I don't know if that's because they're from Japan or if that's just what robot manufacturers use, but it is a PITA for us to interface to and always leads to longer troubleshooting time, as we recall that the current isn't supposed to flow the same direction as everything else in the plant :) So an individual might have to (or find it advantageous to) use NPN switches for a particular job. The main advantage of relays is that the low power An example of relay is the act of getting a message to someone. The difference between relays and time delay relays is when the output contacts open & close: on a control relay, it happens when voltage is applied and removed from the coil; on time delay relays, the contacts can open or close before or after some time delay.

Selecting the correct relay is critical to the reliability of the controller and the integrity of the switched signal. They come in contact, complete the load circuit and our load is turned ON. On the secondary side, we have our load circuit, the circuit on which we have to perform the switching, connected between the normally open and common terminal of the relay. Simplicity. If you have them hooked to small relays, and they're close by, you're probably ok. Usually the power supply for either the SS or relay outputs is more than large enough to kill the transistor or vaporise the pcb trace connecting the relay. All these factors play a major role in making the system more efficient and safe. Especially when they are 24VDC! The armature is present at the end of the coil which is pivoted at a point and can move towards the yoke of the electromagnet if the coil is energized. Distance protection.
