1SVR550127R1100 ABB Control Industrial Automation Components

ABB 1SVR550127R1100 is an analog timer featuring an OFF-delay electronic timer/delay relay function that operates without the need for auxiliary voltage, ensuring a true OFF-delay. It is equipped with SPDT (Single Pole Double Throw) - 1C/O contacts, housed in an enclosure rated at IP50 and terminal protection rated at IP20. This timer is designed for DIN rail mounting and supports control voltages for AC circuits ranging from 24-240 V and DC circuits at 24 V. It is capable of handling supply voltages up to 100,000 operations and is designed to replace products with Silver Cadmium Oxide (AgCdO) contacts. The analog outputs are rated for 30,000,000 operations, with a tripping curve of 0.1-10 seconds. The trip unit type is a screw-clamp with a control circuit rated current of 4 A at 230Vac for AC-12 applications, 3 A at 230Vac for AC-15 applications, and 4 A at 24Vdc for DC-12 applications, with a short circuit current breaking capacity (Icn) of 2 A at 24Vdc for DC-13 applications. The timer operates within a temperature range of -20°C to +60°C and includes normally closed (NC) auxiliary contacts compatible with various wire sizes and types.
