Question regading rectifer circuits

[howie]

Can someone suggest to me a mulitple input AC to DC converter chipset or any rectifier chip that converts 220Vac to 5Vdc.

The scenario is this, in a conrtrol panel, there are lamp indicators that lights up upon completion of each process (flood control process) i need to detect each lamp indicator as it activates so that I could remotely control each devices through ethernet. But the problem is all lamps are 220Vac and the "data logger" device that I made only accepts 5Vdc as digital inputs. Note that each control panel have atleast 22 lamp indicators that's why i need a multiple input converter.

Can I know your opinions to solve this problem.

Thanks.

Well firstly, your indicators should run at 220VAC for simplicity. As for the 5V signals, have you considered just using relays? They are cheap (or at least, cheaper than an AC->DC converter) and get the job done (where I work relays are literally like rice grains as to our surplus quantity).

I know it's really old-tech, but if you aren't switching really fast a relay would be really good since I know for a fact they sell 220VAC relays and you can just hook up 5VDC to the switch to signal your data logger.
