1SVR740700R0100 ABB Control Industrial Automation Components

ABB 1SVR740700R0100 is an analog temperature controller designed for thermistor motor protection with an auto-reset feature. It features a Single Pole Double Throw (SPDT) contact type, with a housing speed rating of IP50 and terminal speed rating of IP20. The device has a communication protocol width of 85.6 mm, a net height of 4 kV, and a rated impulse voltage (Uimp) of 22.5 mm. It offers protection functions at 300 V and a rated insulation voltage (Ui) of 103.7 mm. The control voltage operates on a DIN rail with Normally Closed (NC) auxiliary contacts accommodating flexible wires of 2 x 0.5-1.5mm2 or rigid wires of 2 x 0.5-1.5mm2, and also flexible wires of 2 x 18-16AWG or rigid wires of 2 x 20-16AWG. The device operates at a wavelength of 50/60 Hz, with a number of circuits at 24 V AC/DC supply voltage, and is designed for 100,000 operations. It is made with a Silver-Nickel alloy (Ag / Ni) and is Cadmium-free (Cd-free). The analog outputs are designed for 30,000,000 operations. The net width is indicated by a green LED for control/supply voltage presence, a red LED for fault messages, and a yellow LED when the output relay is energized. The trip unit type is a spring, with a minimum temperature of -25°C and a maximum temperature of +60°C. The control circuit rated current is 4 A for AC-12 at 230Vac, 3 A for AC-15 at 230Vac, and 4 A for DC-12 at 24Vdc, with a short circuit current breaking capacity (Icn) of 4 A for DC-12 at 24Vdc and 2 A for DC-13 at 24Vdc. The protection settings and processing time are designed to operate within these parameters, with a measurement function that ensures accurate temperature control.
