IS200TBCIH21CD Contact input terminal board

The surface of the IS200TBCIH21CD contains many electronic components. The most striking of these components are two large black terminal boards, each containing 24 terminals. Each terminal is marked with a white number 1 to 48. To the right of these two (2) terminal boards is a long string of solid red mov or metal oxide rheostat. Metal oxide rheostat is circular. Two (2) solid white connectors can be found in the middle of the top of the IS200TBCIH21CD. Along the right edge of the IS200TBCIH1C are three (3) black and silver jack connector ports that are aligned vertically. The center of the IS200TBCIH21CD is filled with countless small pieces made of silver metal that look like very small rectangles. These components are called diodes. The diodes are arranged in parallel rows of four (4) diodes. On the left side of these diodes, a small vertical resistance line is aligned between the white connector and the black and silver connector ports. The resistors are divided into blue, black and white colors. Two more (2) vertical rows can be found below this top row.
