1SVR550851R9500 ABB Control Industrial Automation Components

ABB 1SVR550851R9500 is a liquid level controller designed for liquid level monitoring with a relay function. It features 2 electrodes and 1 Normally Open (NO) auxiliary contact. The housing is rated at IP50, and the terminals are rated at IP20 for protection. It supports a control voltage for DIN rail mounting and accommodates various wire types and sizes for connection, including flexible wire with ferrule (2 x 0.75-1.5mm2), flexible wire (2 x 1-1.5mm2), and rigid wire (2 x 0.75-1.5mm2), also supporting 18-16AWG sizes. The device operates at a frequency of 50/60 Hz, with a supply voltage for AC 220-240 V and is designed for 300,000 operations, with the contacts made from Silver Cadmium Oxide (AgCdO) for extended life up to 30,000,000 operations. The net width indicator is a yellow LED that remains steady when the output relay is energized. It utilizes screw-clamp terminals for secure connections, operates within a temperature range of -20°C to +60°C, and can handle control circuit rated currents of 4 A for AC-12, 3 A for AC-15 at 230Vac, and 4 A for DC-12, 2 A for DC-13 at 24Vdc. The short circuit current breaking capacity (Icn) and protection settings are tailored for specific operational requirements, with a processing time and measurement function suited for a wide range of liquid level monitoring applications.
