19DV IOB COMPONENTS AND WIRING
The components listed in Tables 2-5 are available at the user's
terminal block on the IOB. Some are available only if the unit
is operating in Remote mode. Table 6 lists SIOB inputs and out-
puts. Figures 2-4 show IOB wiring diagrams and Fig. 5 is the
legend. Figures 6-9 show additional control wiring.
