Pro-face GP2300 Series: Comprehensive Module Range and Technical Overview

The Pro-face GP2300 series is a line of industrial Human-Machine Interface (HMI) touch panels manufactured by Digital Electronics Corporation (Pro-face), Japan. These units are deployed across global heavy industries including petrochemical plants, nuclear power facilities, oil refineries, and continuous-process manufacturing lines. The GP2300 series occupies the mid-range tier of the Pro-face product hierarchy, positioned between the entry-level GP2000 and the high-performance GP3000 lines. Its 24 VDC power input, STN/TFT color display options, and RS-232C/RS-422 communication ports made it a standard specification for SCADA front-end terminals and local operator panels throughout the 2000s and early 2010s. Installed base remains significant in facilities with long equipment replacement cycles, making spare parts availability a critical operational concern.

The Evolution of GP2300 Architecture

The GP2300 series was introduced as a successor to the GP2000 platform, retaining backward compatibility with GP-PRO/PBIII programming software while introducing a faster CPU core and expanded display resolutions. Early GP2300 units used STN monochrome and STN color displays with 320×240 (QVGA) resolution. Mid-cycle revisions introduced TFT color panels and expanded internal memory for larger tag databases. Communication architecture relied on RS-232C and RS-422/485 serial interfaces, with optional Ethernet connectivity available via add-on communication units (e.g., GP2000-TC41 Ethernet adapter).

The GP2300 series reached end-of-life (EOL) status as Pro-face transitioned its product line to the GP3000 and GP4000 series, which introduced USB host/device ports, CF card slots, and Ethernet as standard. Facilities running GP2300 units face compatibility constraints: GP3000 series panels require GP-Pro EX software, which does not natively import GP-PRO/PBIII project files without conversion. This migration barrier has sustained demand for GP2300 replacement units and spare panels in the aftermarket.

Sourcing Hard-to-Find & Obsolete GP2300 Parts

The GP2300 series has been discontinued by Pro-face. OEM replacement units are no longer available through standard distribution channels. DriveKNMS maintains a dedicated inventory of GP2300 series panels, including GP2301-TC41-24V, GP2300-TC41-24V, GP2400-TC41-24V, and associated communication modules. Stock is sourced from decommissioned plant equipment, verified against original Pro-face specifications, and held in climate-controlled storage to prevent LCD degradation and PCB oxidation.

For facilities requiring long-term maintenance support beyond OEM availability, DriveKNMS provides: (1) direct replacement units from verified stock; (2) backlight replacement service for units with failed CCFL backlights; (3) battery replacement for units with SRAM data retention issues; (4) cross-reference to compatible GP3000 series replacements where project migration is feasible. Lead times for GP2301-TC41-24V units are typically 3–10 business days from confirmed order.

Quality Control for the GP2300 Range

Each GP2300 series unit processed by DriveKNMS undergoes a structured inspection and functional test protocol. Power-on verification confirms 24 VDC input regulation within ±10% tolerance. Display test sequences check for dead pixels, backlight uniformity, and touch digitizer calibration across the full active area. Serial communication ports (RS-232C, RS-422) are tested using loopback and protocol handshake verification against a reference PLC. Internal SRAM battery voltage is measured; units below 2.8 V receive battery replacement prior to shipment. Firmware version is recorded and documented with each unit. Units exhibiting display delamination, cracked touch glass, or PCB corrosion are quarantined and not offered for resale.
