Signal Cables are used to transport electrical signals generated by various blocks in Electrical Age. Signal cables can transmit both digital and analog signals. These signals can be used directly to control devices such as relays, heat furnaces, signal processors, etc. Through these mechanisms signal cables can be wired to control generator systems, lighting circuits, mob farms, traps, and numerous other applications.
Signal cables follow the same placing rules as electrical cables. Signal cables will not connect to electrical cables, making it safe to run them next to high-voltage lines. Signal cables do not have an internal resistance, therefore cable length can be ignored when creating circuits. Devices that interact with signal cables all have a specific side for cable output. If a device does not automatically connect to a neighboring signal cable after placement, it must be rotated by right-clicking it with a wrench.
