GE DS200TCEAG1BNE | TCEA OVERSPEED PROTECTION BOARD

Description

PRODUCT OVERVIEW

GE DS200TCEAG1BNE belongs to GE DS200 series rack safety protection circuit boards, abbreviated as TCEA board, which is the independent hardware overspeed protection card of GE Speedtronic Mark V gas & steam turbine control system, independent of the main control logic to realize hard-loop overspeed trip protection for turbine rotating machinery.The board adopts a dedicated safety microprocessor + multi-group PROM solidified safety logic program, receiving pulse signals from three redundant magnetic pickup speed sensors on the turbine shaft. It monitors the actual speed value in real time, judges the overspeed state according to two-stage fixed protection thresholds, and outputs hard dry contact trip signals to drive the emergency shut-off valve and safety interlock loop once the threshold is exceeded, with a response speed less than 100ms to avoid turbine flying accidents.

Equipped with multiple external signal connectors (J1~J5) respectively for speed signal input, working power supply, trip contact output, 4-20mA status analog output and backplane bus communication; onboard hardware jumpers can match different types of speed sensors, and the whole PCB is coated with industrial three-proof conformal coating. Built-in signal surge suppression, overvoltage and overcurrent protection circuits, standard rack plug-in installation mode, matched with the TCPS power supply board for power supply. Widely used in thermal power steam/gas turbine units, petrochemical large turbine compressor equipment safety system maintenance and spare parts replacement work.

FAQ

1. What core safety functional positioning does GE DS200TCEAG1BNE undertake in the Mark V turbine distributed control system?DS200TCEAG1BNE is an independent hard-loop overspeed protection board separated from the main control logic. It collects multi-redundant shaft speed signals independently, executes safety judgment logic through dedicated safety chips, and outputs hard contact shutdown signals to realize the last safety defense line against turbine overspeed runaway faults.
2. What redundant design is adopted for the speed acquisition input of DS200TCEAG1BNE? What sensor signal types are supported?The board is designed with 3 mutually redundant speed sampling channels, compatible with two mainstream pulse output signals of field magnetic pickups: 120VAC alternating pulse and 24VDC direct pulse, and realizes signal voting judgment to improve the safety of measurement data.
3. What two-level overspeed protection threshold values are preset for DS200TCEAG1BNE? What is the index of protection action response speed?The primary alarm threshold is 110% of the turbine rated speed, and the secondary forced shutdown trip threshold is 115% of the rated speed; the hardware response time from detecting the overspeed state to the contact action is guaranteed to be less than 100ms.
4. What two forms of output signals are provided by DS200TCEAG1BNE for external system connection?One is 2 groups of passive dry contacts with 250VAC/5A load capacity, which are used for hard wiring of safety interlock and emergency shutdown loops; the other is standard 4~20mA analog current signal, which feeds back real-time speed operating parameters to the upper monitoring platform.
5. How to realize the adaptive matching between DS200TCEAG1BNE and different types of on-site speed sensors?Four groups of configurable hardware jumpers are reserved on the PCB surface. Maintenance engineers can switch the internal signal receiving mode of the board through jumper combination arrangement without rewriting the system firmware program to match different pickup signals.
6. What anti-interference and environmental adaptation reinforcement measures are configured on the hardware circuit of DS200TCEAG1BNE?Each signal input channel is equipped with surge absorption and voltage limiting protection devices; the whole PCB is coated with industrial three-proof coating, which can resist moisture, dust and corrosive gas erosion, adapting to the long-term uninterrupted working environment of power plant central control rooms.
7. Will the pre-owned DS200TCEAG1BNE circuit boards you supply pass standardized full safety performance inspection before leaving the warehouse?All second-hand circuit boards will complete long-term power-on aging test, multi-point overspeed threshold simulation trigger test and dry contact action durability test before delivery to ensure that the safety protection function is effective and reliable after being put into the formal turbine safety control loop.
8. What is the actual shipment lead time for spot stock DS200TCEAG1BNE finished products?Spot inventory is stored in our domestic warehouse, and formal shipment procedures will be fully completed within 3 working days after we receive and complete the verification of your official payment voucher.
