It provides one normally-open and one normally-closed delayed auxiliary contact, with the delay adjustable from 1 to 30 seconds. The block is off-delay only — there is no on-delay function. Rated operational current for the auxiliary contacts varies by voltage: 4 A at 24 V, 2 A at 48 V, 0.7 A at 110 V, 0.3 A at 220 V, 6 A at 230 V, 4 A at 400 V, 2.5 A at 500 V, and 1.5 A at 690 V. The contacts are rated AC-12 at 10 A maximum. The block clips onto the contactor front — no additional DIN rail space needed. Dimensions are 45 mm wide, 45 mm high, 60 mm deep. Mounting position is any orientation. The front is IP20 finger-safe. Connections are screw-type terminals accepting solid or stranded wire: 2x (0.5…1.5 mm²) and 2x (0.75…2.5 mm²), or AWG 20…14. Finely stranded wire with ferrule uses the same ranges.","metaTitle":"Siemens 3RT2927-2PR01 SIRIUS Pneumatic Off-Delay Block, 1-30","metaDescription":"Siemens SIRIUS 3RT2927-2PR01 pneumatic off-delay block for S0 contactors.
