Signal Types
Signal Types identified by letters A, B, C, D, E, F, G and I in
Table 3-7 are defined below.
Input Circuit Conventions
Inputs may be configured to be active high or active low.
An active high input has a pull-down resistor inside the controller, and must be connected to
Vs to turn the input ON, i.e. make the input active. Alternatively, the input may be turned on
by connecting it to an external +5V or +24V supply.
An active low input has a pull-up resistor to Vs inside the controller, and must be connected
to 0V to make the input active.
