ADLINK PCI-7260 - Manual (Page 27)

Register Format 17
3.2 Relay Output Control Register
There are 8 non-latching relays on each PCI-7260 board. Each
non-latching relay is controlled by each bit of the control register.
The setting “1” means the non-latching relay is in RESET condi-
tion. Under the RESET condition, the normal open(NO) signal line
is ‘open’ from the common(COM) line and the normal close(NC)
signal line is connected with the common line. The setting “0”
means the normal open signal line is now closed, while the NC
signal is open.
For more information about the non-latching relay and software
function library, please refer to sections 4.1 and 5.3, respectively.
