Functional Description

IS200PHRAH1A is an HART-enabled analog I/O module developed by General Electric. It is a part of GE Mark VIe system. The PHRA (Processor and Acquisition Board) serves as an electrical interface between Ethernet-based I/O networks and an analog input/output terminal board. Integrated into the Mark VIe distributed I/O system, this device is designed to handle the precise data acquisition and communication needs for analog input and output functions. It combines both processor and acquisition capabilities, providing a seamless connection between field devices and control systems. This pack is composed of A processor board, which is common across all Mark VIe™ distributed I/O packs. An acquisition board, specifically tailored to support the analog input functions.

Analog Input/Output Capabilities

• First 8 Inputs: These can be configured either as ±5V voltage inputs or 4-20 mA current loop inputs. This versatility allows the PHRA to accommodate different types of field devices depending on the application requirements.
• Last 2 Inputs: These inputs can be configured as either ±1 mA or 4-20 mA current loop inputs, offering additional flexibility for specialized applications that require low-level current input measurements.
• Current Loop Inputs: The load termination resistors necessary for current loop inputs are located directly on the terminal board. The PHRA senses the voltage across these resistors, enabling accurate measurements of current.
• Additionally, the PHRA is capable of supporting two 4-20 mA current loop outputs, which are commonly used in process control and industrial automation systems for controlling devices like actuators and valves.

HART Communication

A key feature of the PHRA is its ability to relay Highway Addressable Remote Transducer (HART®) messages between HART-enabled field devices and an Asset Management System (AMS). In 4-20 mA mode, the PHRA provides the ability to communicate with HART-enabled devices, which are widely used for field diagnostics, configuration, and monitoring purposes. This functionality allows the PHRA to act as an intermediary for transferring vital data between the control system and field devices, ensuring better asset management and operational efficiency.

Input and Output Connectivity

• Input: The PHRA connects to the Ethernet network via dual RJ45 Ethernet connectors for reliable and high-speed data communication. A 3-pin power input is used to supply the necessary power to the device.
• Output: The module provides a DC-62 pin connector, which directly connects to the corresponding terminal board connector, ensuring proper integration with the control system.

Diagnostic and Communication Features

• Visual Diagnostics: The PHRA module includes indicator LEDs that provide real-time feedback on the status of the module, helping users quickly identify any operational issues.
• Serial Communication: Local diagnostic serial communication is supported through an infrared port, which allows for further troubleshooting and detailed system analysis without the need to directly connect via wired interfaces.

Installation

• Mount the Terminal Board: Securely install the desired terminal board in the appropriate location.
• Connect the PHRA I/O Pack: Plug the PHRA I/O pack directly into the terminal board connector.
• Secure the Pack: Use the threaded studs adjacent to the Ethernet ports to mechanically secure the pack. These studs fit into a mounting bracket specific to the terminal board type. Adjust the bracket location to ensure that no right-angle force is applied to the DC-62 pin connector between the pack and the terminal board. This adjustment only needs to be made once during the product’s lifetime.
• Connect Ethernet Cables: Plug in one or two Ethernet cables, depending on your system configuration. The pack will function through either Ethernet port. If dual connections are used, it's recommended to connect ENET1 to the network associated with the R controller.
• Apply Power: Power the pack by connecting the power cable to the connector on the side of the pack. There’s no need to disconnect power from the cable during this step, as the I/O pack has built-in soft-start functionality to manage current inrush during power application.
• Configure the I/O Pack: Complete the necessary configuration for the I/O pack based on your system's requirements.
