FUNCTIONAL DESCRIPTION:

IS200TPYRH1A is a Pyrometer Input Terminal Board manufactured and designed by General Electric as part of the Mark VI Series used in GE Speedtronic Control Systems. The Pyrometer Input (TPYR) terminal board is wired to two pyrometers and two Keyphasor Proximitor probes for shaft reference. The resulting 10 voltage signals are cabled to the VPYR board, which samples them at up to 200,000 samples per second. Three DC-37 connectors on TPYR connect to three VPYRs. Connections can be simple on a single connector (JR1), or TMR using all three connectors. In TMR applications, the input signals are fanned to the three connectors for the R, S, and T controls. In the Mark* VI system, TPYR works with the VPYR I/O board and supports simplex and TMR applications. With TMR systems, TPYR connects to three VPYR boards with three cables.

INSTALLATION:

Connect the wires for the two optical pyrometer inputs directly to the first terminal block. Connect the wires for the two Keyphasor probes directly to the second terminal block. Each block is held down with two screws and has 24 terminals accepting up to #12 AWG wires. A shield termination strip attached to the chassis ground is located immediately to the left of each terminal block. 28 V DC power for the sensors comes in from the R, S, and T VPYR through the JR1, JS1, and JT1 connectors.

OPERATION:

Two infrared pyrometers dynamically measure the temperature profile of the rotating turbine blades. Each pyrometer is powered by a +24 V dc and a –24 V dc source, diode selected on TPYR from voltages supplied by the three VPYRs. Four 4-20 mA signals are returned from each pyrometer, representing the following blade measurements:

• Average temperature
• Maximum peak temperature
• Average peak temperature
• Fast dynamic profile, with 30 kHz bandpass, providing the full signature.

Each 4-20 mA input generates a voltage across a resistor. The signal is sent to VPYR where it is multiplexed and converted. VPYR can be configured for different numbers of turbine buckets, with up to 30 temperature samples per bucket.

FREQUENTLY ASKED QUESTIONS:

What is a pyrometer input terminal board?

This would be an interface board used to connect a pyrometer sensor to a data acquisition system or a control system. It provides terminals or connectors for wiring connections.

How do I wire a pyrometer to the input terminal board?

Typically, the pyrometer would have wires for power, ground, and signal output. These wires would be connected to corresponding terminals on the input terminal board using appropriate wiring techniques.

What type of connectors does the input terminal board support?

This would depend on the specific model of the terminal board. Common connector types might include screw terminals, spring terminals, or specialized connectors compatible with the pyrometer and the system it's being integrated with.
