Emerson 406A124H17 WDPF Infrared Touch Console
Product Overview
Emerson 406A124H17 is an industrial‑grade infrared (IR) touch console, originally designed by Westinghouse for the WDPF (Westinghouse Distributed Processing Family) DCS platform. Also known as model E20FEC‑WE3, it serves as a dedicated operator HMI (Human‑Machine Interface) integrating an IR touchscreen, display controller, and communication interface for WDPF control rooms. Built to withstand harsh industrial environments with high dust, vibration, and EMI/RFI interference, it enables reliable, intuitive process monitoring and control. Factory‑tested and certified by Emerson, the 406A124H17 is a direct drop‑in replacement for legacy WDPF touch consoles, ensuring full backward compatibility and minimal downtime for system maintenance or upgrades.

Core Functions
The 406A124H17 functions as the primary interactive HMI for WDPF DCS operator workstations, combining high‑contrast CRT display with durable infrared touch input. Its core role is to render real‑time process graphics, alarm panels, trend data, and system diagnostics from WDPF controllers, while allowing operators to execute commands, adjust setpoints, and navigate screens via the IR touch interface. The infrared touch technology is highly resistant to dust, moisture, and surface contaminants—ideal for industrial control rooms—supporting accurate, drift‑free touch operation without physical contact wear. The integrated display controller optimizes video output for industrial viewing conditions, ensuring stable brightness and contrast over extended operation. With built‑in EMI shielding and surge protection, it maintains signal integrity in high‑interference environments, preventing display distortion or touch input errors. It connects directly to WDPF LocalBus and MMI ports, enabling seamless data exchange with no additional adapters required.

Compatibility
Emerson 406A124H17 is fully compatible with all Westinghouse WDPF DCS HMI components, including WEStation operator consoles, WDPF MMI workstations, and LocalBus power modules (e.g., 406A124H15). It connects directly to WDPF controller video outputs and LocalBus communication ports, supporting plug‑and‑play integration without hardware or software modifications. The unit maintains backward compatibility with all legacy WDPF system revisions, replacing older touch console models (e.g., 406A124H07) seamlessly. It also integrates with WDPF alarm and event logging systems, ensuring consistent display and interaction for critical process data across the control room.
Industrial Applications
This IR touch console is deployed exclusively in WDPF‑controlled industrial facilities where reliable, interactive HMI is critical:
Power Generation: Thermal power plants, combined‑cycle facilities, and nuclear power stations
Petrochemical Industry: Oil refineries, natural gas processing plants, and chemical manufacturing complexes
Heavy Manufacturing: Pulp and paper mills, mining operations, cement plants, and metallurgical facilities
Process Industries: Any WDPF‑based industrial plant requiring durable, dust‑resistant touchscreen operation
Installation Guidelines
Prior to installation, verify compatibility with the WDPF system revision and workstation configuration. Place the console on a flat, stable surface in the control room, ensuring 150 mm of clearance around ventilation slots for cooling. Connect the WDPF video cable from the controller to the console’s video input port, ensuring a secure fit. Attach the LocalBus communication cable to the rear panel port, aligning pins correctly. Connect the 110 VAC power cord to a grounded industrial outlet, avoiding shared circuits with high‑power equipment. Power on the unit and confirm the CRT illuminates with the WDPF boot screen; verify touch functionality by tapping the screen to navigate menus. Adjust brightness/contrast via front‑panel controls for optimal viewing. Route cables away from high‑EMI sources (motors, transformers) to prevent interference.
Maintenance and Troubleshooting
Perform monthly visual inspections to check for enclosure damage, loose cables, or abnormal CRT flickering. Clean the CRT screen and IR touch frame quarterly with a soft, dry cloth to remove dust buildup—avoid harsh chemicals that may damage the IR sensors. Conduct annual electrical safety checks, verifying grounding integrity and insulation resistance. Common issues include unresponsive touch input, often caused by dust on the IR frame; clean the frame and restart the unit. Flickering display typically stems from EMI interference or a failing CRT; re‑route cables or replace the CRT module. No video output may result from a faulty power supply or loose video cable; check connections and power input. Replace the unit if irreparable CRT or touch controller faults occur to maintain control room reliability.
