The Phoenix PLC-OSC-24DC/48DC/100 (Part No: 2966728) is a precision-engineered solid-state relay module with a 2-conductor floating output circuit and secure screw connection terminals. Operating at a nominal input voltage of 24 V DC, it accepts an input voltage range of 19.2 V to 28.8 V DC, making it versatile for integration into modern PLC-controlled circuits. It uses an electronic 1 N/O contact configuration and supports an output voltage range of 3 V DC to 48 V DC, allowing seamless control of medium-voltage DC loads.
The relay supports a limiting continuous current of 100 mA and maintains a voltage drop ≤ 1 V at peak load, ensuring stable and energy-efficient operation. With a fast response time of 20 µs and turn-off time of 300 µs, this module handles quick switching cycles without mechanical wear or noise. Built-in reverse polarity and suppression diode protection enhances long-term reliability. The integrated yellow LED indicator offers visual confirmation of operating status, and the DIN rail mounting with a 6.2 mm slim width helps conserve panel space in dense installations. Whether you’re replacing outdated relays or designing a new system, the Phoenix 2966728 offers performance you can trust in critical industrial settings.
Engineers working in manufacturing, automation, and building control systems choose this module for its low maintenance, high-speed response, and strong electrical protection. The relay is valuable in use cases such as pulse switching, feedback loop triggering, and digital signal interfacing. Its solid-state design eliminates contact bounce and mechanical failure, which is especially beneficial in high-frequency switching environments with vibration or electrical noise. The PLC-OSC-24DC/48DC/100 is reliable for both replacement and OEM projects, reducing troubleshooting time during commissioning or plant maintenance.
