Selection Notes

SSD1A335M7C1 is the 90-280 V AC/DC control-input variant of the 35 A SSD1 relay, versus a 4-32 V DC control input on other SSD1 parts - pick this version when the control signal comes from a 120/230 V AC circuit, such as a PLC relay output or a 24-240 V control transformer, avoiding a separate interposing relay to step the control signal down to DC. Turn-on/turn-off response (20 ms/30 ms) is slower than the DC-input part's 0.5-cycle rating, reflecting the added input-side rectification and filtering needed for the wider AC/DC control range. Load-side rating (35 A, 48-600 V AC output, 7.46 kW/10 hp at 480 V AC) matches the DC-input 35 A part.
