DDC Panels / Starter Panels / Sequencing Panels

Panels that hold the controllers, switch the motors and share duty between equipment.

A DDC panel holds the controller, its I/O and the 24 V supply for a plant area. A starter panel switches and protects a motor, by direct-on-line, star-delta or soft starter. A sequencing panel shares duty between pumps or fans, rotating them by run hours and changing over on a fault.
