Carlo Gavazzi Solid State Relay 1-Phase Zero-Cross RM1A48D50S18

Carlo Gavazzi Solid State Relay 1-Phase Zero Switching with LED & Built-In Varistor, Control: 4-32VDC, Operational: 480VAC, 50A, Option: S18.

The industrial, 1-phase relay with antiparallel thyristor output is the most widely used industrial SSR due to its multiple application possibilities. The relay can be used for resistive, inductive and capacitive loads. The zero switching relay switches ON when the sinusoidal curve crosses zero and switches OFF when the current crosses zero. The instant-on relay with DC control input can be used for phase control. The built-in varistor secures transient protection for the heavy industrial applications, and the LED indicates the status of the control input. The clipon cover is securing touch protection to IP 20. Protected output terminals can handle cables up to 16mm2.
