The OPT-60DC/24DC/2 from Phoenix Contact is a high-performance Single Solid-state Relay designed to handle 60 V DC input and reliably switch up to 3 A of current within a 3–33 V DC output range. The device minimizes voltage drop to just ≤150 mV under full load, reducing heat and maximizing energy efficiency. With a swift 40 µs response time and 500 µs turn-off delay, this relay is ideal for rapid digital switching in automated systems. It features a 2-conductor floating output with reverse polarity protection and is enclosed in a compact 5 mm-wide RT III-rated housing that withstands harsh industrial environments. The basic insulation, 2.5 kV test voltage, and compliance with IEC 60664 and ISA-S71.04 G3 Harsh Group standards make it suitable for long-term use in aggressive and vibration-prone conditions.
