Light dimmer control panels

Need to know the voltage, ac or dc and amperage for each circuit...does the dimmer control the voltage or run a program...how many total circuits, are they all the same?...what is the application, industrial, commercial, residential, hospital, warehouse, restaurant, museum, theater?...is this an automated or strictly manual system...

Who cares what failing technology had been installed? What do your local codes call for controlling an unknown voltage source powering an unknown load? In other words, you have given us nothing, not even which hemisphere this system resides. We cannot help you when we know nothing about the system.

On second thought, yes you have given us enough information to help you. You don't recognize what critical information is needed to be known to do this work. You are not qualified to do this work. You should hire a local electrician or electrical engineer to do this work.

This looks like something that was a high-end product in the 1980s or 1990s. Lighting and control technology has improved tremendously in the last five years, so it is quite obsolete. I would use this as an opportunity to get complete replacement proposals from electrical contractors specializing in lighting systems. Modern LED lighting is much more efficient; in a commercial building the savings in electricity could pay for the cost within several years. Many electrical utilities offer rebates for upgrading to more efficient lighting, so check that when calculating cost/benefit.

You may find the new control designs to be much more convenient. Some systems can be run with a secure app installed on the phones of authorized users, or through the building network. Many can automatically adjust the lighting to account for the contribution of external daylight through windows, and use occupancy sensors to turn off lights that aren't needed. That eliminates a lot of running over to the control panel to set the lights.

Note: This looks like low-voltage circuitry in the input panel board, so you have a bit of leeway for repairs. If cash is too scarce to buy new lighting right now, you may be able to find a replacement switch for the "Off" button on an old computer keyboard or at an electronics surplus store. If it's a self-latching switch (push-on, push-off) rather than setting the state in the electronics with a momentary switch, you may be able to use a mute switch from a junk audio mixer. You might end up using tape to hold the panel on or something ugly like that, but as long as it does the job safely, it perhaps could be made to hold up long enough to accumulate the necessary funds for replacement.
