Door control system with IDEC SmartRelaycircuit diagram
This is what the circuit diagram of the conventional solution
looks like.
You can simplify this circuit if you make use of the IDEC
SmartRelay functions. You can use the off-delay function to
replace the latching relay and the on-delay. The block
diagram below illustrates this simplification:
