480 VAC pilot Lights
480 VAC pilot Lights
(OP)
I have old (40y) TG control panel with about 30 pilot lights.
About 10 of those lights are 480VAC. What i want to do is to bring all of those lights to the PLC HMI. However 480 VAC presents the problem.
Cannot modify the source of the 480VAC pilot lights.
Short of installing step down transformer on every light what are my other options? Could not find any interposing relays with 480 VAC coil.
Any feedback is appreciated.
Thank you

The alternative is to use a small IEC type contactor with a 480VAC coil. Not as small as an interposing relay, but in a crunch will work.

Some industries are moving away from even 120 V ac control circuits and converting to 24 V dc.

The prints I had for this Panel date back to 1954. However, somewhere along the lines someone changed 480 VAC lights to 125 VAC.
Thank you for tips
