4-24L12S is an Edwards EST4 control display module with 24 LED indicators and 12 control buttons. It snaps into the inner door of EST4 cabinets and annunciators. Each indicator position has five LEDs (red, yellow, blue, green and white), and the color and flash rate are chosen at configuration time. The rubber buttons give tactile feedback, and the associated indicator flashes briefly when a button is pressed.
