Applications

Crystal Specialties Incorporated was a manufacturer of crystal growth equipment and process controllers based in Irwindale, California. The Model 510 Programmer is a step-sequencing controller used to automate multi-stage thermal or process cycles — such as the carefully controlled temperature ramp-up, hold, and cool-down sequences required in crystal growth furnaces (e.g., Bridgman, Czochralski, or flux-growth systems). The programmer advances through numbered steps at defined time intervals, triggering relay and contactor outputs that control external heating elements, motors, valves, or other actuators at each stage. Alarm outputs allow the system to monitor process limits and alert or shut down the process if a parameter goes out of range. This type of programmable sequence controller was standard equipment in research labs, university materials science departments, and industrial crystal growth operations from the 1980s through the 2000s. It may also find use in other laboratory process automation applications requiring timed, multi-step relay sequencing with alarm monitoring.
