The Phoenix PLC-OPT-24DC/48DC/100 (Part No: 2900352) is a versatile solid-state relay module that supports a 24 V DC nominal input voltage and operates within a reliable input range of 19.2 V DC to 28.8 V DC. Its electronic 1 N/O contact and 2-conductor floating output circuit provide efficient signal switching in modern PLC-based applications. With a 300 Hz transmission frequency and a response time of just 20 µs, this relay offers fast, bounce-free operation, especially for low-current output switching up to 48 V DC.
The module supports a limiting continuous current of 100 mA and maintains a low voltage drop ≤ 1 V during operation, minimizing heat generation and power loss. Its push-in connection terminals simplify field wiring and reduce installation time, making it ideal for densely packed control panels. Equipped with a yellow LED indicator and reverse polarity protection, this relay enables safe diagnostics and long-term stability. Its DIN rail mounting, 6.2 mm width, and vibration resistance make it suitable for compact industrial setups that demand high reliability and service-free switching. Designed for universal use, the Phoenix 2900352 module stands out for its balance of precision, safety, and ease of integration.
Its compact size and push-in connection terminals allow fast installation in space-limited cabinets. The fast response time and absence of mechanical parts eliminate wear and contact bounce, making it highly suitable for continuous operation in industrial automation, process control, and building management systems. Whether you're upgrading old relay banks or implementing energy-efficient DC circuits, the PLC-OPT-24DC/48DC/100 helps reduce maintenance efforts and improves long-term system stability.
