Phoenix Contact ST Series Power Optocouplers ST Series pluggable power optocouplers give you a great selection of easy connection technology. This series offers a wide range for directly switching with small capacities of output module actuators, such as contactors, solenoid values or motors. Plug-in power solid-state relays in this series have a protective circuit in input and output circuits and are mountable in basic terminal blocks. Features and Benefits: • Yellow LED operating voltage display
• Wear-free switching of 24 V DC/5 A and 240 V AC/1 A
• Protection circuit against interferences in input and output
• Defined input level
• Direct control possible with voltage levels from 5 V to 230 V
• Electrical isolation between input and output
• Protection against polarity reversal
• High switching frequency
• Noise reduction
• Vibration resistant Typical Applications: Power optocouplers are generally designed for industrial applications, from power engineering to process technology. Optocouplers have a longer service life and provide isolation between input and output circuits along with signal amplification. Other applications include vehicle, control cabinet, and ships.
