AXIS Q7406 - Unit connectors
Pin assignments for the I/O Connector of the AXIS Q7900 Rack
The following connection diagram gives an example of how to connect an auxiliary device to the AXIS Q7406.
Pin Function Description
1 Channel 1, Configurable I/O 1 Digital input - Connect to GND to activate, or
leave floating (or unconnected) to deactivate.
Digital output - Uses an open-drain NFET tran-
sistor with the source connected to GND. If used
with an external relay, a diode must be con-
nected in parallel with the load, for protection
against voltage transients.
Min input = - 40V DC
Max input = + 40V DC
Max load = 100mA
Max voltage = + 40V DC
