Delay modes and adjustment range
The 3RP1505-2AQ30: This SIRIUS relay supports ON-delay, OFF-delay, and additive ON-delay functions, plus pulse-shaping — all in one 22.5 mm wide housing. The adjustable time range spans 0.05 to 100 s, set via a front-panel potentiometer. Minimum ON period is 35 ms, and recovery time between cycles is 150 ms — factor this into the control logic when timing conveyor or pump start sequences.
Contact ratings and control supply
Thermal current (Ith) is 5 A — the continuous current the contacts can carry without damage, regardless of switching duty. The pickup threshold (initial value) is 0.85 of nominal, with a full-scale value of 1.1 — so it reliably picks up at 85 V and holds in up to 140 V.
Mounting and environmental limits
Mounting position is any — no derating needed for horizontal or vertical orientation. Dimensions: 103 mm high, 22.5 mm wide, 91 mm deep. Operating temperature -25 to +60 °C; storage and transport -40 to +85 °C. Degree of pollution 3 (conductive pollution or dry non-conductive that becomes conductive) means it suits industrial control panels without sealed enclosures.
