Phoenix Contact Solid State Relays

Solid state relays have no moving parts like electromechanical relays, but utilize electrical components and optical properties of solid state semi-conductors to perform IO switching functions and isolation. They are designed for applications that require high switching speed without arcing or contact noise. They are highly resistant to vibration and shock and are unaffected by the presence of dust, gases or other contaminants. Solid state relays are used in heating control applications for a compressor’s soft-start, fan, blower, heater and valve control. They are used in lighting applications for dimming and for their ability to operate silently and switch quickly. Because of their resistance to shock and vibration and non-arcing, motion control applications such as lifts, hoists conveyor systems and elevators are the perfect fit for solid state relays.

Phoenix Contact PLC-INTERFACE solid state relays have an overall width of just 14 mm with switching voltages up to 250 VDC and 10 A possible. The hybrid design ensures lower power dissipation and an increased service life, and offers the perfect compliment to the existing hybrid variants for AC voltages. The relays are highly reliable thanks to comprehensive load tests and high quality requirements. They offer safe switching of different DC loads due to optimized matching between the semiconductor and the relay.
