Power supply wiring
The ground (GND) and “SUP –“
terminals are connected
internally to the ground terminal.
Connect the screw terminal on
the end plate to ground for surge
protection.
Expanson I/O power and RS-485 serial connection
An on-board RS-485
terminating resistor provides
line attenuation for long runs.
Place terminating resisters
at each end of the RS-485
cable.
Confi guration switches
Use the DIP switches in the
side access panel to select
analog input voltage and
current, external boot, and
default configuration settings.
