2.3.6 VOLTAGE CONNECTIONS
Note: Up to four Input Boards may be present; stacked 4 high. Input Board 1 is the bottom board. Two
versions of Input Board s may be found, see Figure 2-9 and Figure 2-9A.
Input Board 1 is used for Input 1 and, if equipped, Input 2. Input Board 2 is used for Input 3 and Input 4, if
equipped. Input Board 3 is for Input 5 and Input 6. Input Board 4 is for Input 7 and Input 8.
Connect positive (+) leg to terminal 1 and negative (-) leg to terminal 2 on the Input Board(s) to be volt input.
Terminal block 1 (TB1) is Input 1, 3,5 and 7 and terminal block 2 (TB2) is Input 2, 4, 6, and 8.
NOTE: INPUT CONDITIONING JUMPERS MUST BE POSITIONED AS SHOWN FOR VOLT INPUT IN EITHER
FIGURE 2-8 OR 2-8A DEPENDING ON WHICH CIRCUIT BOARD IS FITTED. ALSO NOTE: THERE IS NO
SENSOR BREAK DETECTION FOR ZERO BASED VOLT INPUTS. EXAMPLE: 0-5V.
