Webb16 feb. 2024 · Relays would control other relays to form logic controllers. For example with a simple AND gate, only when 2 inputs are energised, this one AND this one, does the relay output energise. These inputs could be sensors or they could be outputs from other relays.

The schematic diagrams for relay logic circuits are often called line diagrams, because the inputs and outputs are essentially drawn in a series of lines. A relay logic circuit is an electrical network consisting of lines, or rungs, in which each line or rung must have continuity to enable the output device.
