Solid State Relays (Triacs)
There are 7 separate solid state relays (small triacs) on the C5000 terminal board. The output
terminals for these triacs are T1 to T7. See below for information about the use of these
outputs.
Auxilliary Output for Fill active and Beacon lights
In Single Hose CNG Dispensers, the 230V low current output T7 is turned ON for the duration
of the fill.
This can be used to switch a contactor or relay to operate an external light to indicate a fill is
in progress (example a Beacon Light)
GPIO wiring for remote push to start
In this application the start signal will wire to IN1 terminal on the J1 connector. The signal
from the PLC should be at least a 0.5 second 3 to 24 volt DC pulse.
The end of fill indicator is wired to the OUT terminal on the J2 connector. This is an open
collector output. Depending on the PLC you might have to install pullup resistors on the input
to the PLC.
The Output pulse signal is to be wired to the OUT terminal on the J2 connector. Like the end
of fill indicator, the output is and open collector.
