3: INSTALLATION AND WIRING
3-6 OPENNET CONTROLLER USER’S MANUAL
Output Wiring
Relay Output Transistor Sink Output
Caution
• Terminal name “NC” means “No Connection.” Do not connect output or any other wiring to NC terminals.
• If relays or transistors in the OpenNet Controller output modules should fail, outputs may remain on or off. For
output signals which may cause heavy accidents, provide a monitor circuit outside the OpenNet Controller.
• Connect a fuse to the output module, selecting a fuse appropriate for the load.
• Use UL1015AWG22 or UL1007AWG18 wires
for output wiring.
• When driving loads which generate noise, such
as electromagnetic contactors and solenoid
valves, use a surge absorber for AC power or a
diode for DC power.
