1SVR740850R2200 ABB Control Industrial Automation Components

ABB 1SVR740850R2200 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 housing protection rating of IP50 and terminal protection rating of 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 device 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 on a control voltage of 24Vdc consuming 0.6 W, and supports both flexible and rigid wires of specified sizes for connections. The supply voltage ranges from 110-130 V AC to 220-240 V AC, ensuring compatibility with various power supplies. 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 for up to 1 000 000 operations and a frame current rating that varies with the supply voltage. The device features a green LED for control/supply voltage presence, a yellow LED for electrode/alarm status, and a yellow LED to indicate when the output relay is energized. It utilizes a spring trip unit type and operates within a temperature range of -25°C to +60°C. The control circuit rated current varies with the voltage, and it has a short circuit current breaking capacity (Icn) suitable for various applications. The protection settings and processing time are designed for optimal performance, with an operating rate suitable for a wide range of measurement functions.
