IS200BICRH1A

About the IS200BICRH1A

The IS200BICRH1A functions within the Mark VI system as a bridge interface board. This board is used in Innovation Series Medium Voltage/GP Type H drives and provides an interface between the bridge and the drive control. The IS200BICRH1A has:

• eight digital optically isolated inputs and outputs 
• three analog feedback inputs
  • one at 0-10V
  • two at 0-20 mA
• a backplane connector marked P1 used for:
  • fault string control
  • isolated I/O control
  • bridge control
• a backplane connector marked P2 used for:
  • control board interfacing
  • logic power supply connections
• two total fault string inputs
  • one utilized for the interlock contacts' panel series string
  • the other applied for the interlock contacts' system string
• eight relay outputs (solid state)
  • route to the CTBC terminal board through a CABP board
  • each of theseis indicated by a yellow LED
  • each is optically isolated from the control 

Unique IS200BICRH1A Terminal Connections

The IS200BICRH1A has two terminal boards mounted in the front faceplate. These are marked TB1 and TB2. The board has two backplane connectors, eighteen LEDs, two fuses, and eight user TP test points. The board has more test points, they are not relevant to the end user. All test points for the end-user are accessible via an opening in the board’s front faceplate. This IS200BICRH1A product also has a crucial General Electric-intended application in the processes of both MA and MB contactor control, as once again delegated in the above-included instructional manual materials. With this in mind, this IS200BICRH1A product has a series of closely-defined voltage ratings for these contactors as follows:

• For the MA Form C Contactor:  6 A at 125 V ac, .6 A at 110 V dc, and 2 A at 30 V dc voltage
• For the MB Form A Contactor: 6 A at 125 V ac, .6 A at 110 V dc, and 2 A at 30 V dc voltage as well
