IS200TRLYS1B - TERMINATION BD., RELAY

IS200TRLYS1B is a relay termination board developed by GE, which is a type of printed circuit board under the Mark VI series. It was developed as a huge rectangular circuit board having a miscellany of electronic components.

• It consists of two vertically oriented terminal blocks, each of which has a succession of metal and silver blocks. The terminals, which are all labeled with white numbers ranging from one to twenty-four, sit in the center of a long row of relays or contactors.
• Transparent acrylic covers the square-shaped relays on this board. A transistor is also included on this board, and each transistor is paired with a circular red MOV (metal oxide varistor). Three white jumpers are seen, along with a bevy of small integrated circuits arranged in lines.
• Integrated circuits are compact devices with a self-contained network of very small components. Always follow the manufacturer's installation instructions when installing or replacing the board.
