Functional Description

IS220PRTDH1BC is an RTD Input Board developed by GE. It is a part of the Mark VIe control system. This RTD input module serves as the interface between RTD sensor terminal boards and the Mark VIe I/O Ethernet networks, enabling accurate temperature monitoring across various industrial applications. It is part of the distributed I/O architecture of the Mark VIe system, ensuring flexibility, scalability, and ease of integration.

Features

• Dual Ethernet Compatibility: The I/O pack supports connection with one or two I/O Ethernet networks, enhancing redundancy and communication reliability.
• Modular Construction: The pack consists of a general-purpose processor board, which is shared across all Mark VIe distributed I/O packs. It also contains an RTD-specific acquisition board, which manages the unique requirements of RTD signal conditioning and data acquisition.
• RTD Input Capacity: The standard configuration allows the pack to support up to eight RTD inputs. When paired with TRTD terminal boards, the capacity extends to 16 RTD inputs, providing increased channel density for applications demanding extensive temperature sensing.
• High Accuracy and Reliability: Designed to interface with 3-wire RTD sensors, which help minimize errors caused by lead wire resistance. Ensures precise temperature measurements vital for maintaining process control in power plants, refineries, and other industrial environments.

Installation Procedure

Step 1: Mount the Terminal Board

Securely install the appropriate RTD terminal board in its designated location within the control cabinet or I/O panel. Ensure it is properly aligned and fastened to prevent movement or vibration.

Step 2: Attach the RTD Input Packs

Plug one or two input packs directly into the connectors on the terminal board:

• Single pack configuration supports up to 8 RTD channels.
• Dual pack configuration supports up to 16 RTD channels when using a TRTD terminal board.
• Ensure firm and proper insertion into the DC-37 pin connector for a solid electrical connection.

Step 3: Mechanically Secure the Packs

Use the threaded inserts located next to the Ethernet ports on the PRTD pack to secure it mechanically:

• Attach a mounting bracket suitable for your terminal board type.
• Carefully align the bracket to avoid placing any right-angle force on the DC-37 connector.
• The alignment process is a one-time adjustment, ensuring long-term mechanical integrity and preventing connector stress.

Step 4: Connect Ethernet Cables

Connect one or two Ethernet cables to the PRTD pack, depending on your system's redundancy and network design:

• For simplex operation, connect a single Ethernet cable to ENET1.
• For redundant network operation, connect both ENET1 and ENET2.
• As a standard configuration, connect ENET1 to the network associated with the R controller to maintain proper control system hierarchy.

Step 5: Apply Power

Connect the power supply cable to the side connector on the PRTD pack:

• There is no need to de-energize the cable before connection.
• The I/O pack features an inbuilt soft-start capability that limits inrush current during power-up, protecting both the module and the power source.

Step 6: Configure the I/O Pack

Once installed and powered, proceed with configuring the I/O pack:

• Use the GE ToolboxST or ControlST software to assign RTD channels, perform calibration, and apply system-specific settings.
• Confirm correct communication with the Mark VIe controller.
• Perform diagnostic checks to ensure successful integration.

Frequently Asked Questions

What is IS220PRTDH1BC?
It is an RTD Input Board designed and manufactured by GE.

How many RTD inputs can the Board handle?
The pack can handle up to 8 RTD inputs on its own. When used with TRTD terminal boards, it can manage up to 16 RTD inputs.

Does the pack support redundancy?
Yes, the Board supports dual Ethernet network connections for redundant communication. This ensures continuous operation even if one network path fails.

What types of RTDs are supported?
The I/O pack is designed to work with 3-wire RTD sensors, which help reduce measurement errors due to lead wire resistance.

Is it necessary to power down the system before connecting the power cable?
No. The pack includes a soft-start feature that controls inrush current when power is applied, so it is safe to connect the power cable without shutting down the system.
