1SVR740021R2300 ABB Control Industrial Automation Components

ABB 1SVR740021R2300 is a multifunction electronic timer and delay relay equipped with control input for voltage-related triggering. It features a variety of functions including ON-Delay, OFF-Delay with auxiliary voltage, Impulse ON, Impulse OFF with auxiliary voltage, symmetrical ON- and OFF-delay, Flasher Starting with ON / OFF, Star-delta change-over with impulse, Pulse Former, Accumulative ON-delay, and ON / OFF Function. This part has DPDT (Double Pole Double Throw) - 2C/O contacts, with a housing speed rating of IP50 and terminal speed rating of IP20. It is designed for DIN rail mounting, supports control voltages in the range of AC 380-440 V, and has a supply voltage durability of 100,000 operations. The analog outputs are rated for 30,000,000 operations. The frame current rating varies with voltage: 0.0012 A at 24Vdc, 0.008 A at 230Vac, and 0.006 A at 400Vac. The net width is indicated by a green LED for control/supply voltage presence and timer activity, with two yellow LEDs for output relay energization. It offers a wide timing range of 0.05s-300h / 0.05-1,080,000 s. The earthing system is based on a spring mechanism, and it operates within a temperature range of -25°C to +60°C. The device has a short circuit current breaking capacity (Icn) of 4 A at 230Vac for AC-12 and 3 A for AC-15, as well as 4 A at 24Vdc for DC-12 and 2 A for DC-13.
