Product Description
The IS200DTCIH1ABB board is described as a Simplex DIN-Rail Mounted Contact Input Terminal Board. It was designed by General Electric and is one of the many models used in the Mark VI Turbine Control systems. One of the features of this model is that it will connect to a VCRC processor board for assistance with the twenty-four contact inputs. The connection will be made through a 37-pin cable. This model is considered the smaller and more compact version of the TBCI model. When using the VCRC models, two can be connected to maximize the inputs and make up a total of forty-eight contact inputs. Please note that another board can be used with the IS200DTCIH1ABB model, which is a VTCC model, but it is highly recommended that the VCRC be used with this DTCI model instead.
The IS200DTCIH1ABB model is also considered a discrete Input/Output model. It is considered a box-type model and has several defining characteristics that make the model unique. The characteristics of the model are as follows:
- 2.5 mA/point
- Three 10 mA/point inputs
- 18-32 VDC
- Optical Isolation
- 1 ms SOE
These characteristics and how they operate with a VCRC card can be found in the GER-4193A Speedtronic Mark VI Turbine Control System Instruction Guide.
As previously mentioned the IS200DTCIH1ABB model is virtually the same as the Mark VI TBCI model but is just more compact and will perform the same on-board signal conditioning functions, except for the fact that it is scaled for operation at 24 VDC. For more information refer to the GEH-6421C Speedtronic Mark VI Volume II Instruction Guide.
