1 normally open contact, potential-free 5A/250V AC. 230V LED lamps up to 50W, incandescent lamps 1000W. Standby loss only 0.5 watts. For flush mounting. 45mm long, 45mm wide, 18mm deep. State-of-the-art hybrid technology combines the advantages of wear-free electronic control with the high performance of special relays. Control input with internally generated low voltage 24V DC. Galvanically isolated from the power supply and the working contact (PELV) with an isolating transformer. Therefore, no external low voltage power supply is required. The distance between the power supply and the working contact is 6 mm. Power supply 230V.
