The IS220PRTDH1A is a General Electric resistance temperature device input module. The module is part of the GE Mark VIe Speedtronic system, one of the last Speedtronic systems available. The Speedtronic family was created by General Electric in the 1960s to manage industrial gas and steam turbines, including popular versions such as the Mark I, Mark II, Mark IV and Mark VI.

The IS220PRTDH1A is an I/O package designed to work with the terminal board. When used with specific terminal boards such as IS200TRTDH2D, IS200SRTDH1A or IS200SRTDH2A, it is approved for use in hazardous locations. The machine has its own power supply.

Only simple resistance devices like RTDS should be connected to the RTD input on the IS220PRTDH1A. The cables used for these connections shall have appropriate insulation as specified in the local electrical code.

The front panel of the IS220PRTDH1A includes LED indicators for two Ethernet ports on the I/O unit, as well as power and ATTN LED indicators. Ports are located on the side of the device.
Before adding any kind of packaging material, the unit weighs about 4.40 pounds. The dimensions are 34 x 18 x 10 cm. The device is CE marked and UL certified.
