Signal Name Definition
Relay output contacts:
Relay N C (N = 0 to 7) Relay output common contact; this contact is always
used with relay output connections.
Relay N NC Relay output normally connected contact; this contact is connected
to the Out N C contact when power is off or when a 0 is written to the
relay’s control bit in the relay control register, and it is disconnected
when power is on and a 1 is written to the relay’s control bit.
Relay N NO Relay output normally open contact; this contact is disconnected
when power is off or when a 0 is written to the relay’s control bit in
the relay control register, and it is connected to the Out N C contact
when power is on and a 1 is written to the relay’s control bit.
Optoisolated input contacts:
Opto N + (N = 0 to 3) Optoisolated input contact, high side
Opto N - Optoisolated input contact, low side; opto inputs are polarized
