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
