TLC5947: Looking for partner device

Part Number: TLC5947

Hello

We have received an inquiry below and we need your help to find a suitable device for him:

What I have is a TLC5947 that is driving 24 Crydom 2425 Solid State Relays to turn on 24 120V AC circuits for Studio Lighting. Actually I am doing this 48 times for a total of 1152 circuits in the lighting grids of our two studios. We have dimmer modules on every one of these circuits now and I am replacing the dimmer modules with the above parts in our two studios. We are converting to all LED Studio Lights and require non dimmable circuits.

What I have been asked to do now is to supply a return signal to the controlling computer that confirms that the SSR actually turns on the circuit. I will be using a MID400 that is designed just for that application. What I now need is a 24 channel logic sensor that will give me that information. I am thinking using a 24 channel device to compliment the 24 TLC5947 since all of the lighting circuits are in 24 channel configurations. I have designed each of the replacement modules to use the existing Dimmer Modules that each have a two pole 20A 120V Circuit Breaker built in. I gut all the rest of the electronics and replace it with a circuit board that has all the control wiring from the main computer. I have a  74LS02 on the output of the MID400 to give me both a positive or a negative pulse which will be fed to the Input of the computer for confirmation.

Thank you

Regards,

Roland
