- Why 24VDC? | Automation Control Engineering Forum
24VDC is a standard there are some basic reasons for using 24VDC in industries 1 safety: 24DC will not generate sparks but if we go for a higher voltage, it may generate spark in case of a short circuit loose contact so 24 VDC can even use in Zone 1, Ex'd areas instruments

2 each 12VDC, 500mA solar modules (to acheive 24VDC operation $94 95 each 1 each 6 Amp hour battery $30 00 1 each 24VDC charge controller $183 00 Add some wire and misc hardware and your done The solar modules will last about twenty years or more So will the electronics The battery will have to be replaced every three to five years

For the sake of the end user, or more specifically the person that is troubleshooting problems in the cabinet, I always lean towards the solid blue for +24Vdc, and white with a blue stripe for the 24Vdc common Having a sea of solid blue wires is never a welcome sight for your tech's

- 24 VDC | Automation Control Engineering Forum
24VDC and 120VAC relays are 2 different items A 24VDC relay needs a DC signal to turn ON, where as a 120VAC relay needs an AC signal Now, saying that, it does not matter what voltage you are switching on the contacts (Normally Open Closed), you could have DC or AC Voltage on the contacts, but ONLY the required voltage to PULL it IN
- Control voltage, 24VDC or 230VAC
We always use 24Vdc for control circuitry, and use 110Vac for contactor coils etc (24Vdc coils generate so much heat when energised) Panels are designed so that 110Volt equipment is located together and away from 24vDC to alleviate interference and for safety Rob
