Additional Details

The TLP185 series photorelay consists of an input LED and an output phototransistor or photodiode array. When current flows through the LED, it emits light, activating the phototransistor/diode array, thus closing the relay. Typical specifications include input forward current, output voltage, on-resistance, and isolation voltage. Refer to the datasheet for the TLP185(YH-TPRSE(T) variant for precise electrical characteristics.

This device is designed for applications where safety and isolation are crucial, ensuring reliable performance in challenging environments.
