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.

Hardware Tips and Specifications

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 IS200SRTDH2A. 

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.

The front panel of the IS220PRTDH1A includes LED indicators for the I/O unit’s two ethernet ports, 

as well as a Power and an ATTN LED indicator.Ports are located on the side of the unit.

This unit weighs approximately 4.40 pounds before the addition of any sort of packing materials. Dimensions are 34 x 18 x 10 cm.

The IS220PTCCH1A is a thermocouple input manufactured by General Electric for use within the Mark VI/Mark VIe systems. 

These systems were some of the later Speedtronic controls system technology systems developed and

released by General Electric for the management and control of gas, hydro and steam industrial turbine systems. 

The Mark VIe Series that this IS220PTCCH1A Thermocouple Input Module belongs to must be considered a decently-strong step up 

from the Mark V Turbine Control System Series even, given the fact that the Mark V Series has a more-restricted set of specific 

applications in steam and gas turbine automated drive assembly settings alone. 

While this is true, this IS220PTCCH1A device's greater Mark V Turbine Control System Series is still definable as 

one of the lastly-developed GE Mark product series to make use of the patented Speedtronic control system technology as mentioned above, 

while increases its overall market desirability by itself.
