NOTE: Binary Output (BO1—BO3) terminals
are relays and are used with SC
terminals instead of GND terminals.
NOTE: Universal (analog) inputs (AIx/INx) and
outputs (AOx/OUTx) are used with GND
terminals. They can be configured to
emulate binary (on/off or voltage/no-
voltage) objects.
NOTE: Universal Input (INx) terminal = Analog
Input (AIx) object or Binary Input (BIx).
Universal Output (OUTx) terminal =
Analog Output (AOx) object. Relay
output (RLYx) = Binary Output (BOx)
object.
NOTE: Unused inputs and outputs are
available for use with custom
configuration and programming in
KMC software.
