Types of Signals
Orbex differentiates signals into power circuits and signal circuits. In general, a power circuit is used to transfer power to the rotating portion of the machine, not to transfer data. Depending on the slip ring family, power circuits can transfer 5, 10, 15, or 20 amps per circuit, and standard voltages up to 600 VAC. Higher voltages and higher currents are available as custom configurations.
Signal circuits are normally rated at 2 amps/circuit, and are normally used to transfer data, or power that is lower voltage and less than 2 amps per signal. Signal circuits are often used to transfer digital data, but this will be selected in the next section since high speed data often needs special cabling, shielding and/or termination.
