FUNCTIONAL DESCRIPTION:

IS220PHRAH1B, REV D is an HART Enabled Analog I/O Module manufactured and designed by General Electric as part of the Mark VIe Series used in GE Distributed Turbine Control Systems. The Highway Addressable Remote Transducer (HART) Enabled Analog I/O pack (PHRA) provides the electrical interface between one or two I/O Ethernet networks and an analog input/output terminal board. The PHRA contains a BPPX processor board common to the distributed I/O packs and an acquisition board specific to the analog input function.

The I/O pack is capable of handling up to 10 analog inputs, the first eight of which can be configured as �5 V inputs, or 4-20 mA current loop inputs. The last two inputs can be configured as +1 mA or 4-20 mA current inputs. The load termination resistors for current loop inputs are located on the terminal board, and voltage is sensed across these resistors by the PHRA. The PHRA also includes support for two 4-20 mA current loop outputs. In addition, in 4-20 mA mode, the PHRA can relay HART messages between HART-enabled field devices and an Asset Management System (AMS). These HART-enabled field devices can be connected through any of the inputs or outputs. Input to the I/O pack is through dual RJ-45 Ethernet connectors and a 3-pin power input. Output is through a DC-62 pin connector that connects directly with the associated terminal board connector. Visual diagnostics are provided through indicator LEDs.

INSTALLATION:

• Securely mount the desired terminal board.
• Directly plug one PHRA I/O pack into the terminal board connector.
• Mechanically secure the I/O pack using the threaded studs adjacent to the Ethernet ports. The studs slide into a mounting bracket specific to the terminal board type. The bracket location should be adjusted such that there is no right-angle force applied to the DC-62 pin connector between the I/O pack and the terminal board. The adjustment should only be required once in the service life of the product.
• Plug in one or two Ethernet cables, depending on the system configuration. The pack will operate over either port. If dual connections are used, the standard practice is to connect ENETI to the network associated with the R controller.
• Apply power to the pack by plugging in the connector on the side of the pack. It is not necessary to remove power from the cable before plugging it in because the I/O pack has inherent soft-start capability that controls current inrush on power application.

ANALOG INPUT HARDWARE:

The PHRA accepts input voltage signals from the terminal board for all 10 input channels. The analog input section consists of an analog multiplexer block, several gain and scaling selections, and a 16-bit analog-to-digital converter (DAC). The inputs can be individually configured as �5 V scale signals, depending on the input configuration. The terminal board provides a 250 burden resistor when configured for current inputs, yielding a 5 V signal at 20 mA. These analog input signals are first passed through a second-order, passive, low-pass filter network with poles at 12.5 Hz and 48.3 Hz. Voltage signal feedback from the analog output circuits and calibration voltages are also sensed by the PHRA analog input section.

FREQUENTLY ASKED QUESTIONS:

What is the GE IS220PHRAH1B, REV D?

The IS220PHRAH1B, REV D is an I/O pack used in the Mark VIe system to interface with analog field devices that utilize the HART protocol. It supports 10 inputs and 2 outputs.

Does this pack support 2-wire and 4-wire transmitters?

Yes, when used with the appropriate terminal board, the PHRA pack can interface with both loop-powered (2-wire) and externally powered (4-wire) analog transmitters.

How does HART communication benefit turbine operation?

HART allows the system to monitor device health and internal diagnostics in real-time. For example, a valve positioner can report its actual travel or air pressure through the digital HART layer while the analog signal controls its position, reducing the need for manual field inspections.
