Description: The HSDQ chip solution is adopted, and two chips are used to stabilize the surge withstand voltage, the load current is large (70% load current), and the surge withstand voltage is high (1200V). And two optocouplers are used, which are highly sensitive, fast breaking, and anti-breakdown, that fully improves the safety of solid state relays. High temperature resistant and flame-retardant shell, makes it moisture-proof, anti-explosion, corrosion-resistant, silent, sparkless. The built-in nut is quenched, and wire will never slip during wiring. The wiring board is made of red copper, which has good conductivity and corrosion resistance. And the circuit is designed with dual triode protection, and the control end is more stable. Made of high quality PVC material, it's odorless, harmless, and durable. The bottom plate is made of pure aluminum, which has heat dissipation effect. This relay length is 9.5cm, width is 2.5cm, height is 3.1cm. The industrial solid state relay is suitable for automatic process control application, a must component for temperature controller and other machinery control system Item Name: Industrial Solid State Relay Material:Aluminium,PVC Input Voltage: 4-32VDC Ambient Temperature: -30 degrees Celsius - 75 degrees Celsius Rated Current: 80A(1), 100A(2), 120A(3), 150A(4), 180A(5), 200A(6) Load Voltage: 30-480VAC Control Current: DC 3-25mA Power-off time: ≤10ms Medium Voltage Resistance: 2500V AC Status Indication: LED Surge Withstand Voltage: 1200V Size:9.5cmx2.5cmx3.1cm/3.74inx0.98inx1.22in Notes: Due to the light and screen setting difference, the item's color may be slightly different from the pictures.
