3-3.1.3 Digital Outputs
Each of the Genesis II Direct Digital Controller’s twelve digital output channels (Terminals 42–65)
consists of a single-pole, double-throw (SPDT) relay. The two terminals assigned to each channel
represent the associated relay’s Normally Open (NO) and Common (COM) contacts.
Digital output relay contacts are rated at 24VAC, 2A. Good practice is to use pilot relays for the actual
switching functions, particularly when it applies to inductive loads such as coils, solenoids and
motors. This protects the relays of the Digital Output channel and has the advantage of allowing the
pilot relays to be installed adjacent to the controlling switch-gear.
Refer to Table 3-4 for Digital Output terminal number assignments.
