13 Oct 2009 3:06 Question regarding Multiple input AC to DC converter module

Can someone suggest to me a multiple input AC to DC converter module or chipset that converts 220Vac to 5Vdc.

The scenario is this, in a control 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.
