Voltage protection relay MSR

DCACmounting

Controlling the electromechanical contacts with pulse-shaped voltage avoids unwanted switching. This protects the contacts and prolongs their service life due to a dropout delay. Specially recommended for liquid-filled measuring instruments. Technical data Supply voltage AC 230 V, 50 – 60 Hz Power input 6 VA Control voltage DC 35–40 V pulse Switching output MSR 010: 1 x voltage-free changeover contact MSR 020: 2 voltage-free changeover contacts MSR 011: 2 voltage-free changeover contacts Contact rating: AC 250 V, 8 A, 2,000 VA Supply voltage DC 24 V, max. 20 mA for external devices or LED indicators Operating temperature range Ambient: 0/70 °C Housing DIN rail mounting 35 x 7.5 mm as per EN 60715 W x H x D: 50 x 75 x 97 mm Degree of protection: IP 20 (EN 60529)
