conventional circuit diagrams are connected up using input contacts and relay
coils.
Pico GFX-70 circuit diagram:
First specify which input and output terminals you wish to use in your circuit.
The signal states on the input terminals are detected in the circuit diagram with
the input contacts I, R* or RN. The outputs are switched in the circuit diagram
with the output relays Q, S or SN.
