AI Thread Summary
Relays that can operate with both AC and DC are essential for the design of an Auto Start Control panel. A 24VDC relay can be used to activate the start signal when the relay is de-energized, but the challenge lies in integrating both the 24 VDC signal and the 120 VAC power loss. A suggested solution involves using a rectifier, voltage divider, diode, and capacitor to convert the 120VAC signal into a 24VDC signal. This creates two signals: Signal A (24VDC present) and Signal B (derived from the AC). The relay can then be configured to activate based on the presence of Signal A or the absence of Signal B.

Are there relays which work with both AC and DC? I am design an Auto Start Control panel which will activate on a 24 VDC power signal OR loss of 120 VAC power. I am using relays to accomplish this and I am not very familiar with them.

I was thinking a 24VDC relay connected to the 24 VDC signal. This relay will activate the signal when relay is deenergized ( I still have to figure out how to accomplish this if the DC signal the relay is monitoring is normally not energized). I am just not sure how to accomplish having the start signal with both a 24 VDC signal and 120 VAC. This is supposed to be designed into a simple control panel. Cannot be very complicated due to time restraints (This is a work project, not school). Should I use a rectifier?

You can use a voltage divider, a diode and capacitor to turn the 120VAC signal to 24VDC. Call that signal B. Signal A is 24VDC present. Then the relay activates when A or NOT B.

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...

Thread 'EMF (Electromagnetic Field) & EHS (Electromagnetic Hyper Sensitivity)'

Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
