ELR-7B intermediate relay 230V AC 1xSPDT 1X16A

Intermediate relays, also known as intermediate or interposing relays, are electrical devices used in control and automation systems to provide an interface between different components, such as switches, sensors, and higher-capacity power relays or contactors. They serve as an intermediate or intermediary device to control a high-current or high-voltage circuit using a low-current or low-voltage control signal. Intermediate relays play a crucial role in simplifying complex control systems and enhancing safety and flexibility. Intermediate relays amplify and isolate control signals. They take a weak input signal, often from a sensor or a low-voltage control switch, and use it to control a higher-power output circuit. ELR intermediate are designed for DIN rail mounting, making them easy to install and integrate into control panels or enclosures.
