ZPD8A – 8 PIN PLUG IN RELAY BASE

Why Choose the Carlo Gavazzi ZPD8A 8-Pin Industrial Relay Socket?

The Carlo Gavazzi ZPD8A is a robust and reliable 8-pin octal industrial relay socket designed for use with compatible Carlo Gavazzi RCP series electromechanical relays. As part of the Carlo Gavazzi ZPD relay socket range, it provides a practical mounting and wiring interface for industrial control systems, electrical panels and automation equipment requiring dependable plug-in relay connections.

Designed to accommodate DPDT (double-pole double-throw) relays with two changeover contacts, the ZPD8A features aligned screw-cage terminals that simplify conductor connection and maintenance. Its plug-in arrangement allows compatible relays to be installed or replaced without disconnecting the permanently wired socket, helping reduce maintenance time and improve serviceability.

With a rated current of 10 A, a rated voltage of 400 V AC and an IP20 protection rating, the ZPD8A is suitable for a wide range of industrial relay applications. The socket supports 35 mm DIN rail mounting and features a compact design measuring 61.4 × 38 × 26.2 mm, making it suitable for installation inside electrical control cabinets and industrial automation panels.

Reliable Relay Connections for Industrial Automation

Industrial relay sockets such as the Carlo Gavazzi ZPD8A provide a convenient electrical and mechanical interface between plug-in electromechanical relays and permanently installed control wiring. When a compatible RCP8 relay is inserted into the socket, its coil and contact pins engage with the socket connections, allowing control signals and switched circuits to be routed through the connected terminals. This arrangement simplifies installation, fault finding and relay replacement without requiring the socket wiring to be removed.

The ZPD8A relay socket is designed for professional electrical control applications where dependable connections and straightforward servicing are important. Its screw-cage terminals provide secure conductor termination, while the DIN rail mounting arrangement allows efficient integration into industrial control cabinets. The optional SZPD56M retaining spring can provide additional mechanical security where relay retention is required. The socket itself is a passive connection accessory and must be fitted with a compatible relay to provide switching functionality.
