Siemens 7SJ8031-5EB00-1FQ0

The Siemens 7SJ8031-5EB00-1FQ0 is a compact overcurrent protection relay housed in a flush-mounting case designed for 19-inch rack installations. This device features multiple input and output options, including four current inputs, three voltage inputs, three binary inputs, and five binary outputs—with two of these configured as changeover contacts—as well as a live status contact. It supports measuring inputs rated at 1A or 5A for both current and earth fault detection. The relay operates reliably across a range of auxiliary voltages, accommodating DC supplies of 60V, 110V, 125V, and 220V, as well as AC supplies of 115V and 230V. Distributed by BSP Automation, this relay offers a versatile and robust solution for overcurrent protection in various industrial applications.
