Featuring a 4.5-inch monochrome LCD display with LED backlighting, it provides high-contrast visibility for up to 12 lines of text or process graphics simultaneously. The unit enables operators to view real-time data, adjust setpoints, and execute commands through a 24-key tactile membrane keypad, eliminating the need for a full industrial PC at the machine level.\u003c\/p\u003e\n\u003ch3\u003eKeypad Configuration and Tactile User Input\u003c\/h3\u003e\n\u003cp\u003eThe terminal incorporates a sealed 24-key membrane keypad designed for industrial panel environments, rated for over one million actuations. The keypad array includes numeric data entry keys, navigation controls, and 8 dedicated function keys that enable one-touch navigation to critical operational screens and alarm menus.\u003c\/p\u003e\n\u003cp\u003eIntegrated non-volatile flash memory stores up to 250 application display screens without requiring a battery backup. Internal capacitors provide up to 50 milliseconds of power ride-through during momentary voltage dips, ensuring an orderly system shutdown if power is fully interrupted.\u003c\/p\u003e\n\u003ch3\u003eMulti-Protocol Communication and Hardware Integration\u003c\/h3\u003e\n\u003cp\u003eDesigned for broad controller compatibility, the \u003cstrong\u003eHMI-L2P\u003c\/strong\u003e includes two RS-232 serial ports, one RS-485 port, and a USB configuration port. The serial ports interface directly with controllers from GE, Allen-Bradley, and Modicon, while the RS-485 port supports multi-drop networking across up to 32 field devices.\u003c\/p\u003e\n\u003cp\u003eThe unit operates on a 24 VDC nominal supply (18-30 VDC range) with a typical power consumption of 8 W. Mounting into a 6.8 x 5.3 inch panel cutout using included retention clips and front gasket provides NEMA 4X ingress protection against dust and washdown water.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eHMI-L2P\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eGeneral Electric\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Line\u003c\/td\u003e\n\u003ctd\u003eOperator Interface Terminals\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eOperator Interfaces\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDisplay Type\u003c\/td\u003e\n\u003ctd\u003eMonochrome LCD with LED Backlight\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDisplay Size\u003c\/td\u003e\n\u003ctd\u003e4.5 in diagonal (114 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eResolution\u003c\/td\u003e\n\u003ctd\u003e240 x 64 pixels\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eKeypad Type\u003c\/td\u003e\n\u003ctd\u003e24-key membrane with 8 function keys\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommunication Ports\u003c\/td\u003e\n\u003ctd\u003e2x RS-232, 1x RS-485, 1x USB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eScreen Storage Capacity\u003c\/td\u003e\n\u003ctd\u003eUp to 250 screens (Flash Memory)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Ride-Through\u003c\/td\u003e\n\u003ctd\u003eUp to 50 ms (Internal Capacitors)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSupply Voltage\u003c\/td\u003e\n\u003ctd\u003e24 VDC nominal (18–30 VDC range)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003e8 W typical\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIngress Protection\u003c\/td\u003e\n\u003ctd\u003eNEMA 4X (Front panel with gasket)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions (W x H x D)\u003c\/td\u003e\n\u003ctd\u003e7.2 x 5.7 x 1.8 in (183 x 145 x 46 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePanel Cutout (W x H)\u003c\/td\u003e\n\u003ctd\u003e6.8 x 5.3 in (173 x 135 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e0 to 50 deg C (32 to 122 deg F)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.45 kg (1.0 lbs)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003cp\u003eFrequently Asked Questions\u003c\/p\u003e\n\u003cp\u003eQ: How is the GE HMI-L2P powered, and what are its electrical requirements?
