GENERAL ELECTRIC IS220PRTDH1A Resistance Temperature Device

The IS220PRTDH1A is a Resistance Temperature Device Input Module from General Electric. This module is part of GE’s Mark VIe Speedtronic system, which was one of the final Speedtronic systems available. The Speedtronic line was created by GE in the 1960s for the management of industrial gas and steam turbines and included popular versions like the Mark I, Mark II, Mark IV, and Mark VI. This  IS220PRTDH1A device's Mark VI Turbine Control System Series instructional manual materials may be rather difficult to source online, given the fact that General Electric has been removing many Mark Series instructional documents in the wake of their initial manufacturing release. This  IS220PRTDH1A device is actually not the originally-produced device of its specific Mark VI Series functionality, as that would have to be considered the IS220PRTDH1 parent Resistance Temperature Input Module notable not utilizing this  IS220PRTDH1A product's A-rated primary functional product revision.

The  IS220PRTDH1A is an I/O pack designed to work in conjunction with a terminal board. It is approved for use within hazardous locations when used with specific terminal boards like the IS200TRTDH2D, IS200SRTDH1A, or the  IS220PRTDH1A. This unit has its own power supply. Only resistive simple apparatus like RTDs should be connected to RTD inputs on the  IS220PRTDH1A .Cabling used for these connections should have suitable insulation as specified in local electrical codes.
