Commissioning note — time relay for sequence control
The Siemens SIRIUS 3RP1505-2BQ30 is a time relay with both ON-delay and OFF-delay functions, adjustable from 0.05 to 100 s via the front dial. The control supply accepts 100 … 127 V at 50 or 60 Hz, and the relay output switches 1 A at 24 V, 0.2 A at 125 V, or 0.1 A at 250 V. Mounts by screw or snap-on onto standard 35 mm DIN rail, occupying 22.5 mm of panel width.
Panel integration — DIN rail fit
The relay snaps onto 35 mm DIN rail or can be screw-mounted. Its 22.5 mm width and 103 mm height fit standard enclosure cutouts; depth is 91 mm including the terminal plane. Mounting position is any, and operating temperature range is -25 to +60 °C, so it can sit in a warm cabinet provided airflow is adequate.
