The relay output is rated 1 A at 24 V DC, 0.2 A at 125 V DC, and 0.1 A at 250 V DC — these are the switching limits for inductive or resistive DC loads; the thermal continuous current is 5 A. Width is 22.5 mm. Terminals accept stranded wire 20-14 AWG; tightening torque is 0.8-1.2 N·m. ## Timing and function This is a delayed-switching relay (ON-delay and OFF-delay are both selectable via the front dial). Recovery time is 150 ms, meaning the relay resets within that window after the control voltage is removed. The adjustable time range covers 0.05 to 100 s, set by a front potentiometer. Full-scale value tolerance is 1.1, initial value 0.85.","metaTitle":"Siemens 3RP1555-1AQ30 SIRIUS Time Relay, 0.05-100s, 100-127V","metaDescription":"Siemens 3RP1555-1AQ30 SIRIUS time relay, adjustable 0.05-100 s, control supply 100-127 V AC, 1 A at 24 V DC, screw/snap-on 35 mm DIN rail.
