Built by Phoenix Contact, the OPT-5DC/24DC/5 miniature solid-state relay features robust basic insulation and a test voltage of 2.5 kV between input and output, ensuring safety across critical circuits. It accepts a 5 V DC nominal input, with a flexible range of 4 V to 6 V DC, drawing a typical input current of 9 mA. The relay’s fast 10 µs response time and 400 µs turn-off time allow rapid, reliable switching in dynamic environments. Its output voltage spans from 3 V DC to 33 V DC, with a 5 A continuous current rating and support for 15 A inrush over 10 milliseconds. Thanks to its low voltage drop (≤ 200 mV), it ensures stable performance during high-speed operations. The 2-conductor floating output circuit is supported by built-in reverse polarity protection and polarity protection diode, enhancing durability and circuit protection. Certified under ISA-S71.04 G3 Harsh Group and compliant with IEC 60664 standards, this model is designed for tough environments.
The OPT-5DC/24DC/5 is widely deployed in industrial PLC control systems, motion control setups, and automated test benches where silent and spark-free switching is critical. Maintenance engineers prefer it in environments with high cycle switching, where mechanical relay wear is a concern. Its compact size makes it ideal for space-constrained panels, and the -25°C to 60°C operating range ensures dependable operation even under thermal stress. Engineers working with microcontroller-based outputs often rely on this relay for its low activation current and reliable DC load handling. Whether you're building new machinery or retrofitting legacy systems, this solid-state relay offers a low-maintenance, long-life alternative to traditional electromechanical relays.
