The scenario
Design of a smart street lighting system with three lighting circuits controlled by intelligent nodes (photocell + RS-485) that manage contactors for remote monitoring and scheduling.
What is in this drawing
Read the decisions behind it.
01
Used switch_load nodes to represent smart control units in the power path
02
Separated control logic (smart nodes) from load switching (contactors) to allow low-power smart control of high-current lighting circuits
03
Included energy metering for consumption tracking
When designing urban street lighting infrastructure with remote monitoring and control capabilities, especially where multiple circuits are managed via contactors and communication nodes.
