POWER
The Digital Gateway operates at 24 vac. Power is
applied through terminals 1, 2 and 3. Terminal 1 is 24
vac high side, terminal 2 is 24 vac low side and
terminal 3 is ground. (Figure 17.)
OUTPUTS
The 3 triac outputs of the Digital Gateway share a
common power source which is terminal 4. Terminal 4
is internally connected to the 24 vac power source.
Terminal 5 is the open output, supplying power to the
open contactor. Terminal 6 is the close output, supply-
ing power to the close contactor. Terminal 7 is the
Program 1 output. It can be used to power a relay
which can be used for a variety of things. (See
OPTIONAL PROGRAMS on page 13.)
An RC network and MOV are connected across each
output for noise suppression. An external MOV is
recommended across any contactor coil or solenoid
coil. The maximum rating for each output is 1-amp
inductive continuous. (See Figure 17.)
