A multiple heater control system includes cables, connectors, and junction boxes for user-friendly daisy chain connections of heater controllers and heaters in various configurations or combinations of individually controlled heater series and/or master and slave heater series. The heater controllers include process control of AC power to the heaters and upper-limit safety shutoff that is substantially independent from the process control. The heater controllers also have variable levels of control, adjustment, display, and communications functionality in a base module that is expandable to various levels with expansion modules that are attachable to and detachable from the base module. Connector, cable, and junction configurations, adapters, and latch features enhance user friendliness.

Heater control with high-limit thermal safety shutdown

A power control system has a controller housing, a power switch disposed within the controller housing for selectively providing power from a power supply to a power load, a limiter disposed within the controller housing configured for providing a limit switching function in response to a threshold limit, and a controller disposed within the controller housing and configured for controlling one or more operations of the control system.
