1SVR740740R0300 ABB Control Industrial Automation Components

ABB 1SVR740740R0300 is an analog temperature controller designed for analogue temperature monitoring relay applications, including under-/over-temperature monitoring, with 2 thresholds and window temperature monitoring. It features short-circuit detection and is equipped with 2 x SPDT (Single Pole Double Throw) - 2C/O contacts. The housing is rated at IP50 and terminals at IP20 for protection. The control voltage for DIN rail installation varies with 24Vdc consuming 0.8 VA, 115Vac at 1.5 VA, and 230Vac at 2.9 VA. It supports a control circuit rated current 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 device operates within a temperature range of -40°C to +60°C and can handle a supply voltage of 24-240 V AC/DC, with a frame current rating of 0.033 A for 24Vdc, 0.0125 A for 115Vac, and 0.013 A for 230Vac. The trip unit type is spring, and it is designed for over 30 million operations with analog outputs and a silver-nickel alloy (Ag/Ni), cadmium-free contact material. The minimum operating temperature is -40°C, and the maximum is +60°C, with a short circuit current breaking capacity (Icn) of 4 A for AC and 2 A for DC. The processing time and operating rate are optimized for temperatures ranging from 0 to 200°C.
