Product Description
The IS200TRLYH1BDC model is part of the Mark VI series but can be used with the Mark VIe or Mark VIeS series. This board is described by General Electric as a Relay Output with Coil Sensing Termination Board. The IS200TRLYH1BDC model can be used in Simplex and Triple Modular Redundant (TMR) applications. It should be noted that this model can work with an I/O pack depending on the pack used, different amounts are required based on the system the model is used in; for example, when used in TMR systems, there are three I/O packs per network connector on each.
The IS200TRLYH1BDC printed circuit board is a rectangular board with several different electronic components. The far left of the IS200TRLYH1BDC is occupied by two (2) large black terminal blocks. These terminal blocks contain a series of cube-shaped components known as terminals. An additional terminal block, which is smaller than the others, is positioned at the top of the IS200TRLYH1BDC. The terminals blocks are labeled TB1, TB2, and TB3. Many solid black components have been grouped along the center of the IS200TRLYH1BDC. Sitting on either side of these black components is a row of transistors. These transistors alternate with circular red metal oxide varistors. Twelve of these MOVs may be found on the IS200TRLYH1BDC. A potentiometer, also known as a variable resistor, is situated at the bottom of the IS200TRLYH1BDC and is solid white. Four mid-sized connector ports have been placed vertically along the right edge of the IS200TRLYH1BDC. Positioned throughout the IS200TRLYH1BDC is a collection of small components like capacitors, diodes, and resistors.
