GE IS220PRTDH1B Resistance Temperature Device Input Pack

GE IS220PRTDH1B Resistance Temperature Device Input Pack  

The IS220PRTDH1B Resistance Temperature Device Input pack (PRTD) provides the electrical interface between one or two I/O Ethernet networks and a RTD input terminal board. The PRTD contains a processor board common to the distributed I/O packs and an acquisition board specific to the RTD input function. The PRTD I/O pack is capable of handling up to eight RTD inputs. Two PRTD packs may be plugged into a single TRTD board to handle 16 simplex inputs.

Input to the I/O 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 RJ-45 Ethernet connectors. Visual diagnostics are provided through indicator LEDs.

Compatibility

The PRTD I/O pack includes one of the following compatible BPPx processor boards:

• The PRTDH1A contain a BPPB processor board.

• The PRTDH1B contains a functionally compatible BPPC that is supported in the ControlST* software suite V04.06 and later.

The PRTD pack is compatible with the RTD input terminal boards TRTDH1D, TRTDH2D, and SRTD. Simplex redundancy is only supported.

The PRTD input board accepts eight three-wire RTD inputs from the RTD terminal board.

The pack supplies a 10 mA dc multiplexed (not continuous) excitation current to each RTD, which can be grounded or ungrounded. The eight RTDs can be located up to 300 meters (984 feet) from the distributed I/O cabinet with a maximum two-way cable resistance of 15 Ω.

The A/D converter in the pack samples each signal and the excitation current four times per second for normal mode scanning, and 25 times per second for fast mode scanning, using a time sample interval related to the power system frequency. Linearization for the selection of RTD types is performed in software by the processor. RTD open and short circuits are detected by out of range values. An RTD, which is determined to be out of hardware limits, is removed from the scanned inputs to prevent adverse effects on other input channels. Repaired channels are reinstated automatically in 20 seconds, or can be manually reinstated.
