FUNCTIONAL DESCRIPTION:

IS220PRTDH1BF is a Resistance Temperature Device Input Pack manufactured and designed by General Electric as part of the Mark VIe Series used in GE Distributed Control Systems. The Resistance Temperature Device (RTD) Input (PRTD) pack provides the electrical interface between one or two I/O Ethernet networks and an RTD input terminal board. The pack contains a processor board common to all Mark VIe distributed I/O packs and an acquisition board specific to the thermocouple input function. The I/O pack is capable of handling up to eight RTD inputs and can handle 16 RTD inputs on the TRTD terminal boards. Input to the pack is through a DC-37 pin connector that connects directly with the associated terminal board connector, and a three-pin power input. Output is through dual RJ45 Ethernet connectors. Visual diagnostics are provided through indicator LEDs.

COMPATIBILITY:

PRTDH1A is compatible with the RTD input terminal boards TRTDH1D, H2D, and the SRTD board, but not the DIN-rail mounted DRTD board. The following table gives details of the compatibility. Control mode refers to the number of I/O packs used in a signal path:

• Simplex uses one I/O pack with one or two network connections.
• Dual uses two I/O packs with one or two network connections.
• TMR uses three I/O packs with one network connection on each pack.

The PRTD provides galvanic isolation of the TRD input circuit. This requires changes in the terminal board transient protection, provided on the TRTDH1D and TRTDH2D boards. The H1D version of the board provides filtering compatible with the standard scan rate of PRTD. The H2D version of the terminal board provides less filtering to allow proper performance when the fast scan rate of PRTD is selected. If PRTD is mounted on an earlier revision of the TRTD board, an incompatibility will be reported, although no physical damage will occur.

INSTALLATION:

• Securely mount the desired terminal board.
• Directly plug one or two PRTD (for simplex control of eight or 16 RTDs) into the terminal board connectors.
• Mechanically secure the packs using the threaded inserts adjacent to the Ethernet ports. The inserts connect with 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-37 pin connector between the pack and the terminal board. The adjustment should only be required once in the life of the product.
• Plug in one or two cables (depending on system configuration) to negotiate proper operation over either port. If dual connections are used the standard practice is to hook ENET1 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 the inherent soft-start capability that controls the current inrush on the power application.
• Use the ToolboxST application to configure the I/O pack as necessary.

FREQUENTLY ASKED QUESTIONS:

How does an RTD sensor work?

RTD sensors work on the principle that the electrical resistance of certain metals increases predictably with temperature. Typically, platinum is used as the sensing element in industrial RTDs due to its stable and linear resistance-temperature relationship.

What are the advantages of using RTD sensors?

RTD sensors offer several advantages, including high accuracy, stability, and repeatability over a wide temperature range. They also have excellent long-term stability and are less prone to drift compared to thermocouples.
