Key Technical Specifications

This GE IS200TRTDH1C IS200TRTDH1CCC board operates from a 24V DC power supply. It terminates 16 RTD input channels for turbine control systems. The unit measures 22 cm in length, 17 cm in width, and 4.5 cm in height. Its total weight reaches 0.7 kg without any packaging materials.

The GE IS200TRTDH1C IS200TRTDH1CCC includes 16 RTD conditioning circuits with excitation. Additionally, it features one 50-pin ribbon connector for host interface. A single 6-pin terminal block connects the DC power input. The board contains 16 RTD conditioners, 1 FPGA, 8 voltage regulators, 24 resistors, and 18 capacitors.

GE IS200TRTDH1C IS200TRTDH1CCC stores energy using one electrolytic capacitor. This capacitor provides 100 µF at 35V rating for input filtering. Consequently, the board maintains stable readings during 20 millisecond power fluctuations. Therefore, temperature measurements remain accurate in noisy industrial environments.

Design and Integration

Both the GE IS200TRTDH1C and IS200TRTDH1CCC versions share identical RTD conditioning circuitry. These boards use four-layer PCB construction with guarded analog traces for noise rejection. Consequently, the GE IS200TRTDH1C IS200TRTDH1CCC operates reliably from -10°C to +55°C ambient temperature.

For installation, you need M3 screws for the four mounting holes. The board draws 150 mA typical current from the 24V DC supply. Each RTD input supports 2-wire or 3-wire sensor connections. We recommend using shielded twisted-pair cables for all RTD field connections.

Practical Application

This RTD input termination board connects PT100 temperature sensors to a turbine control system. It monitors bearing, winding, and exhaust gas temperatures continuously. The GE IS200TRTDH1C IS200TRTDH1CCC then routes conditioned signals to the host controller. Therefore, it serves as a temperature interface for GE turbine control panels.
