Product Description:

  • General Electric’s IS220PRTDH1A Resistance Temperature Device Input Module is part of the Mark VIe Series, which is utilized in distributed control systems.
  • The Resistance Temperature Device (RTD) Input (PRTD) pack electrically connects an RTD input terminal board and one or more I/O Ethernet networks.
  • The pack includes an acquisition board devoted to the thermocouple input function, as well as a processor board shared by all Mark VIe distributed I/O packs. The I/O pack can handle up to eight RTD inputs, whilst the TRTD terminal boards can support up to sixteen RTD inputs.
  • For input, a DC-37 pin connection that connects directly to the pack’s terminal board connector, as well as a three-pin power input, are employed.
  • The output has two RJ45 Ethernet connections. Visual diagnostics are displayed via indicator LEDs.
  • The PRTD galvanically isolates the TRD input circuit. This needs changes to the terminal board transient protection on the TRTDH1D and TRTDH2D boards.
  • The H1D version of the board includes filtering that is compatible with the PRTD standard scan rate. When the PRTD’s quick scan rate is selected, the H2D version of the terminal board provides less filtering to ensure optimal performance.
  • Although there would be no physical harm, an incompatibility will be discovered if the PRTD is mounted on an earlier version of the TRTD board.
  • The processor board is linked to the I/O pack or module function-specific acquisition board. When input power is connected, the soft-start circuit increases the voltage available on the processor board.
  • In sequence, the processor reset is turned off and the local power supply is switched on. Following completion of self-test procedures, the processor loads application code from flash memory specific to the I/O pack or module type.
  • The application code examines the board ID information to ensure that the application code, acquisition board, and terminal board are all appropriately matched.
  • When there is a good match, the CPU attempts to initiate Ethernet connections by requesting a network address.
  • In the address request, the industry standard dynamic host configuration protocol (DHCP) and the terminal board’s unique identity are both employed.
  • Following Ethernet startup, the CPU runs the application, codes the on-board logic, and powers on the acquisition board. The processor application code contains all of the hardware necessary to enable the I/O pack to work from one or two Ethernet inputs.
  • When two Ethernet inputs are utilized, both network paths are always active. A failure of either network will not impede the operation of the I/O pack or module, and the working network connection will expose the problem.
  • This arrangement is more fault tolerant than a standard hot-backup system, in which the second port is only used when the primary port ceases to work.
  • The Ethernet ports on the CPU automatically switch between half-duplex and full-duplex operation at rates ranging from 10 MB/s to 100 MB/s.
