Coil runs on 24 VDC (the only listed rated control voltage on the data plate), so it drops directly onto the standard 24 V control rail that already feeds PLC outputs and contactor coils — no separate transformer stage. ## Timing range and what it sets Adjustable time spans 0.05–100 s on a single scale (initial 0.8, full-scale 1.1), and the minimum ON period of 35 ms with a 150 ms recovery time tells the integrator the relay is built for sub-second sequencing rather than hour-long process delays — read it as a control-circuit timer, not a long-duration process timer. ## Contact rating in real load terms One delayed SPDT relay output, 5 A thermal continuous, with the contact ratings tabulated at 1 A / 24 V, 0.2 A / 125 V and 0.1 A / 250 V — read those as the tested switching envelopes, not the absolute maximums; the 5 A thermal figure is the continuous-carry ceiling, and the lower switched-current values reflect what the silver-alloy contact reliably breaks at each voltage level. ## Panel fit and mechanical install Wiring accepts solid or stranded 20–14 AWG conductors, basic insulation rated for degree-of-pollution 3 environments, with operating ambient −25 … +60 °C and storage −40 … +85 °C — it survives an unheated panel section and a tropical control room alike.","metaTitle":"Siemens 3RP1505-1AA40 timing relay, 0.05–100 s, 24 VDC","metaDescription":"Siemens SIRIUS 3RP1505-1AA40 timing relay with ON-delay, OFF-delay, additive ON-delay and pulse-shaping functions.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Time Delay Relays"],"specifications":{"Depth":"91 mm","Solid":"20 ... 14","Width":"22.5 mm","title":"3RP1505-1AA40","Height":"102 mm","Upwards":"0 mm","at 24 V":"1 A","Forwards":"0 mm","ON-delay":"Yes","Stranded":"20 ... 14","at 125 V":"0.2 A","at 250 V":"0.1 A","Backwards":"0 mm","Downwards":"0 mm","OFF delay":"Yes","At The Side":"0 mm","description":"Timing relay, Multifunction Phased-out product!!!
