The SIR1A20A4 is a solid-state relay in the SIR series, designed for industrial applications with normally open SPST configuration, random switching for inductive loads, and a 20 A steady-state, 200 A inrush output rating at 120 V ac. It operates with a 9 to 30 V ac/dc control voltage range, features optical isolation, and is mounted via a single #10 screw on a metal surface requiring heat sink compound. The relay measures 50.8 mm × 50.8 mm × 38.4 mm and terminates in 0.25 in. male quick-connect terminals. It is UL and CSA certified for use in enclosed industrial controls.
The SIR1A20A4 relay provides solid-state switching protection with input voltage from 9 to 30 V ac/dc and output voltage at 120 V ac.
