Siemens 6ES7 131-4BF00-0AA0 Relay 6ES7 131-4BF00-0AA0

The relay, also known as switching relay, coupling element, or control relay, with type number 6ES7 131-4BF00-0AA0 from Siemens is an electrical component for controlling circuits. It has the dimensions 1.5 x 8 x 5.5 cm and weighs 0.035 kg. Relays serve to switch and isolate electrical circuits by opening or closing a separate load circuit via a control signal, thus enabling the control of larger powers with small control signals. They are typically used in industrial automation, in machine and plant control systems, and in building technology, to safely connect and disconnect electrical components.
