IS220PRTDH1A is a Resistance Temperature Device Input Module manufactured and designed by General Electric as part of the Mark VIe Series used in distributed control systems. An RTD input terminal board and one or more I/O Ethernet networks are connected electrically by the Resistance Temperature Device (RTD) Input (PRTD) pack. An acquisition board dedicated to the thermocouple input function is included in the pack, along with a processor board that is shared by all Mark VIe distributed I/O packs. Up to eight RTD inputs can be supported by the I/O pack, while the TRTD terminal boards can support up to sixteen RTD inputs. A DC-37 pin connector that links directly to the terminal board connector for the pack, as well as a three-pin power input, are used for input. There are two RJ45 Ethernet connectors for the output. Indicator LEDs are used to display visual diagnostics.

The RTD input terminal boards TRTDH1D, H2D, and SRTD board are all compatible with PRTDH1A, but the DIN-rail mounted DRTD board is not. The compatibility information is provided in the table below.
The TRD input circuit is galvanically isolated by the PRTD. This necessitates modifications to the TRTDH1D and TRTDH2D boards' terminal board transient protection. The board's H1D version offers filtering that is compatible with the PRTD standard scan rate. When the rapid scan rate of PRTD is chosen, the H2D version of the terminal board offers less filtering to enable proper performance. Although there won't be any physical harm, if PRTD is mounted on an earlier version of the TRTD board, an incompatibility will be detected.
The I/O pack or module function-specific acquisition board is connected to the processor board. The soft-start circuit ramps up the voltage available on the processor board when input power is applied. The processor reset is turned off and the local power supply is turned on in order. After finishing self-test routines, the processor loads application code from flash memory that is particular to the I/O pack or module type. To verify that the application code, acquisition board, and terminal board are correctly matched, the application code reads the board ID information. When there is a good match, the processor makes an effort to start Ethernet connections by asking for a network address.
The dynamic host configuration protocol (DHCP), which is the industry standard, and the terminal board's unique identifier are both used in the address request. Following Ethernet startup, the CPU runs the application, programs the on-board logic, and permits the acquisition board to start working.
The whole circuitry required to enable the I/O pack to function from one or two Ethernet inputs is contained in the processor application code. Both network pathways are constantly active when two Ethernet inputs are used. The I/O pack or module operation will not be hampered by a failure of either network, and the functioning network connection will reveal the failure. Compared to a traditional hot-backup system, where the second port is only used when the primary port fails to function, this configuration is more fault tolerant. The processor's Ethernet ports automatically negotiate between half-duplex and full-duplex operation at speeds between 10 MB/s and 100 MB/s.
The processor board is common to all Mark VIe Ethernet I/O packs or modules. It contains the following:
