1SVR730850R0200 ABB Control Industrial Automation Components

ABB 1SVR730850R0200 is a liquid level controller designed for liquid level monitoring with a relay function. It features 3 electrodes and SPDT (Single Pole Double Throw) contacts with a 1C/O configuration. The housing is rated IP50, and the terminals are rated IP20 for protection. It has a control voltage of DIN rail and supports a supply voltage range of AC/DC 24-240 V. The controller is equipped with dry running protection, overflow protection, and has a rated insulation voltage (Ui) of 300 V. The net height and width are 103.7 mm and 22.5 mm, respectively, with a control circuit rated current of 4 A at 230Vac for AC-12 and 3 A for AC-15, and 4 A at 24Vdc for DC-12 and 2 A for DC-13. It offers a frame current rating of 0.025 A at 24Vdc, 0.02 A at 110-130Vac, and 0.0085 A at 220-240Vac. The device includes a green LED for control/supply voltage presence, a yellow LED for electrode/alarm status, and a yellow LED to indicate output relay energization. It supports a wide range of wire sizes for flexible and rigid wires, with screw-clamp terminals for secure connections. The operating temperature ranges from -25°C to +60°C, and it has a short circuit current breaking capacity (Icn) suitable for various applications. The product is designed for easy installation on a DIN rail, features a silver-nickel alloy (Ag/Ni) for contacts, and is cadmium-free (Cd-free).
