PLC-RPT-24DC/21-21 – 24V DC Relay Module with Dual Changeover Contacts | Phoenix Contact

The PLC-RPT-24DC/21-21 relay module by Phoenix Contact is a compact and reliable switching interface, specifically built for 24 V DC control circuits in industrial automation. While it ensures fast integration, it also delivers precise switching through two independent changeover contacts (DPDT). Moreover, its modular design, push-in connection, and DIN rail mounting make it ideal for high-density control cabinets.

Thanks to its integrated input circuit and interference suppression, this ensures long-term operational stability. Furthermore, compatibility with V8 adapters and functional plug-in bridges allows for clean and efficient system cabling. As a result, this relay module reduces wiring time and enhances system maintainability.
