ds200tcqeg2a

DS200TCQEG2A is an LM 6000 IO Processor Board developed by GE under the Mark V series. The R1 core houses the LM 6000 IO Processor Board (TCQE), which scales and conditions extra analog I/O signals. These signals include magnetic pick up, TTL pulse rate inputs, LM vibration inputs, proximitor vibration inputs, proximitor position inputs, 420 mA outputs, RTD inputs, and 420 mA outputs. The STCA board receives data from the TCQE board via the 3PL connector. All LM applications use this board.

• The board scales and conditions Analog I/O Signals. It is located in the core. This board is used for all LM applications.
• It is populated with eight jumpers and four 34-pin connectors. This board also has one Programmable Logic Device and multiple EPROM modules.
• The JQQ connectors reads the LM vibration inputs, proximeter vibration inputs, and pulse rate speed sensor inputs.The component plays an important role in communicating data to the STCA board.
• Always adhere to the manufacturer's installation guidelines while installing or replacing the board. Since the DS200 series is obsolete,we suggest you have a shelf stock of minimum 2 cards of every panel.

LVDT/LVDR Circuit

TCQE LVDT/LVDR Circuit sLinear Variable Differential Transformers (LVDT) or Linear Variable Differential Reactors (LVDR) are used to detect position. The JLL connection is used to read the position signals from the TBQE terminal board. For usage by the Control Sequence Program, these location signals have been scaled and conditioned (CSP). The TCQE also performs diagnostics on these signals. Through the TCQC board, the excitation signals are written to the QTBA terminal board. The LVDT/Rís are commonly used for regulating servo valve outputs; although these are not associated with the TCQA/TCQC servo systems.

DS200TCQEG2A Proximitor Vibration Inputs

The JQQ connector is used to read the proximitor vibration inputs from the TBQE terminal board. The I/O configuration constants obtained from the operator interface are used to scale, condition, and process the signals. The results are written to the STCA board through the 3PL connector.

DS200TCQEG2A RTD Circuit

The circuitry that feeds excitation to the RTDs from the TBQE terminal board is housed on the TCQE board. When the temperature varies, the resistance changes, causing the voltage on the RTD to change. A constant current is fed through the RTD. The voltage signal is measured, scaled, and adjusted by the TCQE board.
