the socket if contact reliability is compromised.
