1SVR740712R2200 ABB Control Industrial Automation Components

ABB 1SVR740712R2200 is a temperature controller with an analog interface, designed for thermistor motor protection. It features a thermistor motor protection relay, options for auto, manual, or remote reset, dynamic interrupted wire detection, short-circuit detection, and a test button. The device has DPDT (Double Pole Double Throw) - 2C/O contacts, with housing rated at IP50 and terminals at IP20. It supports a control voltage for DIN rail mounting, with normally closed (NC) auxiliary contacts accommodating both flexible and rigid wires of specified sizes. The controller operates on a 50/60 Hz frequency, with control circuit rated currents for AC and DC applications, and offers a variety of protection functions including a rated insulation voltage of 300 V and a rated impulse voltage (Uimp) of 4 kV. The supply voltage is compatible with AC 110-130 V and AC 220-240 V circuits, designed for over 100,000 operations, with analog outputs rated for 30,000,000 operations. The net dimensions include a height of 103.7 mm, a communication protocol width of 85.6 mm, and a depth of 22.5 mm. The device's terminals are made from a Silver-Nickel alloy (Ag / Ni) and are cadmium-free (Cd-free). Indicators include 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 spring, with a minimum operating temperature of -25°C and a maximum of +60°C. The short circuit current breaking capacity (Icn) and protection settings are designed for both AC and DC circuits, ensuring compatibility with a wide range of applications.
