Figure 5. Location and use of voltage control jumpers on a typical I/O adapter module input board
4. Once the I/O adapter module has been selected, check the settings of the voltage control
jumpers located on the I/O adapter module input board(s). All eight versions of the I/O
module input boards shown in Figure 5 are identical, with the exception of the placement of
the two voltage control jumpers J4 and J5. Note the location of these jumpers in Figure 5.
For 48V operation both jumpers must be in the 48V position. For 125V
operation both jumpers must be in the 125V position. The 250V modules
should have both jumpers in the 125V position. See Table 2.
