Electrical Connections
All analog devices connected to the ASI
must be referenced to the ground (GND)
connection; some examples are shown
below.
l
All auxiliary analog input ground
connections are internally connected
together.
l
All auxiliary analog output ground
connections are internally connected
together.
l
Analog devices with both ground and
common outputs can share these out-
puts with their power supply ground.
l
LI-7550 analog inputs are electrically
isolated from the LI-7550 power
input.
l
LI-7550 analog outputs are elec-
trically isolated from the LI-7550
power input and isolated from the
analog inputs.
Connecting Sensors to the ASI
There are gland plugs on the ASI top cover, through which the sensor wires pass,
after which they are connected to the appropriate screw terminals. Follow these
steps to attach sensors or power to the ASI:
