Features:
- Sunlight‑Readable 1000 cd/m² Display
- Intelligent Thermal Management for Harsh Climates
- Hazardous Location Certification (Class I Division 2)
The Allen‑Bradley 2711P-RDT12H delivers an exceptional 1000 cd/m² luminance, making operator screens clearly visible under direct sunlight or in high‑ambient‑light environments such as outdoor drilling platforms, open‑pit mines, or agricultural machinery. This eliminates the need for shading or constant squinting, improving operator efficiency and safety.
Equipped with a built‑in temperature sensor, the Allen‑Bradley 2711P-RDT12H automatically reduces backlight intensity when internal cabinet temperature exceeds 55 °C (131 °F). This proactive feature prevents heat‑related damage to the display and extends service life in hot climates or poorly ventilated enclosures, without requiring user intervention.
The Allen‑Bradley 2711P-RDT12H is certified for use in Class I Division 2 (Groups A, B, C, D) and Class II Division 2 (Groups F, G) hazardous locations. This allows safe deployment in oil refineries, chemical plants, and grain processing facilities where flammable gases or dusts may be present, while maintaining full HMI functionality.
The 2711P-RDT12H Allen‑Bradley High‑Bright HMI Display Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

- Oil & Gas Field Equipment – Provides reliable HMI functionality on drilling rigs, wellhead control panels, and pipeline stations where direct sunlight and explosive atmospheres (Class I Div 2) are common.
- Mobile & Off‑Highway Machinery – Used in agricultural sprayers, forestry harvesters, and mining haul trucks, offering sunlight‑readable 1000 cd/m² displays that withstand high vibration and shock.
- Water & Wastewater Treatment – Outdoor pump stations and clarifier controls benefit from NEMA 4X/IP65 protection against hose‑down cleaning, humidity, and temperature extremes.
- Renewable Energy Installations – Solar tracker controllers and wind turbine nacelles often use this module because its high brightness and thermal management perform reliably under prolonged sun exposure and high ambient temperatures.
- Wide Temperature Range – Operates from 0 °C to 55 °C (32 °F to 131 °F) and survives non‑operating extremes from –20 °C to 70 °C, suitable for unheated enclosures or desert climates.
- High Humidity & Wet Conditions – With IP65 and NEMA 4X ratings when properly mounted, the module resists low‑pressure water jets, condensation, and corrosive atmospheres (e.g., coastal or chemical plants).
- Vibration & Shock Resistance – Certified to withstand 2 g vibration and 15 g operational shock, making it ideal for equipment mounted on engines, compressors, or mobile platforms.
- Direct Sunlight & UV Exposure – Designed for outdoor use with optional anti‑glare overlay (2711P‑RGT12) that blocks UV radiation, preventing bezel fading, yellowing, and brittleness over years of sun exposure.
- Hazardous Location Certification – c‑UL‑us listed for Class I Division 2 (Groups A,B,C,D), Class II Division 2 (Groups F,G), and Class III. Permits installation in areas with flammable gases or combustible dusts without requiring an explosion‑proof enclosure.
- Low Voltage & EMC Compliance – CE marked to EN 61131‑2 (LVD) and EN 61000‑6‑2/‑4 (EMC), ensuring safe electrical operation and electromagnetic compatibility in industrial environments.
- Mandatory Earth Grounding – Requires a low‑impedance earth ground connection (14–10 AWG) for operator safety, noise immunity, and compliance with EU EMC directive. The ground terminal is internally bonded to DC‑ on most variants.
- SELV/PELV Power Requirement – Must be powered by a safety extra‑low voltage (SELV) or protective extra‑low voltage (PELV) 24V DC supply per local wiring codes, which limits fault energy and protects personnel from electric shock.
