1SVR740850R0300 ABB Control Industrial Automation Components

ABB 1SVR740850R0300 is a liquid level controller designed for liquid level monitoring with a relay function. It features 3 x electrodes and DPDT (Double Pole Double Throw) - 2C/O contacts, housed in an enclosure rated IP50 and terminal blocks rated IP20. The control voltage is specified for DIN rail mounting with a communication protocol width of 85.6 mm. It has a net height of 4 kV and a rated impulse voltage (Uimp) of 22.5 mm. This controller offers dry running protection and overflow protection with a rated insulation voltage (Ui) of 300 V and a total height of 103.7 mm. It operates with a control voltage of AC 24Vdc at 0.6 W and supports both flexible and rigid wires in its connections. The supply voltage ranges from AC/DC 24-240 V, ensuring compatibility with various power sources. The product is designed for a high number of operations, with contacts made from a Silver-Nickel alloy (Ag / Ni) and is cadmium-free (Cd-free). It has an analog output rated for 1 000 000 operations and a frame current rating that varies with the supply voltage. The net width includes indicators: a green LED for control/supply voltage presence, and yellow LEDs for electrode/alarm status and output relay energization. It features a tripping curve of 0.1-10 s, spring-type trip unit, and terminals suitable for a wide range of wire sizes. The minimum operating temperature is -25°C, and it can handle a control circuit rated current up to 4 A at 230Vac for AC-12 applications, with a maximum temperature of +60°C. The short circuit current breaking capacity (Icn) and protection settings are designed for both AC and DC circuits, with a processing time and measurement function that supports an operating rate of 0.1-1000kΩ.
