Phoenix Contact 2900378 Solid-State Relay Module

The PHOENIX CONTACT 2900378 solid-state relay module is a compact and versatile solution for controlling DC loads in industrial applications. Featuring electronic PDT contact and push-in connection, it is designed for mounting on DIN rail NS 35/7.5. The module provides wear-free switching with no contact bounce, resistance to vibrations and shocks, and protective circuits in both input and output. It is suitable for bridging adjacent modules and offers DC voltage outputs up to 300 V DC/1 A or up to 24 V DC/10 A. The module's electronic PDT output supports voltages up to 48 V DC/500 mA and includes a status indicator for easy monitoring.
