I've seen 24VDC on these "Continuity" type switches before from multiple OEMs. You connect 24VDC to the Common of a Sourcing Input module and switch the ground or negative side of the power supply to the input terminal. Or you connect 24VDC to a relay coil and switch the 0VDC/Ground side of the power supply to the relay to turn it on/off. Some have used continuity level sensor modules to do it. Many different ways to do it.
Recently I've had a few cases where operators have reported being "shocked" by these devices. Usually on the more tender parts of a body, like the underside of your arm if it touches it.
I've always considered 24VDC a "Safe" voltage level. But there is some definite pain involved when touched just right or under the right circumstances (humidity, sweating, etc.)
Is there a way to easily limit the current available on these types of devices? I've been trying to figure out what I can do in a parallel or series circuit to control available current on the setup but haven't found anything yet.
(Not 100% sure if current is even my issue here.)
