About the IS230TNCIH4C

The IS230TNCIH4C board is marketed by General Electric as a printed circuit board. This circuit board can be mounted in either a thirteen or twenty-one VME slot-type rack. It will typically be used with a control module when used in a simplex architecture type system but if the chosen architecture is triple redundant it will be used with an IONet, main processor card, and the control module. 

There are two main communication types that the TNCI model can be used with, these are the Unit Data Highway, which is an Ethernet-based LAN type of communication, and an IONet communication. Please note that the UDH communication driver will typically be associated with the main processor card located within the Mark VI System. 

While the IS230TNCIH4C board is made up of over a dozen capacitors, resistors, and even more small components, the main visual components of this model are the two terminal blocks, three sub-D pin connectors, two female plug-type connectors, and the metal oxide varistors for which there are twenty-five. The two terminal blocks are labeled TB1 and TB2 and are located near the bottom edge of the board, the metal oxide varistors are located just above the two terminal blocks. The three sub-D pin connectors, which are located near the top edge of the board, are each made up of thirty-seven pins. 

As mentioned above the IS230TNCIH4C model will be used with a control module but in some circumstances, it is required that a backup protection module also be used.
