The ABB TA25DU-19 is a miniature, industrial-grade, 8-pin Octal Base Relay Socket. It is designed to securely hold and provide electrical connection to a standard 8-pin round (Octal) plug-in relay or timer (conforming to IEC 60715 dimensions). This socket serves as the interface between the removable relay and the control panel's fixed wiring. It provides screw terminal connections for easy wiring, allows for quick relay replacement without rewiring, and often includes a mechanical latch or clip to prevent accidental disconnection. The "-19" suffix likely indicates a specific variant, possibly with a metal clip or specific terminal type.
