5.6 DISCRETE INPUT MODULES (DI0-17)
The Discrete Input Modules (DI0-17) generate logic levels based on the applied voltages or contact condition on the associated termi-
nals. Inputs DI2-17 are active only when the appropriate hardware options are installed. The 18 Discrete Input Modules are provided in
Table 5-6. Each one can be configured separately (total combined DIs and DOs for controller cannot exceed 18).
