Working Principle: The IS215WEPAH2B receives raw analog signals from field devices via terminal boards connected to I/O cores R1, R2, and R3. The board’s internal circuitry scales and conditions these signals to appropriate voltage or current levels. For example, 4-20 mA signals are converted and routed via the JB connector to the TBQC terminal board. Conditioned signals are then multiplexed and transmitted over the 3PL data bus to the core processor (STCA board). Simultaneously, it routes generator and line signals via the JE connector to the TCQC board for system-wide synchronization and control.
Installation Requirements:
- Slot Placement: Install the board in the designated TCQA slot within the Mark V I/O core rack.
- Connector Mating: Ensure all connectors (2PL, 3PL, JA, JB, JD, JE, JF, JG) are properly aligned and fully seated before securing the board.
- Jumper Configuration: Set hardware jumpers J1, J2, J5, J6, J7, and J8 according to the system design specifications before applying power.
- Terminal Board Wiring: Connect the appropriate terminal boards (TBQA, TBQB, TBQC) to the corresponding connectors on the IS215WEPAH2B.
