Industrial LM4821-5614A Control Panel is a vintage Solatron control panel that centers on a Densitron LM4821 display module. The LM4821 is documented as a four-line by twenty-character LCD display module, a common core readout in industrial instrument panels, and LM4821-5614A appears as a specific variant of this configuration. This unit combines Solatron's rugged control-panel architecture with Densitron's LM4821 LCD, serving as the operator interface for legacy equipment that requires a compact, textual display for process parameters and status messages.
