Product Details And Specifications

Delta DOP Series: Comprehensive Module Range and Technical Overview

The Delta DOP Series represents Delta Electronics' primary Human-Machine Interface (HMI) product line, deployed across global heavy industry sectors including petrochemical plants, nuclear power auxiliary systems, oil refineries, water treatment facilities, and discrete manufacturing. With installations spanning Asia-Pacific, Europe, and the Americas, the DOP Series has established a dominant position as a cost-effective, field-proven HMI platform compatible with Delta's DVP and AS series PLCs as well as third-party controllers via standard communication protocols (Modbus RTU/TCP, PROFIBUS, EtherNet/IP, CANopen).

The DOP-A10TCTD is a 10.1-inch TFT LCD capacitive touch panel within the DOP-A sub-series, featuring 1024×600 resolution, dual Ethernet ports, USB host/device interfaces, and support for up to 8,000 internal memory registers. It is rated for industrial environments with an operating temperature range of 0–50°C and front panel IP65 protection.

The Evolution of DOP Series Architecture

The DOP Series has progressed through three distinct architectural generations since its introduction in the early 2000s:

Generation 1 — DOP-A Series (2003–2010): Based on ARM9 processors with resistive touch technology, serial RS-232/RS-485 communication, and proprietary Delta Screen Editor software. Display sizes ranged from 3.5 to 10.4 inches. These units are now fully discontinued and classified as end-of-life (EOL) by Delta Electronics. Replacement parts including touch glass, backlights, and main boards are no longer available through official channels, making third-party MRO suppliers the only viable source for lifecycle extension.

Generation 2 — DOP-B Series (2010–2018): Introduced ARM Cortex-A8 architecture, resistive and capacitive touch options, expanded communication ports (Ethernet, USB), and compatibility with DOPSoft 2.x. This generation remains in active use across installed bases globally. Some models have entered the discontinuation phase, with Delta providing limited spare parts support.

Generation 3 — DOP-100 / DOP-W Series (2018–Present): Current production platform. Features ARM Cortex-A9 dual-core processors, capacitive multi-touch, HDMI output options, 64-bit color TFT displays, and DOPSoft 4.x compatibility. Backward-compatible with DOP-B project files via conversion utility. This generation represents Delta's strategic direction for new installations.

Compatibility note: DOP-A and DOP-B series units use different communication cable pinouts and power supply specifications. Direct substitution between generations requires hardware adaptation and software migration.

Sourcing Hard-to-Find & Obsolete DOP Series Parts

The DOP-A Series has been fully discontinued by Delta Electronics, and the DOP-B Series is progressively entering end-of-life status. For facilities operating legacy DOP-A and DOP-B installations — particularly in long-lifecycle environments such as chemical processing, power generation, and water infrastructure — unplanned downtime caused by HMI failure represents a critical operational risk.

DriveKNMS maintains a dedicated inventory of surplus, refurbished, and new-old-stock (NOS) DOP Series units and spare components, including:

• Complete HMI panel assemblies (DOP-A and DOP-B series)
• Replacement touch glass panels (resistive and capacitive)
• LCD backlight assemblies and display modules
• Main control boards and power supply units
• Communication interface cards (RS-232, RS-485, Ethernet)

All sourced units are cross-referenced against Delta's official part number database to ensure compatibility. DriveKNMS provides lifecycle extension support with a minimum 12-month warranty on refurbished assemblies and full traceability documentation for regulated industries.

Quality Control for the DOP Series Range

DOP Series HMI panels integrate complex backplane communication buses, capacitive touch controllers, and multi-port Ethernet PHY circuits that require protocol-level validation beyond standard power-on testing. DriveKNMS applies the following test procedures to all DOP Series units prior to shipment:

• Display verification: Full-screen pixel mapping test to identify dead pixels, backlight uniformity defects, and color calibration deviation.
• Touch controller validation: Multi-point capacitive touch accuracy test across the full active area; resistive linearity test for legacy units.
• Communication port testing: RS-232, RS-485, Ethernet (10/100/1000 Mbps), and USB ports tested under load using protocol analyzers.
• Modbus/EtherNet IP loop test: Each unit is connected to a test PLC and subjected to a 30-minute continuous register read/write cycle to validate bus stability.
• Thermal burn-in: 4-hour powered operation at 45°C ambient to screen for early-life component failures.
• Firmware integrity check: Verification of installed firmware version against Delta's release matrix; re-flashing performed where required.
