Core Functions

1. Local Operator HMI Visualization & Keypad Input Processing This integrated operator‑interface board integrates 32 status LED indicators and twenty‑one 4‑character 16‑segment alphanumeric display modules, plus keypad‑scan circuit for local panel push‑buttonsMoore Auto…. It receives turbine real‑time process data, fault codes, alarm events and set‑point values from Mark‑V main controller, and drives on‑board LED and digit‑displays for on‑site operator reading. Meanwhile, it scans keypad key‑press signals and transmits operator‑input commands back to system processor for local parameter modification, mode switching and fault‑acknowledge operations.
2. Backplane High‑speed Data Communication with Main Controller Equipped with 40‑pin rear system connector, it exchanges bidirectional data with Mark‑V rack core processor boards via internal backplane bus. Downlink: receive turbine operating parameters, alarm logs and system status; Uplink: send operator keyboard input commands to control CPU for execution. On‑board EPROM chips store dedicated KLDC firmware for display‑driving and key‑scan logic.More products: www.plcva.com

1. On‑board Hardware Configuration & Diagnostic Indication Single configurable hardware jumper on PCB supports function‑mode adjustment for different turbine application setups. Built‑in hardware self‑test circuit monitors board power supply, display‑driver chip and communication‑link health. LED status lamps show board running state and communication‑failure alarms for quick field troubleshooting. Conformal‑coated PCB provides humidity‑resistant and anti‑corrosion performance for power‑plant cabinet environment.
2. Local Control‑panel Standalone Man‑machine Interaction Realizes local cabinet‑door operator‑panel functions without external HMI workstation. Operators can view turbine speed, temperature, pressure, vibration, load value, trip‑alarm information directly on‑site, acknowledge alarms, modify local set‑points and view historical fault event records. It supports basic turbine commissioning and maintenance operations at cabinet side.

Applications & Purposes

DS215KLDCG1AZZ03A / DS200KLDCG1AAA is legacy dedicated local operator‑interface PCB for GE Speedtronic Mark‑V gas‑turbine & steam‑turbine control system. It cannot run independently and must cooperate with complete Mark‑V rack hardware and firmware.

Typical Application Industries ‑ Thermal power plants: combined‑cycle gas‑turbine & steam‑turbine generator units ‑ Petrochemical & refinery: turbine‑driven large‑compressor sets ‑ Oil‑gas industry on‑site power‑generation equipment ‑ Heavy‑industry plant turbine‑control system lifecycle‑extension maintenance projects

GE DS215KLDCG1AZZ03A / DS200KLDCG1AAA Display Board PCB

Main Purposes

1. Serve as local cabinet‑door human‑machine interface for Mark‑V turbine control system, display real‑time turbine process parameters, trip‑fault codes and alarm events for field operators.
2. Process keypad input signals, realize local on‑site operation: alarm acknowledge, parameter checking, set‑point adjustment during turbine commissioning and maintenance.
3. Complete bidirectional data exchange between local operator panel and Mark‑V main control processor, act as physical signal bridge for local man‑machine interaction.
4. Provide visual hardware‑fault indication for operator‑panel communication and board‑self‑diagnosis, convenient for on‑site maintenance staff troubleshooting.
5. Used as OEM spare‑part replacement: DS215KLDCG1AZZ03A is full‑functional ready‑to‑use spare unit; DS200KLDCG1AAA is bare‑PCB hardware for refurbishment and firmware re‑programming, restoring local‑operator‑panel function after original‑board failure.
