GE IS200TRTDH1D RTD Input Terminal Board

GE IS200TRTDH1D RTD Input Terminal Board

Functional Description

The IS200TRTDH1D RTD Input (TRTD) terminal board accepts 16, three-wire RTD inputs when the I/O packs

are placed on both J-ports.These inputs are wired to two barrier type terminal blocks. The inputs have noise

suppression circuitry to protect against surge and high frequency noise. TRTD communicates with the PRTDs,

which convert the inputs to digital temperature values and transfer them to the Mark VIe controller.

Compatibility

In the Mark VIe control system, TRTDH1D and TRTDH2D work with the PRTD I/O pack and support simplex

applications only. Two PRTD I/O packs plug into the TRTD for a total of 16 inputs.

The PRTD provides galvanic isolation of the RTD input circuit. This requires changes in the terminal board

transient protection, provided on the TRTDH1D and TRTDH2D boards. The TRTDH1D terminal board

provides filtering compatible with the standard scan rate of PRTD. The TRTDH2D version of the terminal

board provides less filtering to allow proper performance when the fast scan rate of PRTD is selected. TRTD

board versions previous to TRTDH#D are not supported by the PRTD, although no physical damage will

occur.
