I was wondering if anyone could tell me if the following relay exists, or can be easily built using off the shelf parts? I need to monitor 3 x 240V inputs and switch 1 x 240V output. However, every time one of the inputs is activated, I need the output to disengage for a period of time before re-engaging. So as an example: 1. Input 1 is 240V. Output goes to 240V. 2. Input 1 is off. Output goes to off. 3. Input 2 is 240V. Output goes to 240V. 4. Input 1 goes to 240V. Output goes to off for 'x' seconds, then goes to 240V. 5. Input 2 is off. Output stays on. 6. Input 1 is off. Output goes to off. I've looked into building a custom relay using an arduino for the control logic, but was hoping there was a solution I could just buy. I've taken a look at the DMB51CM24 Carlo Gavazzi and this seems to do what I want, but only for a single input. Whereas, I require 3 inputs.
