Red Lion Controls MDI2Y11A Indicator Display

Red Lion Controls MDI2Y11A is a panel-mount indicator/display unit designed to present machine- or process-related messages on a compact 2-by-20 character transmissive LCD. With a capacity for up to 256 messages and a built-in real-time clock/calendar, it can timestamp entries and sequence displays for diagnostics or operator guidance. The display supports scrolling and blinking characters to draw attention to critical messages, and its yellow-green backlight enhances legibility in industrial environments. The MDI2Y11A accepts 115 or 230 VAC input and uses screw-clamp terminals for secure wiring; its panel-mount form factor makes it suitable for instrument panels, control consoles, or nearby enclosures. Note that this model has been discontinued by Red Lion, so availability may be limited and replacements or service options might be through third-party repair providers. Typical applications include process indicators, alarms, and operator guidance on control panels.
