Delta Electronics DOP-W157B DOP-W Series Human Machine Interface

Description

Designed for robust visualization and control on the factory floor, the DOP-W157B represents the high-performance tier of Delta Electronics' DOP-W Series human machine interfaces. This operator panel provides clean graphical representation and reliable monitoring capabilities for medium-to-large industrial automation systems. By integrating seamlessly with programmable logic controllers (PLCs), motor drives, and distributed control systems, it serves as an efficient operations hub for plant engineering environments.

The unit features a high-density liquid crystal display housed in a rugged enclosure designed to withstand demanding physical conditions. Its passive thermal design prevents internal dust accumulation, while standard mounting provisions ensure secure integration into control desks and system panels. Robust hardware and communication configurations allow for stable, continuous process display and industrial network connectivity.

Features

• High-luminance 15-inch TFT LCD display providing sharp visual resolution under varied lighting conditions.
• Extended LED backlight lifespan engineered for continuous industrial operations.
• Robust front-panel protection rating safeguarding internal electronics from liquids and dust.
• Natural convection cooling system that eliminates the failure points associated with mechanical fans.
• Integrated Real-Time Clock (RTC) for precise event logging, scheduling, and system alarms.

Applications

• Oil and Gas control monitoring systems
• Water and Wastewater treatment facility HMIs
• Power Generation and distribution control panels
• Automated Packaging and material handling processes
• Food and Beverage production lines

Installation Guidelines

• Panel Mounting: Ensure the panel cutout dimensions closely match the specified installation dimensions. Evenly torque the mounting clamps to maintain the IP65/NEMA4 seal against the enclosure wall.
• Ventilation Clearance: Allow a minimum of 50mm clearance around all sides of the HMI unit to prevent heat buildup and ensure proper passive air circulation.
• Wiring and Grounding: Connect the dedicated system ground terminal to a low-impedance earth ground. Route communication and control cables away from high-voltage AC power wiring to prevent electromagnetic interference.
• Environmental Limits: Do not install the unit in environments where the ambient operating temperature exceeds 50 degC or falls below 0 degC.

Compliance and Certifications

• CE
• UL
