Specifications: The OPT1210E is a compact through-hole DIP-4 relay engineered for medium-voltage switching with robust isolation. It carries a 150mA, 350V (AC/DC) rating with a 15Ω typical on-state resistance. A key feature is its 5000Vrms isolation, ensuring high safety margins. It switches with 230μs turn-on and 50μs turn-off times. Designed for industrial longevity, it performs reliably from -40°C to 85°C, activated by a standard 1.2-1.4VDC logic signal.
Application Scenarios: This relay is a staple in industrial control and instrumentation where through-hole mounting is preferred. It is used for isolating analog sensor signals from data acquisition systems, switching auxiliary power to transmitters in process control loops, providing a high-voltage interface for vacuum fluorescent displays (VFDs), and in power supply control circuits, offering a reliable and safe switching solution.
