Phoenix Contact Optocoupler, 24V - PSR-PS21-1NO-1NC-24DC-SC - 2700357
This optocoupler from Phoenix Contact provides you with a simple and reliable way of adapting your power or isolating a device in your electrical circuit. It's designed for simple mounting on a DIN rail and has a compact width of just 6.8mm, so it takes up minimal space. An isolation voltage of 3500V and a maximum forward voltage of 24V make it suitable for both high and low-power circuits.
The coupler relay features a corrosion-resistant protective coating on the PCB (printed circuit board) for enhanced performance. It meets IEC (International Electrotechnical Commission) standard 61508 for the design of electrical safety systems, so you can be sure it's safe to use. The filtering of controller test pulses increases the mechanical lifespan to a maximum of 10,000,000 cycles, so it's an efficient and long-lasting component. Use this product in automated production lines in light industry and telecommunications networks.
