The Youtai PS2501 with Optocouplers is a device that utilizes Optocouplers to isolate current, power, and data signals between two circuits. The Optocouplers are housed in a through-hole package and are RoHS compliant. The device provides 4 channels of electrical isolation, has an insulation voltage (between output pins) of up to 5000Vrms, and stands to temperatures between -40 and +85°C. It also delivers a high photo-current of 60mA with a low offset voltage of 2.5V. The device is used mostly in signal transmission/conditioning, conversion, photocoupler applications, communication systems, industrial field bus system, LED lighting systems, and more.
