More Information

Overview Manuals Core Integration Position & Temp Speed Protection Current Range

Features:

  • Links the LM terminal hardware to the R1-core analog processing chain.
  • Supports selectable milliamp outputs alongside multiple turbine-sensor inputs.
  • Applies channel definitions downloaded through the Mark V operator interface.
DS200TCQEG2A is powered from TCPS through 2PL and communicates with STCA and TCQA over the shared 3PL data bus.

The board accommodates both resistive temperature channels and dynamic feedback such as vibration, shaft speed and position.

A correct installation therefore depends on matching connector destinations, jumper-selected output ranges and the saved I/O constants.

The General Electric DS200TCQEG2A Mark V LM I/O Processor Board may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

R1 Board Connections

  • Operating Power: 2PL distributes board power from the TCPS supply.
  • Analog Bus: 3PL joins TCQE with STCA and TCQA inside R1.
  • Field Termination: JLL and JQQ link the processor to TBQE.
  • Speed Source: JJQ brings shaft-speed channels from PTBA.

Conditioned Feedback Paths

  • LVDT/LVDR: Position feedback enters through JLL and is scaled for the control sequence.
  • RTD Excitation: TCQE supplies steady current to the connected temperature elements.
  • Signal Conversion: Resistance variation is measured as a voltage change on the board.
  • Engine Use: Configured channels can represent LP and HP compressor inlet temperatures.

Pulse and Relay Functions

  • LP Pickup: JQJ receives magnetic-pickup signals used for low-pressure shaft speed.
  • TTL Channels: Two TTL pulse-rate inputs are available through JLL.
  • Shear Logic: Pulse feedback contributes to load-coupling and LP-shaft shear protection.
  • Relay Command: JO routes the resulting control commands toward the TCRA relay board.

Analog Output Selection

  • Two Outputs: The board drives a pair of current loops through JLL.
  • Enable Jumpers: JP4 and JP6 configure the individual output circuits.
  • Scale Jumpers: JP5 and JP7 distinguish the 20 mA and 200 mA maximum ranges.
  • Diagnostics: Output-circuit checks are performed on TCQE before the field connection.
Description
Operating as the TCQE function, General Electric DS200TCQEG2A scales supplementary analog I/O for SPEEDTRONIC Mark V LM6000 control. Its assigned position is location three in the R1 core, where the board receives operating power from TCPS through 2PL.

The position and temperature side of General Electric DS200TCQEG2A uses JLL to read LVDT/LVDR and RTD signals from TBQE. The same connector provides the return path for two current outputs, keeping measurement inputs and commanded analog outputs within the LM termination arrangement.

Dynamic channels reach General Electric DS200TCQEG2A through different interfaces: JQQ carries LM and proximity-vibration inputs plus pulse-rate sensors, while JJQ reads high- and low-pressure shaft-speed feedback from PTBA. JO separately writes load-coupling and LP-shaft shear relay commands toward TCRA.

Before General Electric DS200TCQEG2A can interpret these channels, the I/O Configuration Editor must contain the correct RTD type, pulse-rate, proximity, vibration, accelerometer and position constants. Current-output jumpers establish the physical range independently of those software definitions.

Technical notes
DS200TCQEG2A is a Mark V LM TCQE processor board with 2PL power, 3PL data transfer and TBQE/PTBA sensor interfaces.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
What should be verified if DS200TCQEG2A powers up but its sensor values remain invalid?
For DS200TCQEG2A, compare the JLL/JQQ cable destinations with the programmed channel types and confirm that 3PL communication reaches STCA.
How is RTD feedback handled by General Electric DS200TCQEG2A?
A steady excitation current is supplied by General Electric DS200TCQEG2A, which measures the resulting voltage change and scales the value for the I/O engine.
Why must the current-output jumpers and software settings agree on DS200TCQEG2A?
DS200TCQEG2A uses hardware to select the physical maximum current, while software defines how the channel is used; mismatched settings produce an incorrect loop range.
Which DS200TCQEG2A connector is relevant to load-coupling shear protection?
Pulse information reaches DS200TCQEG2A through the speed-input paths, and JO carries the related relay-control command toward TCRA.
Can General Electric DS200TCQEG2A process proximity probes and accelerometers identically?
No. General Electric DS200TCQEG2A requires the I/O constants to identify the connected vibration or accelerometer channel correctly.
Where does DS200TCQEG2A obtain its operating supply inside R1?
DS200TCQEG2A receives power from the TCPS board over the 2PL connector rather than from the TBQE field terminals.
